High Bandwidth Memory
Overview of the High Bandwidth Memory on Cardinal's Dense compute nodes
Cardinal Programming Environment
Compilers
The Cardinal cluster supports C, C++, and Fortran programming languages. The available compiler suites include Intel, oneAPI, and GCC. By default, the Intel development toolchain is loaded. The table below lists the compiler commands and recommended options for compiling serial programs. For more details and best practices, please refer to our compilation guide.
PyTorch 2.4.0 available
A PyTorch 2.4.0 conda environment is now available. Usage via: module load pytorch/2.4.0 See OSC PyTorch software page for more details.
Desmond 2023-4 is available on Cardinal and Owens
Desmond 2023-4 has been installed on Cardinal and Owens. Note that the vendor has changed their version syntax from a dot to a dash, but we have kept the dot syntax for our modules. These are GPU enabled installations. Usage is via the module desmond/2023.4.
Cardinal SSH key fingerprints
These are the public key fingerprints for Cardinal:
cardinal: ssh_host_rsa_key.pub = 73:f2:07:6c:76:b4:68:49:86:ed:ef:a3:55:90:58:1b
cardinal: ssh_host_ed25519_key.pub = 93:76:68:f0:be:f1:4a:89:30:e2:86:27:1e:64:9c:09
cardinal: ssh_host_ecdsa_key.pub = e0:83:14:8f:d4:c3:c5:6c:c6:b6:0a:f7:df:bc:e9:2e
Batch Limit Rules
The PBS compatibility layer is disabled on Cardinal so PBS batch scripts WON'T work on Cardinal, though it works on the Pitzer cluster. You also need to use
sbatch (instead of qsub) command to submit jobs. Refer to the Slurm migration page to understand how to use Slurm. Memory limit
MVAPICH
The default MPI module, MVAPICH, will be updated from version 3.0 to 4.1 on May 12, 2026, during the upcoming scheduled downtime. For more information, please visit:

MVAPICH is a standard library for performing parallel processing using a distributed-memory model.
System Downtime August 6 2024
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 6 2024. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. There will be a short outage of the state-wide licenses; MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., August 6. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.
AutoDock
AutoDock is a a suite of automated docking tools. It is designed to predict how small molecules, such as substrates or drug candidates, bind to a receptor of known 3D structure. AutoDock has applications in X-ray crystallography, structure-based drug design, lead optimization, etc.
