[mvapich-discuss] Seg fault on remote node

[Trevor Gale]

Hello all,

I’m experiencing a weird error where when I run an application across multiple nodes it always throws seg fault. To make sure it wasn’t the application, I’m running osu_allgather micro-benchmark. I’ve also confirmed that mvapich is running correctly on both of the nodes I’m testing it with by running the benchmark on each node individually. 

Here is the output I get when I run it on both nodes:
 

It appears to be something wrong with my configuration of mvapich or the network. I am using IPoIB over Infiniband QDR. Does anyone have any idea what might be causing this output?

Thanks,
Trevor
