-I am an Associate Professor of [Data Science](https://datascience.virginia.edu/){:target="\_blank"}
-and [Computer Science](https://engineering.virginia.edu/departments/computer-science){:target="\_blank"} at
-the [University of Virginia](https://www.virginia.edu/){:target="\_blank"}.
-My research covers a range of topics including distributed systems,
-serverless and cloud computing, storage systems, operating systems,
-and high-performance computing.
-My current research focuses on designing scalable, high-performance, and
-easy-to-use computer **systems** that manage and process huge volume of
-**data**.
-
-Currently I am working on:
-(1) **Serverless and FaaS:** improving serverless computing using a
-end-to-end approach that cuts across the entire software-hardware
-stack: *(stateful) applications, middleware, platforms, and
-lower-level OS/HW*;
-(2) **Sys4ML:** building better (computing and storage) systems for
-(distributed) ML applications;
-and (3) **ML4Sys:** improving systems software and infrastructure
-management by using learned or data-driven approaches.
-
-I am the recipient of an
-[NSF CAREER Award](https://www.nsf.gov/awardsearch/showAward?AWD_ID=2045680&HistoricalAwards=false){:target="\_blank"} (2021),
-an Amazon Research Award (2021),

-and a [Samsung GRO 2023 Award](https://www.sait.samsung.co.kr/saithome/about/collabo_recipients.do){:target="\_blank"} (2023).
-Prior to joining UVA, I was an Assistant Professor of
-[Computer Science](https://cs.gmu.edu/){:target="\_blank"} at
-[George Mason University](https://www.gmu.edu/){:target="\_blank"}, from 2017 to 2022.
-I received my Ph.D. degree in [Computer Science](https://cs.vt.edu/){:target="\_blank"} from
-[Virginia Tech](https://vt.edu/){:target="\_blank"}, working with Dr.
-[Ali R. Butt](https://people.cs.vt.edu/butta/){:target="\_blank"}.
-During my Ph.D. I spent two summers at IBM Research Almaden in 2013
-and 2014, and six months at Dell EMC Princeton Office in 2015.
-
-
-## selected projects
-
-Most of my projects are open-source and available on our group's [GitHub page](https://github.com/ds2-lab){:target="\_blank"}.
-
-
-* **InfiniStore:** Storing large and small objects on a dynamic fleet of serverless functions with only 3% of ElastiCache's cost but without sacrificing performance and availability.
- [[ASPLOS'23](https://tddg.github.io/assets/pdf/asplos23-lambdafs-ae.pdf){:target="\_blank"}]: [[GitHub](https://github.com/ds2-lab/LambdaFS){:target="\_blank"}] --

- [[FAST'20](https://www.usenix.org/conference/fast20/presentation/wang-ao){:target="\_blank"}]: [[GitHub](https://github.com/ds2-lab/infinicache){:target="\_blank"}]
-
-* **Wukong:** Scaling out Python parallel programs (e.g., Dask applications) on FaaS without worrying about tedious cluster management. Wukong uses a new decentralized scheduling technique, which decentralizes resource orchestration to each individual serverless function, thereby enabling high elasticity and high scalability.
- [[SoCC'20](https://tddg.github.io/assets/pdf/socc20-wukong.pdf){:target="\_blank"}]
- [[PDSW'19](https://arxiv.org/abs/1910.05896){:target="\_blank"}]: [[GitHub](https://github.com/ds2-lab/Wukong){:target="\_blank"}]
-
-* **FaaSNet:** A highly scalable container provisioning framework that can provision thousands of 10+GB serverless function containers with just a few seconds. FaaSNet is currently deployed at [Alibaba Function Compute](https://www.alibabacloud.com/product/function-compute){:target="\_blank"}.
- [[ATC'21](https://www.usenix.org/conference/atc21/presentation/wang-ao){:target="\_blank"}]: [[GitHub](https://github.com/ds2-lab/FaaSNet){:target="\_target"}] [[Alibaba Cloud Blog](https://www.alibabacloud.com/blog/597937){:target="\_blank"}]
-
-* **SFS:** Linux CFS is not ideal for short-lived serverless function workloads. SFS instead optimizes the turnaround time for transient function jobs.
- [[SC'22](https://arxiv.org/abs/2209.01709){:target="\_blank"}]: [[GitHub](https://github.com/ds2-lab/SFS){:target="\_blank"}]
-
-* **SHADE:** A common practice in deep learning training is to randomly shuffle all training samples epoch by epoch. With SHADE, you can cache the most important training samples without losing training quality.
- [[FAST'23](https://www.usenix.org/conference/fast23/presentation/khan)]: [[GitHub](https://github.com/R-I-S-Khan/SHADE){:target="\_blank"}]
-
-* **DIGEST:** Scaling GNN training using a disaggregated storage.

