Micky: A Cheaper Alternative for Selecting Cloud Instances

PROCEEDINGS 2018 IEEE 11TH INTERNATIONAL CONFERENCE ON CLOUD COMPUTING (CLOUD), pp. 409–416.

By: C. Hsu n, V. Nair n, T. Menzies n & V. Freeh n

TL;DR: A collective-optimizer is created, MICKY, that reformulates the task of finding the near-optimal cloud configuration as a multi-armed bandit problem and can achieve on average 8.6 times reduction in measurement cost as compared to the state-of-the-art method while finding near-Optimal solutions.

2017 conference paper

Trilogy: data placement to improve performance and robustness of cloud computing

2017 IEEE International Conference on Big Data (Big Data), 2442–2451.

By: C. Hsu n, V. Freeh n & F. Villanustre

TL;DR: Evaluations show that maximizing the number of unique partitions per node increases robustness to tolerate workload deviation while minimizing this number reduces storage footprint, and a surprisingly small increase in granularity is sufficient to obtain most benefits. (via Semantic Scholar)

2016 conference paper

Inside-out: Reliable performance prediction for distributed storage systems in the cloud

Proceedings of 2016 ieee 35th symposium on reliable distributed systems (srds), 127–136.

By: C. Hsu n, R. Panta*, M. Ra* & V. Freeh n

TL;DR: In-depth evaluation shows that Inside-Out is a robust solution that enables SDS to predict end-to-end performance even in challenging conditions, e.g., changes in workload, storage configuration, available cloud resources, size of the distributed storage service, and amount of interference due to multi-tenants.

2015 article

Dynamically controlling node-level parallelism in Hadoop

2015 IEEE 8TH INTERNATIONAL CONFERENCE ON CLOUD COMPUTING, pp. 309–316.

By: K. Kc n & V. Freeh*

TL;DR: This work develops an approach to dynamically change the parallelism for concurrent containers to suit an application and improves performance of MapReduce applications by as much as 28% and 60% respectively when compared to the best practice and default settings. (via Semantic Scholar)

2015 article

Evaluation of MapReduce in a large cluster

2015 IEEE 8TH INTERNATIONAL CONFERENCE ON CLOUD COMPUTING, pp. 461–468.

By: K. Kc n, C. Hsu n & V. Freeh n

TL;DR: The findings of running applications on Pivotal's Analytics Workbench, which consists of a 540-node Hadoop cluster, show that IO-intensive applications do not scale as data size increases and MapReduce applications require different amounts of parallelism and overlap to minimize completion time.

2014 chapter

Tuning Hadoop Map Slot Value Using CPU Metric

In Big Data Benchmarks, Performance Optimization, and Emerging Hardware (pp. 141–153).

By: K. Kc n & V. Freeh n

TL;DR: A low-overhead method is found to predict the best MSV using a new Hadoop counter that measures per-map task CPU utilization and shows that using a single MSV for all applications results in performance degradation up to 132 % when compared to using the bestMSV for each application.

Adaptive, transparent CPU scaling algorithms leveraging inter-node MPI communication regions

PARALLEL COMPUTING, 37(10-11), 667–683.

By: M. Lim*, V. Freeh n & D. Lowenthal*

author keywords: Power-aware computing; Message passing interface (MPI)
TL;DR: An MPI runtime system that dynamically reduces CPU frequency and voltage during communication phases in MPI programs and, without a priori knowledge, selects the CPU frequency in order to minimize energy-delay product is presented. (via Semantic Scholar)

On the Expressiveness of Return-into-libc Attacks

In Lecture Notes in Computer Science (pp. 121–141).

By: M. Tran n, M. Etheridge n, T. Bletsch n, X. Jiang n, V. Freeh n & P. Ning n

TL;DR: This paper presents a generalized R ILC attack called Turing complete RILC (TC-RILC) that allows for arbitrary computations and demonstrates that TC-R ILC satisfies formal requirements of Turing-completeness. (via Semantic Scholar)

Taming Information-Stealing Smartphone Applications (on Android)

In Trust and Trustworthy Computing (pp. 93–107).

TL;DR: A system called TISSA is developed that implements a new privacy mode in smartphones that can empower users to flexibly control in a fine-grained manner what kinds of personal information will be accessible to an application. (via Semantic Scholar)

Analyzing the energy-time trade-off in high-performance computing applications

IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, 18(6), 835–848.

By: V. Freeh n, D. Lowenthal*, F. Pan n, N. Kappiah n, R. Springer*, B. Rountree*, M. Femal n

author keywords: high-performance computing; power-aware computing
TL;DR: The results show that, for programs that have a memory or communication bottleneck, a power-scalable cluster can save significant energy with only a small time penalty, and it is possible to both consume less energy and execute in less time by increasing the number of nodes while reducing the frequency-voltage setting of each node.

2005 chapter

Safe overprovisioning: Using power limits to increase aggregate throughput

In T. N. V. B. Falsafi (Ed.), Power-aware computer systems: 4th International Workshop, PACS 2004, Portland, OR, USA, December 5, 2004 (Lecture notes in computer science; 3471) (Vol. 3471, pp. 150–164).

By: M. Femal n & V. Freeh n

Ed(s): T. B. Falsafi

TL;DR: Host-based and network-centric models are proposed to monitor and coordinate the distribution of power with the fundamental goal of increasing throughput and initial results with a synthetic benchmark indicate throughput increases of nearly 6% from a staticly assigned, power managed environment and over 30% from an unmanaged environment.
