Hi, since more than 2 weeks that the master branch of mpich is still and it can be reproduced with a simple "make test" after a fresh installation of PETSc... Is anyone testing it? Is it supposed to be working? Just tell me if I should "follow" another mpich branch please. Thanks, Eric On 14/03/18 03:35 AM, Eric Chamberland wrote:

Hi,

fwiw, the actual mpich/master branch doesn't passes the PETSc "make test" after a fresh installation... It hangs just afer the 1 MPI process test, meaning it is locked into the 2 process test:

make PETSC_DIR=/pmi/cmpbib/compilation_BIB_dernier_mpich/COMPILE_AUTO/mpich-3.x-debug/petsc-3.8.3-debug PETSC_ARCH=arch-linux2-c-debug test Running test examples to verify correct installation Using PETSC_DIR=/pmi/cmpbib/compilation_BIB_dernier_mpich/COMPILE_AUTO/mpich-3.x-debug/petsc-3.8.3-debug and PETSC_ARCH=arch-linux2-c-debug C/C++ example src/snes/examples/tutorials/ex19 run successfully with 1 MPI process

^Cmakefile:151: recipe for target 'test' failed make: [test] Interrupt (ignored)

thanks,

Eric

Hi,

each night we are testing mpich/master with our petsc-based code. I don't know if PETSc team is doing the same thing with mpich/master? (Maybe it is a good idea?)

Everything was fine (except the issue https://github.com/pmodels/mpich/issues/2892) up to commit 7b8d64debd, but since commit mpich:a8a2b30fd21), I have a segfault on a any parallel nightly test.

For example, a 2 process test ends at almost different execution points:

Have some other users (PETSc users?) reported problem?

Thanks,
