thanks Eugene for your example, it helps me a lot.I bump into one more problems lets say I have the file content as follow I have total of six files which all contain real and imaginary value. " 1.001212 1.0012121 //0th 1.001212 1.0012121 //1st 1.001212 1.0012121 //2nd 1.001212

Re: [OMPI users] Problem with openmpi and infiniband

For your runs with Open MPI over InfiniBand, try using openib,sm,self for the BTL setting, so that shared memory communications are used within a node. It would give us another datapoint to help diagnose the problem. As for other things we would need to help diagnose the problem, please follow

Re: [OMPI users] Problem with openmpi and infiniband

If the basic test run the installation is ok. So what happens when you try to run your application ? What is command line ? What is the error message ? do you run the application on the same set of machines with the same command line as IMB ? Pasha yes to both questions: the OMPI version
