[Paraview-developers] problems with >64 pvservers

[Biddiscombe, John A.]

I was doing some scalability runs last week  - actually redoing some old ones and I found that if I use >64 pvservers, although the server says "client connected", the client locks up and never returns. Setting breakpoints shows it to be in some low level nvidia driver (windows client) which didn't make a lot of sense to me.

However I had similar problems when running on a remote cluster with a vnc session and a linux compiled client.

I tried recompiling paraview with all plugins disabled, but the problem persists. I do have a couple of my own patches applied, but I do not suspect them to be the problem.

I'm using pv3.98 master from about 2 weeks ago and can do a pull - but I doubt it'll make a difference (I had this problem before and pulled in the hope it'd be fixed). I'm currently suspecting the new memory inspector as a possible cause of hang around startup - but this is based on no evidence, so take it with a pinch of salt.

Is anyone using a recent pvserver on large node counts? Can you confirm that it is working as expected?

Has anyone else had trouble?

Thanks

JB