- /**
- * This file contains the parser used to parse out a TeX expression from the
- * input. Since TeX isn't context-free, standard parsers don't work particularly
- * well.
- *
- * The strategy of this parser is as such:
- *
- * The main functions (the `.parse...` ones) take a position in the current
- * parse string to parse tokens from. The lexer (found in Lexer.js, stored at
- * this.lexer) also supports pulling out tokens at arbitrary places. When
- * individual tokens are needed at a position, the lexer is called to pull out a
- * token, which is then used.
- *
- * The parser has a property called "mode" indicating the mode that
- * the parser is currently in. Currently it has to be one of "math" or
- * "text", which denotes whether the current environment is a math-y
- * one or a text-y one (e.g. inside \text). Currently, this serves to
- * limit the functions which can be used in text mode.
- *
- * The main functions then return an object which contains the useful data that
- * was parsed at its given point, and a new position at the end of the parsed
- * data. The main functions can call each other and continue the parsing by
- * using the returned position as a new starting point.
- *
- * There are also extra `.handle...` functions, which pull out some reused
- * functionality into self-contained functions.
- *
- * The earlier functions return ParseNodes.
- * The later functions (which are called deeper in the parse) sometimes return
- * ParseFuncOrArgument, which contain a ParseNode as well as some data about
- * whether the parsed object is a function which is missing some arguments, or a
- * standalone object which can be used as an argument to another function.

- /* This file contains a list of functions that we parse, identified by
- * the calls to defineFunction.
- *
- * The first argument to defineFunction is a single name or a list of names.
- * All functions named in such a list will share a single implementation.
- *
- * Each declared function can have associated properties, which
- * include the following:
- *
- * - numArgs: The number of arguments the function takes.
- * If this is the only property, it can be passed as a number
- * instead of an element of a properties object.
- * - argTypes: (optional) An array corresponding to each argument of the
- * function, giving the type of argument that should be parsed. Its
- * length should be equal to `numArgs + numOptionalArgs`. Valid
- * types:
- * - "size": A size-like thing, such as "1em" or "5ex"
- * - "color": An html color, like "#abc" or "blue"
- * - "original": The same type as the environment that the
- * function being parsed is in (e.g. used for the
- * bodies of functions like \textcolor where the
- * first argument is special and the second
- * argument is parsed normally)
- * Other possible types (probably shouldn't be used)
- * - "text": Text-like (e.g. \text)
- * - "math": Normal math
- * If undefined, this will be treated as an appropriate length
- * array of "original" strings
- * - greediness: (optional) The greediness of the function to use ungrouped
- * arguments.
- *
- * E.g. if you have an expression
- * \sqrt \frac 1 2
- * since \frac has greediness=2 vs \sqrt's greediness=1, \frac
- * will use the two arguments '1' and '2' as its two arguments,
- * then that whole function will be used as the argument to
- * \sqrt. On the other hand, the expressions
- * \frac \frac 1 2 3
- * and
- * \frac \sqrt 1 2
- * will fail because \frac and \frac have equal greediness
- * and \sqrt has a lower greediness than \frac respectively. To
- * make these parse, we would have to change them to:
- * \frac {\frac 1 2} 3
- * and
- * \frac {\sqrt 1} 2
- *
- * The default value is `1`
- * - allowedInText: (optional) Whether or not the function is allowed inside
- * text mode (default false)
- * - numOptionalArgs: (optional) The number of optional arguments the function
- * should parse. If the optional arguments aren't found,
- * `null` will be passed to the handler in their place.
- * (default 0)
- * - infix: (optional) Must be true if the function is an infix operator.
- *
- * The last argument is that implementation, the handler for the function(s).
- * It is called to handle these functions and their arguments.
- * It receives two arguments:
- * - context contains information and references provided by the parser
- * - args is an array of arguments obtained from TeX input
- * The context contains the following properties:
- * - funcName: the text (i.e. name) of the function, including \
- * - parser: the parser object
- * - lexer: the lexer object
- * - positions: the positions in the overall string of the function
- * and the arguments.
- * The latter three should only be used to produce error messages.
- *
- * The function should return an object with the following keys:
- * - type: The type of element that this is. This is then used in
- * buildHTML/buildMathML to determine which function
- * should be called to build this node into a DOM node
- * Any other data can be added to the object, which will be passed
- * in to the function in buildHTML/buildMathML as `group.value`.

