[OMPI users] Need help in setting up openmpi on multiple clusters

[gaurav gupta]

Hi,

I am new to mpi programming and openmpi. I have installed openmpi and run
several sample programmes on single machine. But while running on several
nodes it is showing errors.

I have configured openmpi and automated login to all nodes with user mpi.
Now on master i tried to run by "mpiexec -np 4 -host n1,n2,n3,n4 a.out"
where n1,n2,n3 and n4 are four nodes on which i have enabled automatic
login. Now I am getting error :

Failed to find the following executable:

Host:   server1.tm.local
Executable: a.out

Cannot continue.

Now my problem is this should I copy this executable to all nodes ??? If yes
then how will it work, because I am not expecting any value from user all
parameters are generated in a.out itself.

Please help me out what is the problem here and what should i do.

Thanks in advance.

[OMPI users] How to know which task on which node

[gaurav gupta]

Hello,

I want to know that which task is running on which node. Is there any way to
know this.
Is there any profiling tool provided along with openmpi to calculate time
taken in various steps.
