Dear Slurm Developers mailing list, When calling the “srun” command, is there any way to specify the desired network interface? Our network is a mix of ethernet and inifiniband, such that only a subset of the nodes have an infiniband interface. When using “mpirun” we can specify “-iface ib0”, but there does not appear to be a similar option for “srun”. Although we can successfully run our applications with “srun”, we can see from “iftop” that the application is communicating purely through the ethernet interface.
Once again, I appreciate any help or guidance that you can give me! Regards, Seb =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Dr. Sebastian D.