- // Nested SVGs
- // Many of the KaTeX SVG images contain a nested SVG. This is done to
- // achieve a stretchy image while avoiding distortion of arrowheads or
- // brace corners.
-
- // The inner SVG typically contains a very long (400 em) arrow.
-
- // The outer SVG acts like a window that exposes only part of the inner SVG.
- // The outer SVG will grow or shrink to match the dimensions set by CSS.
-
- // The inner SVG always has a longer, thinner aspect ratio than the outer
- // SVG. After the inner SVG fills 100% of the height of the outer SVG,
- // there is a long arrow shaft left over. That left-over shaft is not shown.
- // Instead, it is sliced off because the inner SVG is set to
- // "preserveAspectRatio='... slice'".
-
- // Thus, the reader sees an arrow that matches the subject matter width
- // without distortion.
-
- // Some functions, such as \cancel, need to vary their aspect ratio. These
- // functions do not get the nested SVG treatment.
-
- // Second Brush Stroke
- // Low resolution monitors struggle to display images in fine detail.
- // So browsers apply anti-aliasing. A long straight arrow shaft therefore
- // will sometimes appear as if it has a blurred edge.
-
- // To mitigate this, these SVG files contain a second "brush-stroke" on the
- // arrow shafts. That is, a second long thin rectangular SVG path has been
- // written directly on top of each arrow shaft. This reinforcement causes
- // some of the screen pixels to display as black instead of the anti-aliased
- // gray pixel that a single path would generate. So we get arrow shafts
- // whose edges appear to be sharper.

Wukong: A Scalable and Locality-Enhanced Framework for Serverless Parallel Computing
Benjamin Carver, Jingyuan Zhang, Ao Wang, Ali Anwar, Panruo Wu, and Yue Cheng
In Proceedings of the 11th ACM Symposium on Cloud Computing 2020
Executing complex, burst-parallel, directed acyclic graph (DAG) jobs poses a major challenge for serverless execution frameworks, which will need to rapidly scale and schedule tasks at high throughput, while minimizing data movement across tasks. We demonstrate that, for serverless parallel computations, decentralized scheduling enables scheduling to be distributed across Lambda executors that can schedule tasks in parallel, and brings multiple benefits, including enhanced data locality, reduced network I/Os, automatic resource elasticity, and improved cost effectiveness. We describe the implementation and deployment of our new serverless parallel framework, called Wukong, on AWS Lambda. We show that Wukong achieves near-ideal scalability, executes parallel computation jobs up to 68.17X faster, reduces network I/O by multiple orders of magnitude, and achieves 92.96% tenant-side cost savings compared to numpywren.
TiFL: A Tier-Based Federated Learning System

In Proceedings of the 29th International Symposium on High-Performance Parallel and Distributed Computing 2020
Federated Learning (FL) enables learning a shared model acrossmany clients without violating the privacy requirements. One of the key attributes in FL is the heterogeneity that exists in both resource and data due to the differences in computation and communication capacity, as well as the quantity and content of data among different clients. We conduct a case study to show that heterogeneity in resource and data has a significant impact on training time and model accuracy in conventional FL systems. To this end, we propose TiFL, a Tier-based Federated Learning System, which divides clients into tiers based on their training performance and selects clients from the same tier in each training round to mitigate the straggler problem caused by heterogeneity in resource anddata quantity. To further tame the heterogeneity caused by non-IID (Independent and Identical Distribution) data and resources, TiFL employs an adaptive tier selection approach to update the tiering on-the-fly based on the observed training performance and accuracy. We prototype TiFL in a FL testbed following Google’s FL architecture and evaluate it using the state-of-the-art FL benchmarks. Experimental evaluation shows that TiFL outperforms the conventional FL in various heterogeneous conditions. With the proposed adaptive tier selection policy, we demonstrate that TiFL achieves much faster training performance while achieving the same or better test accuracy across the board.

