ITAC error during trace collection

915 Views

Hi all,

I am trying to collect tracing info for my Intel MPI job. For relatively small number of processes (around 300) the run hangs or I receive the following error message:

UCM connect: REQ RETRIES EXHAUSTED: 0x570 32c43 0xed -> 0x544 3f3a4 0xbbdd

How can I debug this error?

Best,

Igor
