Interactive Usage

After connecting to ShARC (see Establishing a SSH connection), start an interactive session with the qrsh or qrshx command.

Java can be activated using one of the following module files

module load apps/java/17.0.4/binary
module load apps/java/13.0.2/binary
module load apps/java/11.0.2/binary
module load apps/java/jdk1.8.0_102/binary

Check that you have the version you expect. First, the runtime

$ java -version

openjdk version "17.0.4" 2022-07-19
OpenJDK Runtime Environment Temurin-17.0.4+8 (build 17.0.4+8)
OpenJDK 64-Bit Server VM Temurin-17.0.4+8 (build 17.0.4+8, mixed mode, sharing)

Now, the compiler

$ javac -version

javac 17.0.4
