Hi Joshua, I represent Intel MPI team here. libtvmpi.so should be part of all IMPI 2018 releases.

I'm going to double check the situation. Thanks for the heads up. BR, Dmitry From: mpiwg-tools <[email protected]> On Behalf Of Josh Cottingham via mpiwg-tools Sent: Tuesday, November 24, 2020 7:36 PM To: [email protected] Cc: Josh Cottingham <[email protected]>; Kevin Mooney <[email protected]> Subject: [mpiwg-tools] Intel MPI MQD support Hey everyone, Is anyone within this group a part of the Intel MPI team or know a contact who works in that team? I was wondering if Message Queue Debugging support has been officially removed from Intel MPI? They've removed references to Message Queue Debugging from their user guide and no longer ship the message queue library libtvmpi.so. We cannot seem to find the find the mqs_ API anywhere (checked with Intel MPI newer than 2018.2).
