FastPath 2015 - overview

FastPath 2015

Fourth International Workshop on Performance
Analysis of Workload Optimized Systems


March 29, 2015 - Philadelphia, PA
In conjunction with ISPASS 2015


The preliminary program is available here


The goal of FastPath is to bring together researchers and practitioners involved in cross-stack hardware/software performance analysis, modeling, and evaluation of workload optimized systems. With microprocessor clock speeds being held constant, optimizing systems around specific workloads is an increasingly attractive means to improve performance. More precisely, workload optimized systems have hardware and/or software specifically designed to run well for a particular application or application class. The types and components of workload optimized systems vary, but a partial list includes traditional CPUs assisted with accelerators (ASICs, FPGAs, GPUs), memory accelerators, I/O accelerators, hybrid systems, converged infrastructure, and IT appliances. The importance of workload optimized systems is seen in their ubiquitous deployment in diverse systems from cellphones to tablets to routers to game machines to Top500 supercomputers. Prominent commercial examples of workload optimized systems include IBM DataPower, IBM Purescale Application System, IBM Watson, Oracle Exadata, and HP Moonshot Servers. Exploiting CPU savings and speed-ups offered by workload optimized systems for application level performance improvement poses several cross stack hardware and software challenges.  These include developing alternate programming models to exploit massive parallelism offered by accelerators, designing low-latency, high-throughput H/W-S/W interfaces, developing techniques to efficiently map processing logic on hardware, and cross system stack performance optimization and tuning.  Emerging infrastructure supporting big data analytics, cognitive computing, large-scale machine learning, mobile computing, and internet-of-things, further exemplify workload optimized design at large.


FastPath seeks to facilitate the exchange of ideas on performance analysis and evaluation of workload optimized systems and seeks papers on a wide range of topics including, but not limited to:

  • Workload characterization and profiling
  • Industrial experiences
  • GPUs, FPGAs, ASIC accelerators
  • Memory, I/O, storage, network accelerators
  • Hardware/software co-design
  • Workload optimized servers
  • Hybrid/heterogeneous systems
  • Measurements and experimentation
  • Analytical techniques
  • Performance modeling and prediction
  • Performance tooling and optimization
  • Programming models for workload optimized systems
  • Runtime management systems
  • Workload scheduling and orchestration
  • Workload optimized clusters in cloud
  • Big data analytics systems
  • Large-scale machine learning systems
  • Intelligent/cognitive systems
  • Mobile computing systems
  • Converged/integrated infrastructure
  • Workload optimized systems from specific domains, e.g., financial, biological, education, commerce, healthcare



Prospective authors must submit a 2-4 page extended abstract electronically by the submission deadline. Authors of selected abstracts will be invited to give a 30-min presentation at the workshop.
