I have the following, rather unusual, scenario...
I have a program running with OpenMP on a multicore computer. At one point
in the program, I want to use an external package that is written to
exploit MPI, not OpenMP, parallelism. So a (rather awkward) solution could
be to launch the program in
Related to this or not, I also get a hang on MVAPICH2 2.3 compiled with GCC
8.2, but on t_filters_parallel, not t_mpi. With that combo, though, I get a
segfault, or at least a message about one. It’s only “Alarm clock” on the GCC
4.8 with OpenMPI 3.1.3 combo. It also happens at the ~20 minute
Yes, I was talking about the same thing, although for me it was not t_mpi, but
t_shapesame that was hanging. It might be an indication of the same issue
however.

Same thing, OpenMPI 3.1.3, GCC 4.8.5, and HDF5 1.10.4 make check? Just making
sure — that makes it seem like there’s something
