Java on beowulf cluster?
843811Mar 15 2004 — edited Mar 22 2004We are trying to use Java (1.4.2) on a beowulf cluster. We have successfully installed it on the master node and it runs fine there. We exported the java directory to the compute nodes but we get a JVM error upon startup (even just running java -version). We think this issue is related to the JVM not having access to a system resource (file/dir) that we need to export to the compute nodes. However, the given error message is not terribly helpful.
1) Is there a tool to help us decode the given Error ID?
2) Is there a document that would tell us what the JVM is doing as it starts up? I don't mind RTFM'ing if I know where to get the FM... :-) The only documentation I've come across is about JVM options. I'd like to get information about system resources the JVM tries to access when starting...
3) What's up with the bug database? I found a report with this error ID but I get a page with 'Sorry. We couldn't find your document' !
Result of 'java -version' on compute node:
# HotSpot Virtual Machine Error, Internal Error

Here's what we get when run on the master node:
