Subject: Is there a working cache for path record and lids etc for librdmacm?
Date: Tue, 17 Nov 2020 02:57:57 +0000 (UTC) [thread overview]
Message-ID: <alpine.DEB.2.22.394.2011170253150.206345@www.lameter.com> (raw)
We have a large number of apps running on the same host that are all
sending to the same set of hosts. Lots of requests for address resolution
are going to the SM and for a large set of hosts this can become too much
for the SM.
Is there something that can locally cache the results of the SM queries to
avoid additional requests?
We have tried IBACM but the address resolution does not work on it. It is
unable to complete a request for any address resolution and leaves kernel
threads that never terminate instead.
