Thanks, Jeff!

But there's one problem. Suppose I'm on rank 1 and I want to know the host name of rank 2, then using this function I can only know my own host name. I hope that I can know others' host names...

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
