Hmm, interesting !
For GETs, I think the only reason the line degrades a only slightly
after 5 nodes is that the chance of hitting youself (therefore no
communication needed) decreases with increasing cluster size. I wonder
how this would line would look like on cluster sizes of 30+ ...
+1
Did you have the chance to finish the jgroups plugin for Radargun? Very curious to see the
results between (ISPN+evenDist) vs (jgroups with numOwners/cluster size local calls).
For PUTs, the degradation is more pronounced. I assume this is with
numOwners=2 ?
yes
In that case, the chance of hitting yourself is twice of
that for GETs.
indeed.
Can you re-run this test with numOwners=1 ? I guess we should then
see a
similar line for PUTs than for GETs.
indeed, it's very similar! Results
attached.
I assume you're sending instructions on how to run this ideal distribution ?