2021 Mind the Gap: Broken Promises of CPU Reservations in Containerized Multi-Tenant Clouds
Li Liu, Haoliang Wang, An Wang, Mengbai Xiao, Yue Cheng , and Songqing Chen
In Proceedings of the ACM Symposium on Cloud Computing 2021
Containerization is becoming increasingly popular, but unfortunately, containers often fail to deliver the anticipated performance with the allocated resources. In this paper, we first demonstrate the performance variance and degradation are significant (by up to 5x) in a multi-tenant environment where containers are co-located. We then investigate the root cause of such performance degradation. Contrary to the common belief that such degradation is caused by resource contention and interference, we find that there is a gap between the amount of CPU a container reserves and actually gets. The root cause lies in the design choices of today’s Linux scheduling mechanism, which we call Forced Runqueue Sharing and Phantom CPU Time. In fact, there are fundamental conflicts between the need to reserve CPU resources and Completely Fair Scheduler’s work-conserving nature, and this contradiction prevents a container from fully utilizing its requested CPU resources. As a proof-of-concept, we implement a new resource configuration mechanism atop the widely used Kubernetes and Linux to demonstrate its potential benefits and shed light on future scheduler redesign. Our proof-of-concept, compared to the existing scheduler, improves the performance of both batch and interactive containerized apps by up to 5.6x and 13.7x.
FedAT: A High-Performance and Communication-Efficient Federated Learning System with Asynchronous Tiers
Zheng Chai, Yujing Chen, Ali Anwar, Liang Zhao, Yue Cheng , and Huzefa Rangwala
In Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis 2021
Federated learning (FL) involves training a model over massive distributed devices, while keeping the training data localized and private. This form of collaborative learning exposes new tradeoffs among model convergence speed, model accuracy, balance across clients, and communication cost, with new challenges including: (1) straggler problem—where clients lag due to data or (computing and network) resource heterogeneity, and (2) communication bottleneck—where a large number of clients communicate their local updates to a central server and bottleneck the server. Many existing FL methods focus on optimizing along only one single dimension of the tradeoff space. Existing solutions use asynchronous model updating or tiering-based, synchronous mechanisms to tackle the straggler problem. However, asynchronous methods can easily create a communication bottleneck, while tiering may introduce biases that favor faster tiers with shorter response latencies.To address these issues, we present FedAT, a novel Federated learning system with Asynchronous Tiers under Non-i.i.d. training data. FedAT synergistically combines synchronous, intra-tier training and asynchronous, cross-tier training. By bridging the synchronous and asynchronous training through tiering, FedAT minimizes the straggler effect with improved convergence speed and test accuracy. FedAT uses a straggler-aware, weighted aggregation heuristic to steer and balance the training across clients for further accuracy improvement. FedAT compresses uplink and downlink communications using an efficient, polyline-encoding-based compression algorithm, which minimizes the communication cost. Results show that FedAT improves the prediction performance by up to 21.09% and reduces the communication cost by up to 8.5\texttimes, compared to state-of-the-art FL methods.

VCPU as a Container: Towards Accurate CPU Allocation for VMs
Li Liu, Haoliang Wang, An Wang, Mengbai Xiao, Yue Cheng , and Songqing Chen
In Proceedings of the 15th ACM SIGPLAN/SIGOPS International Conference on Virtual Execution Environments 2019
With our increasing reliance on cloud computing, accurate resource allocation of virtual machines (or domains) in the cloud have become more and more important. However, the current design of hypervisors (or virtual machine monitors) fails to accurately allocate resources to the domains in the virtualized environment. In this paper, we claim the root cause is that the protection scope is erroneously used as the resource scope for a domain in the current virtualization design. Such design flaw prevents the hypervisor from accurately accounting resource consumption of each domain. In this paper, using virtual CPUs as a container we propose to redefine the resource scope of a domain, so that the new resource scope is aligned with all the CPU consumption incurred by this domain. As a demonstration, we implement a novel system, called VASE (vCPU as a container), on top of the Xen hypervisor. Evaluations on our testbed have shown our proposed approach is effective in accounting system-wide CPU consumption incurred by domains, while introducing negligible overhead to the system.

MOS: Workload-Aware Elasticity for Cloud Object Stores
Ali Anwar, Yue Cheng , Aayush Gupta, and Ali R. Butt
In Proceedings of the 25th ACM International Symposium on High-Performance Parallel and Distributed Computing 2016
The use of cloud object stores has been growing rapidly in recent years as they combine key advantages such as HTTP-based RESTful APIs, high availability, elasticity with a "pay-as-you-go" pricing model that allows applications to scale as needed. The current practice is to either use a single set of configuration parameters or rely on statically configured storage policies for a cloud object store deployment, even when the store is used to support different types of applications with evolving requirements. This crucial mismatch between the different applications requirements and capabilities of the object store is problematic and should be addressed to achieve high efficiency and performance.In this paper, we propose MOS, a Micro Object Storage architecture, which supports independently configured microstores each tuned dynamically to the needs of a particular type of workload. We also design an enhancement, MOS++, that extends MOS’s capabilities through fine-grained resource management to effectively meet the tenants’ SLAs while maximizing resource efficiency. We have implemented a prototype of MOS ++ in OpenStack Swift using Docker containers. Our evaluation shows that MOS ++ can effectively support heterogeneous workloads across multiple tenants. Compared to default and statically configured object store setups, for a two-tenant setup, MOS++ improves the sustained access bandwidth by up to 79% for a large-object workload, while reducing the 95th percentile latency by up to 70.2% for a small-object workload.

