Yes, I know. Sorry I might not have articulated myself fully earlier.
Currently if I run configure as:
$ ./configure --prefix=/curc/tools/x_86_64/rh6/openmpi/1.8.3/intel/13.0.0 \
--with-threads=posix --enable-mpi-thread-multiple \
--with-pmi=/curc/slurm/slurm/current/ --with-slurm
I get the following error:
--- MCA component common:pmi (m4 configuration macro)
checking for MCA component common:pmi compile mode... dso
checking if user requested PMI support... yes
checking if PMI or PMI2 headers installed... Slurm PMI headers found
checking for PMI2_Init in -lpmi2... no
checking for PMI2_Init in -lpmi... no
checking for PMI_Init in -lpmi... no
checking PMI2 and/or PMI support enabled... no
configure: WARNING: PMI support requested (via --with-pmi) but not found.
configure: error: Aborting.
As the test in config/opal_check_pmi.m4 contains:
[AS_IF([test -d "$with_pmi/lib64"],
[opal_check_pmi_$1_LDFLAGS="-L$with_pmi/lib64"
opal_pmi_rpath="$with_pmi/lib64"],
[opal_check_pmi_$1_LDFLAGS="-L$with_pmi/lib"
opal_pmi_rpath="$with_pmi/lib”])
And in our SLURM installation directory:
$ ls /curc/slurm/slurm/current/lib64/
perl5
$ ls /curc/slurm/slurm/current/lib/
libpmi.a libpmi.so.0 libslurmdb.a libslurmdb.so.27 libslurm.so
slurm
libpmi.la libpmi.so.0.0.0 libslurmdb.la libslurmdb.so.27.0.0 libslurm.so.27
libpmi.so libslurm.a libslurmdb.so libslurm.la
libslurm.so.27.0.0
So the patch I am providing checks for the actual libpmi.so file, by
1) replacing the test -d with a test -f
2) appending the file we are looking for (libpmi.so)
You do bring up an interesting point, I didn’t think of. If it is checking for
libpmi2.so, that can be accounted for by adding another 2 test and run-if-true
results to the AS_IF macro. If you deem my patch worthwhile, I am happy to
modify it to meet this criteria.
