<div dir="ltr">Hi Lee,<div>well, it seems that Dacapo wants to convert the Callgraph to Dot and CSV file and does this in-memory. This is not a good idea, since this graph in particular seems to large. Try to optimize the Dacapo code that every part of String gets written out to a file directly (without buiilding it in memory before). Alternatively, give it more memory than 12 Gigs.</div><div><br></div><div>Look into the implementation of <span style="font-size:12.8px">nz.ac.massey.soot.callgraph.</span><wbr style="font-size:12.8px"><span style="font-size:12.8px">SootUtil.convertToDotAndCSV</span></div><div><br></div><div>Cheers,</div><div>Marc</div></div><div class="gmail_extra"><br><div class="gmail_quote">2017-01-30 23:19 GMT+01:00 Li Sui <span dir="ltr"><<a href="mailto:leesui0207@gmail.com" target="_blank">leesui0207@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-size:small">Hi there</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">I am running soot to generate call-graph for Dacapo.
