"yum install openmpi openmpi-devel"
but when i am trying to compile my code with command
"mpicc -o hello hello.c"
it says mpicc command not found
please help me getting started with mpi.

The mpicc command (actually it is a link to opal_wrapper) doesn't reside in a standard directory and for this reason it's not included in your PATH. You have to add the directory to your PATH, e.g.

Code:

export PATH=/usr/lib64/openmpi/bin:$PATH

or give the full path on the command line:

Code:

/usr/lib64/openmpi/bin/mpicc -o hello hello.c

Hope this helps.

@coluxic :
I added the path too but its still not working for me.

Mine was only an example, your path might be different. Please verify it by

Code:

rpm -ql openmpi-devel | grep 'bin/mpicc$'

which OS are you running on, anyway?

The full PATH can be used too, like this example :

/usr/lib/openmpi/bin/mpicc -o hello hello.c

I am using fedora 17

Ok. And what is the output of the previously suggested command?

Code:

rpm -ql openmpi-devel | grep 'bin/mpicc$'

Nothing shown up by the command "rpm -ql openmpi-devel | grep 'bin/mpicc$'"
But the problem is resolved as suggested in the tutorial site (suggested me install "mpich2")
