Hi, I am trying to profile some code with Tau on a single node with 12 threads on an X86 machine. I am able to view the PAPI counter results with paraprof without any problems. However, when I follow these directions (https://www.cs.uoregon.edu/research/tau/docs/old/bk01ch04s03.html) , then try to open the tau.slog2 file (which is 814MB) with Jumpshot to view the timeline, I am only able to view the main and legend windows, then I get a bunch of errors saying it’s out of memory in the Java heap (see errors below). When I run Jumpshot, I am grabbing a whole node that has 24 GB of memory available, which I think should be enough. About how much memory should I expect Jumpshot to require on a slog2 file that is just under 1 GB? Thank you, Eileen Martin Here’s an example of the errors I am getting, in case you recognize these (I get the same errors for other threads): slog_ins.tZoomFtr = 2.0 Exception in thread "Thread-1" java.lang.OutOfMemoryError: Java heap space at base.drawable.InfoBox.resolveCategory(InfoBox.java:103) at logformat.slog2.BufForDrawables.readObject(BufForDrawables.java:249) at logformat.slog2.input.TreeNode.readObject(TreeNode.java:137) at logformat.slog2.input.TreeNode.<init>(TreeNode.java:130) at logformat.slog2.input.InputLog.readTreeNode(InputLog.java:327) at logformat.slog2.input.TreeTrunk.growChildren(TreeTrunk.java:138) at logformat.slog2.input.TreeTrunk.growChildren(TreeTrunk.java:147) at logformat.slog2.input.TreeTrunk.growChildren(TreeTrunk.java:147) at logformat.slog2.input.TreeTrunk.growInTreeWindow(TreeTrunk.java:110) at viewer.timelines.CanvasTimeline.<init>(CanvasTimeline.java:113) at viewer.timelines.TimelinePanel.<init>(TimelinePanel.java:167) at viewer.timelines.TimelineFrame.<init>(TimelineFrame.java:37) at viewer.first.LogFileOperations$1.construct(LogFileOperations.java:238) at viewer.common.SwingWorker$2.run(SwingWorker.java:109) at java.lang.Thread.run(Thread.java:682)
