MPICH2 Configuration in UBUNTU 10.10 Meveric Meerkat

Step 1: Go to System->About Ubuntu check the version, whether it is mentioned above or not??

Step 2:

Go to the following link and download the MPICH2 package

http://www.mcs.anl.gov/research/projects/mpich2/downloads/tarballs/1.3a2/mpich2-1.3a2.tar.gz

change user to root or user super user privilege on every command

sudo -i

cd to the package location :

#cd /location

Then uncompress the package

# tar xzvf filename.tar.gz

go to the 'package root' :

# cd filename

then configure environment

#./configure

 If you are getting the error regarding the gcc compiler or c++ compiler then write following command in terminal

sudo apt-get install build-essential

compile the package

# make

install the compiled package

#make install

Another small thing to do to start the mpich2 daemon:

then, make the user specific configuration file:

cd $HOME

touch .mpd.conf
chmod 600 .mpd.conf
gedit .mpd.conf

add the following line to the newly created .mpd.conf file

MPD_SECRETWORD=secret

now do the following steps

type the command mpd or mpd &

now create the example file to run

#include

#include "mpi.h"

int main(int argc,char** argv)

{

int p_id,size;

MPI_Init(&argc,&argv);

MPI_Comm_rank(MPI_COMM_WORLD,&p_id);

MPI_Comm_size(MPI_COMM_WORLD,&size);

printf("Hello from prpcess %d of %d \n",p_id,size);

MPI_Finalize();

return 0;

}

save this in a 'hpc.c' file.

compile the application

mpicc hpc.c -o hello

change access to executable of the output file

chmod +x ./hello

run the application

mpirun -np 4 ./hello
