Building MPI

To use an MPI build that differs from the one provided with Parallel

Computing Toolbox, this stage outlines the steps for creating an MPI build.

If you already have an alternative MPI build, proceed to “Using Your MPI

Build” on page 2-6.

1 Unpack the MPI sources into the target Þle system on your machine. For

example, suppose you have downloaded mpich2-distro.tgz and want

to unpack it into /opt for building:

# cd /opt

# mkdir mpich2 && cd mpich2

# tar zxvf path/to/mpich2-distro.tgz

# cd mpich2-1.0.8

2 Build your MPI using the enable-sharedlibs option (this is vital, as you

must build a shared library MPI, binary compatible with MPICH2-1.0.8

for R2009b and later). For example, the following commands build an MPI

with the nemesis channel device and the gforker launcher.

# ./configure -prefix=/opt/mpich2/mpich2-1.0.8 \

--enable-sharedlibs=gcc \

--with-device=ch3:nemesis \

--with-pm=gforker 2>&1 | tee log

# make 2>&1 | tee -a log

# make install 2>&1 | tee -a log

Using Your MPI Build

When your MPI build is ready, this stage highlights the steps to use it. To get

the Parallel Computing Toolbox mpiexec scheduler working with a different

MPI build, follow these steps. Most of these steps are also needed if you want

to use a different MPI build with third party-schedulers (LSF, generic).
