While OSC has upgraded the Pitzer cluster to RHEL 9, you may encounter difficulties when migrating jobs from RHEL 7 to the new system. To help you continue your research, we provide a containerized RHEL 7 environment on Pitzer RHEL 9. This container replicates the original RHEL 7 system and software environment used on Pitzer.
Note: This containerized RHEL7 environment is a temporary solution and may be terminated at any time without prior notice.
The Pitzer cluster (on RHEL 9) 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.
The Pitzer RHEL 9 cluster (hereafter referred to as "Pitzer") is now running on Red Hat Enterprise Linux (RHEL) 9, introducing several software-related changes compared to the RHEL 7 environment used on the Pitzer. These updates provide access to modern tools and libraries but may also require adjustments to your workflows. Key software changes and available software are outlined in the following sections.
Intel's implementation of the Message Passing Interface (MPI) library. See Intel Compilers for available compiler versions at OSC.
