SUMMARY:Performance and Energy Analysis
DESCRIPTION:Energy Efficiency Modeling of Parallel Applications\n\nEnergy 
 efficiency has become increasingly important in high performance computing
  (HPC), as power constraints and costs escalate. Workload and system chara
 cteristics form a complex optimization search space in which optimal setti
 ngs for energy efficiency and performance often diverge. Thus, we must ...

 nA Parallelism Profiler with What-If Analyses for OpenMP Programs\n\nThis 
 paper proposes OMP-WHIP, a profiler that measures inherent parallelism in 
 the program for a given input and provides what-if analyses to estimate im
 provements in parallelism. We propose a novel OpenMP series parallel graph
  representation (OSPG) that precisely captures series-parallel relations .

 ability on the Xeon Platinum 8160 Processor\n\nDuring initial testing of a
  large cluster equipped with Xeon Platinum 8160 processors, we observed in
 frequent, but significant, performance drops in HPL benchmark results. The
  variability was seen in both single node and multi-node runs, with approx
 imately 0.4% of results more than 10% slower than t...\n\n\nJohn D. McCalp
