MEMORY ALLOCATION ON ORCA LOGIN NODE

Java and javac will crash immediately when run interactively on orcas login nodes unless a command line argument with format XmxNNNN (where NNNN specifies the requested memory allocation pool) is specified. The value should be chosen less then the 1GB hard memory limit of the login node. For instance 512mb would be acceptable as shown here:

[roberpj@orc-login1:~] /opt/sharcnet/jdk/current/bin/java -Xmx512m -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed mode)

[roberpj@orc-login1:~] /opt/sharcnet/jdk/current/bin/javac -J-Xmx512m -version
javac 1.6.0_13
