Hi,

Clarifications:
- I have downloaded pre-build OpenMPI_v1..5.3-x64 from open-mpi.org
- installed it on Window 7
- and then copied OpenMPI_v1..5.3-x64 directory from Windows 7 to
Windows Server 2008 into different directory and also in same
directory

Now on Windows Server 2008, I am observing these errors...

c:\ompi_tests\win64>mpirun mar_f_i_op.exe
[nbld-w08:04820] [[30632,0],0] ORTE_ERROR_LOG: Error in file
..\..\..\openmpi-1.5.3\orte\mca\ras\base\ras_base_allocate.c at line
147
[nbld-w08:04820] [[30632,0],0] ORTE_ERROR_LOG: Error in file
..\..\..\openmpi-1.5.3\orte\mca\plm\base\plm_base_launch_support.c at

..\..\..\openmpi-1.5.3\orte\mca\plm\ccp\plm_ccp_module.c at line 186

As suggested, I tried with following but nothing worked...
- copied to the same directory as it was in previous machine
- executed "mpirun -mca orte_headnode_name HEADNODE_NAME" and "mpirun
-mca orte_headnode_name MYHOSTNAME"
- set OPENMPI_HOME and other OPAL_* env variables as follow...

set OPENMPI_HOME=C:\MPIs\OpenMPI_v1.5.3-x64
set OPAL_PREFIX=C:\MPIs\OpenMPI_v1.5.3-x64
set OPAL_EXEC_PREFIX=C:\MPIs\OpenMPI_v1.5.3-x64
set OPAL_BINDIR=C:\MPIs\OpenMPI_v1.5.3-x64\bin
set OPAL_SBINDIR=C:\MPIs\OpenMPI_v1.5.3-x64\sbin
set OPAL_LIBEXECDIR=C:\MPIs\OpenMPI_v1.5.3-x64\libexec
set OPAL_DATAROOTDIR=C:\MPIs\OpenMPI_v1.5.3-x64\share
set OPAL_DATADIR=C:\MPIs\OpenMPI_v1.5.3-x64\share
set OPAL_SYSCONFDIR=C:\MPIs\OpenMPI_v1.5.3-x64\etc
set OPAL_LOCALSTATEDIR=C:\MPIs\OpenMPI_v1.5.3-x64\etc
set OPAL_LIBDIR=C:\MPIs\OpenMPI_v1.5.3-x64\lib
set OPAL_INCLUDEDIR=C:\MPIs\OpenMPI_v1.5.3-x64\include
set OPAL_INFODIR=C:\MPIs\OpenMPI_v1.5.3-x64\share\info
set OPAL_MANDIR=C:\MPIs\OpenMPI_v1.5.3-x64\share\man
set OPAL_PKGDATADIR=C:\MPIs\OpenMPI_v1.5.3-x64\share\openmpi
set OPAL_PKGLIBDIR=C:\MPIs\OpenMPI_v1.5.3-x64\lib\openmpi
set OPAL_PKGINCLUDEDIR=C:\MPIs\OpenMPI_v1.5.3-x64\include\openmpi

Please correct if I missed any other env variable.

Thank you.

In 1.5.3, a overall env "OPENMPI_HOME" will do the work.

If you build OMPI with a --prefix of /foo, but then move it to /bar, various things may not work (like finding help messages, etc.) unless you set the OMPI/OPAL environment variables that tell OMPI where the files are actually located.
