[Haskell-cafe] Execution call graph pruning

Hi, I have a call grah which contains information of the edges in the following format caller callee count (time spent by the caller) =================================== foo bar 10 100 xxx yyy 20 10 zzz yyy 10 10 (I used pintool pintool.org to generate this call graph) Now, the problem is that the graph is huge and it take a long to render using 'dot' or use any visualizing tool. Even if they render, it's too cluttered to be useful. I wanted to prune the graph in such a way that I'd have only the edges corresponding to the top 10% of the time consumers. What would be a good way to do such a thing? Has anyone written some utility that I could use? -- Regards, Kashyap
