Subject: Re: [OMPI users] bind-to core warning even with numactl
From: Saliya Ekanayake (esaliya_at_[hidden])

I actually did a rebuild and install. Is there a quick test to see if these
were picked up correctly. I checked OMPI_INFO and can see numaif.h has been
founded. Is this the correct indication?

I'll check the link and send details by tomorrow as our clusters are on
maintenance today.

Thank you,
Saliya
