Try MPI_Get_processor_name. Jeff On Thursday, March 12, 2015, YANG Fan <[email protected]> wrote:

Hi,

To run an MPI program on a cluster I need to pass the host file as a parameter. However, how can I know that what host name does a specific rank correspond to? Or how can I access the host file inside my MPI program? Thanks!

Best Regards, Fan
