Abstract

BGQ_FIXES (Doc Number=3447): Blue Gene/Q V1R2M1 eFix027 available A new eFix for Blue Gene/Q V1R2M1 is available at the Blue Gene/Q download website in offering V1R2M1 eFix for Blue Gene/Q Programs .
eFix for messaging-totalview-fortran-commsplit (efix_bgq_v1r2m1_027)
This efix resolves these problems:
Problem 1: ---------- The totalview debugger library was incorrectly named. Applied a fix from the mpich community to resolve.
=> https://trac.mpich.org/projects/mpich/ticket/1965
=> https://trac.mpich.org/projects/mpich/changeset/6442aa7b82322906126b5b7c12b6481eeb4a0ae7
Problem 2: ---------- The f77 mpi wrapper scripts were incorrectly referencing the f90 mpich library.
Changed the scripts to use the correct f77 mpich library.
Problem 3: ---------- The xl compiler mpi wrapper scripts were incorrectly using gfortran mod files.
Fix the scripts to instead use the xlf generated mod files.
Problem 4: ---------- The hang in comm_split was caused by incorrectly handling the case of running out of MU resources in creating class routes during geometry create. Two fixes were added:
- Retry for a specific number of tries to make sure that the resources are free and then exit gracefully (i.e. not use optimized geometries). - Release mutex on exit. Doc number: 3447 Published date: 20140314
