Hi FluTE devs,

I'm currently trying to get mpiflute working on my local machine (before I try to get it running on a cluster) with either MPICH or Intel MPI, but when I compile with either (editing the makefile appropriately) and try to run with config-usa, the R0 calculation and interpolated beta are calculated correctly, then the application terminates with a segmentation fault, propagating the std::bad_alloc exception to stderr when run with one MPI process (the exception never makes it to stderr when run with more than one MPI process). Does this config file just require a lot of RAM to run? I should have about 8GB of RAM available when running, so I'd be surprised if there isn't something else going on.

I edited my makefile to use the lines
MPICFLAGS = -Wall -I/opt/intel/compilers_and_libraries_2020.0.166/linux/mpi/intel64/include -pthread -DDSFMT_MEXP=19937
MPILDFLAGS = -L. -L/opt/intel/compilers_and_libraries_2020.0.166/linux/mpi/intel64/lib -lm -lmpi_ilp64 -lutil -lnsl -ldl -lrt

Is that correct? And if so, am I just running out of memory (which isn't a problem, since I have access to a cluster for real runs), or is there something else I'm doing wrong? Thanks!

Hi @dlchao, figured I'd let you know that I updated the MPI calls in mpiflute to be correct for MPI 3.0 (which deprecates the C++ API, among other minor changes) in my local version. It appears that I don't have permission to push to a development branch, but if you're interested in the updated mpiflute code, let me know and we can sort out a pull request.
