Hello,
The below FAQ lists instructions on how to use a relocated Open MPI
installation:
http://www.open-mpi.org/faq/?category=building#installdirs
On Solaris, OPAL_PREFIX and friends (documented in the FAQ) work for
me with both MPI (hello_c) and non-MPI (hostname) programs. On Linux,
I can only get the non-MPI case to work. Here are the environment
variables I am setting:
$ cat setenv_opal_prefix.csh
set opal_prefix = "/opt/openmpi-relocated"
setenv OPAL_PREFIX $opal_prefix
setenv OPAL_BINDIR $opal_prefix/bin
setenv OPAL_SBINDIR $opal_prefix/sbin
setenv OPAL_DATAROOTDIR $opal_prefix/share
setenv OPAL_SYSCONFDIR $opal_prefix/etc
setenv OPAL_SHAREDSTATEDIR $opal_prefix/com
setenv OPAL_LOCALSTATEDIR $opal_prefix/var
setenv OPAL_LIBDIR $opal_prefix/lib
setenv OPAL_INCLUDEDIR $opal_prefix/include
setenv OPAL_INFODIR $opal_prefix/info
setenv OPAL_MANDIR $opal_prefix/man
setenv PATH $opal_prefix/bin:$PATH
setenv LD_LIBRARY_PATH $opal_prefix/lib:$opal_prefix/lib/64
Here is the error I get:
$ mpirun -np 2 hello_c
--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
opal_carto_base_select failed
--> Returned value -13 instead of OPAL_SUCCESS
--------------------------------------------------------------------------
[burl-ct-v20z-0:27737] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file runtime/orte_init.c at line 77
Any ideas on what's going on?
Thanks,
Ethan
