<div dir="ltr">Hi Dominic,<br><br><div>A few years ago we wrote a program for analysing DPH runs, dph-event-seer. It provides a few general analyses like percent of time with N threads running, time between wake-ups etc. You might find it interesting, but I haven't actually looked at ghc-events-analyse, so I don't know what it provides.<div><br><div>I'm sorry, but to compile it without DPH you'd have to modify it to remove DphOps*.</div><div><div><br></div><div><a href="https://github.com/ghc/packages-dph/blob/master/dph-event-seer/src/Main.hs">https://github.com/ghc/packages-dph/blob/master/dph-event-seer/src/Main.hs</a><br></div><div><br></div><div>Amos</div></div></div></div></div><br><div class="gmail_quote">On Tue, 31 Mar 2015 at 04:38 Dominic Steinitz <<a href="mailto:dominic@steinitz.org">dominic@steinitz.org</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Does anyone know of any tools for analysing parallel program performance?<br>

I am trying to use threadscope but it keeps crashing with my 100M log file and ghc-events-analyze is not going to help as I have many hundreds of threads all carrying out the same computation. I think I’d like a library that would allow me to construct my own analyses rather than display them via GTK. There is ghc-events but that seems to be just for parsing the logs and I couldn’t find anything that used it in the way I would like to (apart from threadscope and ghc-events-analyze of course).<br>

Thanks<br>
