Hi Lahiru, Below are my two cents on this -
*Scratch working directory*: Directory you submit your computational jobs from, interactive or otherwise. For performance overhead and other issues, you're not supposed/allowed to submit jobs from head node's native file system (e.g. ext4) in clustered environment. So, you transfer your job scripts and input data to the scratch space (running on a different file system for back and forth data transaction/communication between computational nodes and a the distributed file system, e.g. lustre) before submitting jobs. *Static working directory*: As the name suggests, it should be static and solely under control of user. This is the directory where the output/error files are stored (parameters you specify in your PBS script). So, in most cases, you can specify the values for scratch working directory and static working directory as the same (e.g. /lustre/scratch/<user name>/<working-directory>). Hope this helps!
