Does anyone know of any tools for analysing parallel program performance?

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).

Thanks
