Description: Suite of programs that allow users to carry out molecular dynamics simulations
SHARCNET Package information: see JDK software page in web portal
Full list of SHARCNET supported software



PATH INITIALIZATION

The binaries for this package are not included in your default path. Therefore its necessary to add the path manually using one of the following commands depending on your shell:

Bash Shell Users: export PATH=/opt/sharcnet/jdk/current/bin:$PATH

Csh Users: set path = (/opt/sharcnet/jdk/current/bin $path)


PROVIDED BINARIES

[roberpj@bul125:/opt/sharcnet/jdk/current/bin] ls jav*
java  javac  javadoc  javah  javap  javaws


MEMORY ALLOCATION ON ORCA LOGIN NODE

Java 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:

[roberpj@orc-login1:~] 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)
