Hi,

Hi Kazu,

Andreas - want me to go ahead and get you some hardware to test Ben's patch in the mean time? This way we'll at least not leave it hanging until the last moment...

I will also try this with two 20-core machines connected 10G on Monday.

I measured the performace of GHC head, 7.8.3 and 7.8.3 + Ben's patch set.

Server: witty 8080 -r -a -s +RTS -N<n> *1

Have you noticed that witty will sometimes terminate (with exit code 0) spontaneously during a run? This seems to happen more often with higher core counts. I've seen this both with and without my patch (based on master as of earlier today). Cheers, - Ben
