very Large memory java jobs
We have several bio-computing experiments that need over
2GB of heap. We are running on linux-2.4.19 on machines
with 4GB of memory.
$ java -version
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build
Java HotSpot(TM) Client VM (build Blackdown-1.3.1-FCS, mixed mode)
Allocating 1.9GB appears to work (will crash sometime though).
$ java -Xmx1900m J
Allocating 2GB and above always fails.
$java -Xmx2000m J
Error occurred during initialization of VM
Could not reserve enough space for object heap
Can anybody suggest a solution or work around.
