SUMMARY:Extending MPI Correctness Benchmarking to the Fortran Language
DESCRIPTION:Yussur Mustafa Oraji, Alexander Hück, and Christian Bischof (T
 echnical University of Darmstadt)\n\nMPI correctness benchmarks are used t
 o evaluate the implementation quality of MPI correctness tools on a standa
 rdized set of tests.\nHowever, existing correctness benchmarks are limited
  to C, neglecting support for Fortran, the only other language which the M
 PI standard supports.\nConsequently, past evaluations of correctness tools
  were focused solely on C although some of them support error-checking of 
 Fortran MPI codes.\nTo alleviate this, we port the test generation logic o
 f the most recently introduced MPI correctness benchmark MPI-BugBench to F
 ortran.\nWe explore language-specific porting challenges and perform a com
 parative accuracy evaluation of the dynamic MPI correctness tool MUST on b
 oth C and Fortran.\nOur results show that MUST's accuracy is largely consi
 stent across languages, with a notable exception in type checking due to a
  required software dependency not supporting Fortran.\nAdditionally, we un
 covered bugs in both the OpenMPI Fortran bindings,\nand the MPI-BugBench t
 est case generator.\n\nTag: Debugging & Correctness Tools, HPC Software &
