Building OpenMPI 1.2.9 for OpenSolaris with Studio 12

Building OpenMPI 1.29 for OpenSolaris with Studio 12

The last version of OpenMPI 1.2x is released. OpenMPI 1.29 is out and available for download from http://wwww.openmpi.org/

As I have in a previous blog, built 129rc1, this build is similar, but a big fix for OpenSolaris (as I documented in my blog) has made it into the source tree. This is great, you will find the build goes really smoothly.

Getting started

• OpenSolaris 2008.11

• OpenMPI 1.2.9

• Studio 12 compilers

• GNU utilities

OpenMPI 1.2.9 can be obtained at: http://www.openmpi.org/

For OpenSolaris, use the package manager and the opensolaris.org repository to download the Studio 12 compilers for C/C++ and GNU utilities, the repository is great and as a developer on OpenSolaris, you should get use to this tool to manage your environment, it is a fantastic addition, I use it heavily.

Building OpenMPI 1.2.9

# gzip -d openmpi-1.2.9.tar.gz

# tar xvf openmpi-1.2.9.tar

This is a basic delivery of source, it utilizes configure for the environment build. Configure will pick up the Studio compilers by setting the enviroment variables: CC, CFLAGS, CXX, CXXFLAGS, F77, FFLAGS

# export CC=/export/home/langston/COMPILER/SUNWspro/bin/cc

# export CXX=/export/home/langston/COMPILER/SUNWspro/bin/CC

# export F77=/export/home/langston/COMPILER/SUNWspro/bin/f77

With /export/home/langston/COMPILER/SUNWspro where I have Sun Studio 12 installed.

# configure –prefix=/usr/local/openmpi1.29

You can aim the prefix anywhere you like, but I'm finding that it is best to put OpenMPI is a location rather than let it default to /usr/local – I have too many version running around and I need them isolated from each other.

# gmake

Installing OpenMPI and running an example

# gmake install

Make sure you have that path in your PATH, in my case, /usr/local/openmpi1.29/bin , this will find things such as mpicc

Make sure you have LD_LIBRARY_PATH set with /usr/local/openmpi1.29/lib include

# export PATH=$PATH:/usr/local/openmpi1.29/bin

# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openmpi1.29/lib

# cd examples

langston@alpha:~/OPENMPI/openmpi-1.2.9/examples$ gmake hello_c

mpicc -g hello_c.c -o hello_c

langston@alpha:~/OPENMPI/openmpi-1.2.9/examples$ ldd hello_c

libmpi.so.0 => /usr/local/openmpi1.29/lib/libmpi.so.0

libuutil.so.1 => /lib/libuutil.so.1

libgen.so.1 => /lib/libgen.so.1

langston@alpha:~/OPENMPI/openmpi-1.2.9/examples$ orterun --mca btl tcp,self -np 2 hello_c

Hello, world, I am 0 of 2

Hello, world, I am 1 of 2

Caveats

• For Sun, a great alternative is to use ClusterTools 8, it is based on OpenMPI 1.3
