Singularity is a container runtime designed for use in HPC.
Containers can run without root access on any Linux system with Singularity installed.
Containers are immutable and directories are mounted to read or write from files. Some directories are mounted automatically when an image is run. More information is available here.
Installing the Singularity runtime requires root access to a Linux machine.
Your HPC system may already have it installed.
If not, your HPC staff can get it from a EPEL (CentOS/RHEL) or a Debian/Ubuntu repository. More information is available here.
First, download the RevBayes Singularity image. RevBayes_Singularity_1.1.1.simg.
singularity run --app rb RevBayes_Singularity_1.1.1.simg
singularity run --app rb RevBayes_Singularity_1.1.1.simg myscript.rev
Any arguments after RevBayes_Singularity_1.1.1.simg are passed to the rb command.
The container also contains the MPI version of RevBayes. This version was built with the ubuntu-provided OpenMPI implementation (3.1.3) and may not work with other MPI versions.
To run a script file:
mpirun singularity run --app rbmpi RevBayes_Singularity_1.1.1.simg myscript.rev
If it does not work with the version of MPI you have on your cluster, you could ask your administrator to rebuild the image for the appropriate MPI version for your environment (see recipe below). More information is available here.
