"MPICH2 is a high-performance and widely portable implementation of the Message Passing Interface (MPI) standard (both MPI-1 and MPI-2)
The goals of MPICH2 are:
mpich2-1.3.1.tar.gz source code can be downloaded from http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads
tar -xvzf mpich2-1.3.1.tar.gz cd mpich2-1.3.1
Set the environment for the code:
env CC=pgcc FC=pgfortran F77=pgfortran CXX=pgcpp CFLAGS=-fast FCFLAGS=-fast FFLAGS=-fast \ CXXFLAGS=-fast ./configure --prefix=/opt/pgi/linux86-64/2011/mpi/mpich2 >& configure.log
Build the code:
make >& make.log
Install the code:
sudo su make install make install-examples
After you have successfully installed the MPICH2 library you will need to create a "mpd.hosts" file with the list of your cluster's host names. For more information about mpd.hosts, please refer to MPICH2 manual (doc/installguide/install.pdf).
To test your MPICH2 installation, first make sure that the MPICH2 install's bin directory is in your PATH environment variable. Then run mpdboot to start up mpd daemon. Next run mpdtrace to print out a list of hosts. Now, run program in examples directory
mpd& mpdtrace mpirun -np 2 /opt/pgi/linux86-64/2011/mpi/mpich2/examples/cpi
The PGI graphical MPI-parallel debugger, PGDBG, is a powerful tool for assisting in the challenging task of debugging an MPI application. PGDBG is designed to work with MPICH2 and allows you precise control over all your MPI processes. More information about PGDBG can be found at PGDBG product page. MPICH2 is not currently configured to support PGDBG. To use PGDBG with MPICH2, you must install MPICH2 from PGI CDK® package. PGI CDK has modified MPICH2 scripts to support PGDBG. To run with PGDBG, using following command:
mpiexec -pgi -np 3 myapp.out
Note: You must have a PGI CDK license in order to use PGDBG with MPICH2. For more information about obtaining a PGI CDK license, please contact PGI Sales.
