SUMMARY:Understanding Simultaneous Impact of Network QoS and Power on HPC 
 Application Performance
DESCRIPTION:Tapasya Patki (Lawrence Livermore National Laboratory), Emre A
 tes and Ayse Coskun (Boston University), and Jayaraman J. Thiagarajan (Law
 rence Livermore National Laboratory)\n\nWith the growing complexity of hig
 h performance computing (HPC) systems, application performance variation h
 as increased enough to disrupt the overall throughput of the systems. Such
  performance variation is expected to worsen in the future, when job sched
 ulers will have to manage flow resources such as power, network and I/O in
  addition to traditional resources such as nodes and memory. In this work,
  we study the simultaneous impact of inter-job interference, Infiniband se
 rvice levels, and power capping on different applications in a controlled 
 experimental setup, with the goal of understanding the range of performanc
 e variation as well as potential mitigation strategies.\n\nTag: Exascale, 
 Hot Topics, Reproducibility, Scientific Computing\n\nRegistration Category
 : Workshop Reg Pass\n\nSession Chairs: Walid Keyrouz (National Institute o
 f Standards and Technology (NIST)) and Michael V. Mascagni (Florida State 
 University, National Institute of Standards and Technology (NIST))\n\n
