Build 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 “Use Your MPI Build”

on page 2-6.

1 Unpack the M PI sources into the target file 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 mpich2-1.4.1p1

2 B uild your MPI usin g t he enable-shared option(thisisvital,asyoumust

build a shared library MPI, binary compatible with

MPICH2-1.4.1p1 for

R2013b and later). For example, the following commands build an MPI

with the

nemesis channel device and the g fork er launcher.

#./configure -prefix=/opt/mpich2/mpich2-1.4.1p1 \

--enable-shared --with-device=ch3:nemesis \

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

# make 2>&1 | t ee -a log

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

Use Your MPI Build

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

the Parallel Computing Toolbo x mpiexec scheduler working with a different

MPI build, follow these steps. Most of th ese steps are also needed if y ou w an t

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