<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">We could do a better job documenting the "read-only" vs "read-write" nature of these hints...<br>
<br>
you cannot override the file system with the "romio_filesystem_type" hint, only confirm the file system is what you thought it was.<br>
<br>
you should be able to with the ROMIO_FSTYPE_FORCE environment variable.<br>
<br>
These symptoms suggest you requested quobyte support but ROMIO's configure could not find the development headers.... except ROMIO doesn't check for any development headers.<br>
<br>
Can you share with me the first few lines of ROMIO's config.log? From your build directory, that would be `<br>
head mpich/src/mpi/romio/config.log` (the whole config.log is too much... for now)<br>

might not be enough.<br>
<br>
I have a code that uses `MPI_Info_set` to, well, set infos and I can't seem to affect the fs type.<br>
<br>
First I set:<br>
<br>
export ROMIO_PRINT_HINTS=1<br>
<br>
and then in my code I added:<br>
<br>
call MPI_INFO_SET(info,"romio_filesystem_type","QUOBYTEFS:", status)<br>
<br>
but, well:<br>
<br>
key = romio_filesystem_type value = UFS: Generic ROMIO driver for all UNIX-like file systems<br>
<br>
I also tried it in lowercase as well. No joy.<br>
<br>
I've also tried:<br>
<br>
export ROMIO_FSTYPE_FORCE="QUOBYTEFS:"<br>
<br>
and:<br>
<br>
export ROMIO_FSTYPE_FORCE="quobytefs:"<br>
<br>
but in each case, it's still UFS. I do know my Infos are being seen by MPICH because if I toggled:<br>
<br>
call MPI_INFO_SET(info,"romio_cb_write","enable", status)<br>
<br>
from enable to disable, the ROMIO_PRINT_HINTS show the change.<br>

Subject: [EXTERNAL] [BULK] [mpich-discuss] How to make/run romio tests?<br>
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:

<br>
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.<br>
<br>
So, following that Quobyte page, I get to Step 10 and tried the romio tests and...I am apparently dumb. I went to my<br>
<br>
build/src/mpi/romio/test<br>
<br>
directory and I see 'runtests' there, but:<br>
<br>
> ./runtests<br>
make: *** No rule to make target 'default'. Stop.<br>
<br>
I also tried with -fname and:<br>
<br>
> ./runtests -fname=quobyte:test_mpi_file<br>
./runtests: line 90: [quobyte:test_mpi_file: command not found<br>
make: *** No rule to make target 'default'. Stop.<br>
<br>
> ./runtests -fname=quobyte:/home/mathomp4/MPI/src/mpich-4.3.0/build-ifort-2021.13/src/mpi/romio/test/test_mpi_file<br>
./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<br>
make: *** No rule to make target 'default'. Stop.<br>
<br>
Yeah. I'm stumped. I'm guessing I've missed some simple step along the way.<br>
<br>
NOTE: I have no idea even how to use romio really, but I was hoping the tests could, well, help me figure that out.<br>
<br>
Thanks for any help,<br>
Matt<br>