2015 Taming the Cloud Object Storage with MOS
Ali Anwar, Yue Cheng , Aayush Gupta, and Ali R. Butt
In Proceedings of the 10th Parallel Data Storage Workshop 2015
Cloud object stores today are deployed using a single set of configuration parameters for all different types of applications. This homogeneous setup results in all applications experiencing the same service level (e.g., data transfer throughput, etc.). However, the vast variety of applications expose extremely different latency and throughput requirements. To this end, we propose MOS, a M icro O bject S torage architecture with independently configured microstores each tuned dynamically for a particular type of workload. We then expose these microstores to the tenant who can then choose to place their data in the appropriate microstore according the latency and throughput requirements of their workloads. Our evaluation shows that compared with default setup, MOS can improve the performance up to 200% for small objects and 28% for large objects while providing opportunity of tradeoff between two.

CAST: Tiering Storage for Data Analytics in the Cloud
Yue Cheng , M. Safdar Iqbal, Aayush Gupta, and Ali R. Butt
In Proceedings of the 24th International Symposium on High-Performance Parallel and Distributed Computing 2015
Enterprises are increasingly moving their big data analytics to the cloud with the goal of reducing costs without sacrificing application performance. Cloud service providers offer their tenants a myriad of storage options, which while flexible, makes the choice of storage deployment non trivial. Crafting deployment scenarios to leverage these choices in a cost-effective manner - under the unique pricing models and multi-tenancy dynamics of the cloud environment - presents unique challenges in designing cloud-based data analytics frameworks.In this paper, we propose CAST, a Cloud Analytics Storage Tiering solution that cloud tenants can use to reduce monetary cost and improve performance of analytics workloads. The approach takes the first step towards providing storage tiering support for data analytics in the cloud. CAST performs offline workload profiling to construct job performance prediction models on different cloud storage services, and combines these models with workload specifications and high-level tenant goals to generate a cost-effective data placement and storage provisioning plan. Furthermore, we build CAST++ to enhance CAST’s optimization model by incorporating data reuse patterns and across-jobs interdependencies common in realistic analytics workloads. Tests with production workload traces from Facebook and a 400-core Google Cloud based Hadoop cluster demonstrate that CAST++ achieves 1.21X performance and reduces deployment costs by 51.4% compared to local storage configuration.
An In-Memory Object Caching Framework with Adaptive Load Balancing
Yue Cheng , Aayush Gupta, and Ali R. Butt
In Proceedings of the Tenth European Conference on Computer Systems 2015
The extreme latency and throughput requirements of modern web applications are driving the use of distributed in-memory object caches such as Memcached. While extant caching systems scale-out seamlessly, their use in the cloud — with its unique cost and multi-tenancy dynamics — presents unique opportunities and design challenges.In this paper, we propose MBal, a high-performance in-memory object caching framework with adaptive M ultiphase load B alancing, which supports not only horizontal (scale-out) but vertical (scale-up) scalability as well. MBal is able to make efficient use of available resources in the cloud through its fine-grained, partitioned, lockless design. This design also lends itself naturally to provide adaptive load balancing both within a server and across the cache cluster through an event-driven, multi-phased load balancer. While individual load balancing approaches are being lever-aged in in-memory caches, MBal goes beyond the extant systems and offers a holistic solution wherein the load balancing model tracks hotspots and applies different strategies based on imbalance severity – key replication, server-local or cross-server coordinated data migration. Performance evaluation on an 8-core commodity server shows that compared to a state-of-the-art approach, MBal scales with number of cores and executes 2.3x and 12x more queries/second for GET and SET operations, respectively.
2013 High Performance In-Memory Caching through Flexible Fine-Grained Services
Yue Cheng , Aayush Gupta, Anna Povzner, and Ali R. Butt
In Proceedings of the 4th Annual Symposium on Cloud Computing 2013
In-memory object caches are extensively used in today’s web installations [1, 6]. Most existing systems adopt monolithic storage models and engineer optimizations on specific workload characteristics [3, 6] or operations [4, 5]. Such optimizations are insufficient as large-scale cloud workloads typically exhibit both temporal and spatial shifts - requirements vary within the same deployment over time and different parts of the same workload demonstrate different access patterns. To this end, we propose a caching tier that supports differentiated services in multiple dimensions. Since there is no best "one-size-fits-all" solution for all workload requirements, we argue that a fine-grained modular design will provide both high performance and flexibility in supporting multiple services.
