All, I'm trying to do some tests on a Quobyte system and we've seen confusing file write timings with Intel MPI and Open MPI. So, a bit of googling seeing if some MPI stack has a mention of Quobyte turns up: https://urldefense.us/v3/__https://www.quobyte.com/blog/quobyte-mpi-io-suppo... and, yep, quobyte seems to be in MPICH! I grabbed MPICH 4.3.0 and built it (with one bug fix[1]) and well, it seems to run Hello World. So, following that Quobyte page, I get to Step 10 and tried the romio tests and...I am apparently dumb. I went to my build/src/mpi/romio/test directory and I see 'runtests' there, but:
./runtests make: *** No rule to make target 'default'. Stop.
I also tried with -fname and:
./runtests -fname=quobyte:test_mpi_file ./runtests: line 90: [quobyte:test_mpi_file: command not found make: *** No rule to make target 'default'. Stop.
./runtests -fname=quobyte:/home/mathomp4/MPI/src/mpich-4.3.0/build-ifort-2021.13/src/mpi/romio/test/test_mpi_file ./runtests: line 90: [quobyte:/home/mathomp4/MPI/src/mpich-4.3.0/build-ifort-2021.13/src/mpi/romio/test/test_mpi_file: No such file or directory make: *** No rule to make target 'default'. Stop.
Yeah. I'm stumped. I'm guessing I've missed some simple step along the way. NOTE: I have no idea even how to use romio really, but I was hoping the tests could, well, help me figure that out.
