SUMMARY:RMARaceBench:  A Microbenchmark Suite to Evaluate Race Detection T
 ools for RMA Programs
DESCRIPTION:Simon Schwitanski, Joachim Jenke, Sven Klotz, and Matthias S. 
 Müller (Chair for High-Performance Computing, IT Center, RWTH Aachen Unive
 rsity)\n\nParallel programming models with Remote Memory Access (RMA), suc
 h as MPI RMA, OpenSHMEM, and GASPI, allow processes to modify the memory o
 f other processes directly.  Special care is needed to avoid concurrent co
 nflicting accesses that lead to data races across processes with undefined
  behavior. Although only some tools exist that can detect RMA races, there
  needs to be a possibility to compare their effectiveness systematically. 
 We present RMARaceBench, a microbenchmark suite, to evaluate the detection
  capabilities of current and future RMA race detection tools for MPI RMA, 
 OpenSHMEM, and GASPI. It consists of about 100 synthetic race test cases f
 or each programming model, aiming to cover all possible race scenarios. Us
 ing RMARaceBench, we evaluate two MPI RMA race detectors implemented in th
 e correctness tools PARCOACH and MUST. The evaluation shows that RMARaceBe
 nch can pinpoint the strengths and weaknesses of RMA race detectors.\n\nTa
