The DRMAA API
Setting up the DRMAA API.
Motivation
The Distributed Resource Management Application API (DRMAA) → is used by workflow managers such as cgatcore → to communicate with HPC queue managers while submitting and monitoring jobs.
The drmaa package provides a Python interface to the DRMAA library.
This page describes the setup necessary for using DRMAA on the CCB cluster. This setup is a prerequisite for using cgatcore → pipelines.
Setup
On the CCB cluster, in your ~/.bashrc file, add the following chunk of code
to set the environment variable DRMAA_LIBRARY_PATH.
If your '.bashrc' file already contains the conditional statement 'if [[ $PS1 ]]', you can add only the 'export' statement within the existing bloc of code.
if [[ $PS1 ]]; then
export DRMAA_LIBRARY_PATH=/usr/lib64/libdrmaa.so
fi
You are now ready to use the DRMAA library in cgatcore → pipelines.
