Slurm Migration
Overview
Slurm, which stands for Simple Linux Utility for Resource Management, is a widely used open-source HPC resource management and scheduling system that originated at Lawrence Livermore National Laboratory.
It is decided that OSC will be implementing Slurm for job scheduling and resource management, to replace the Torque resource manager and Moab scheduling system that it currently uses, over the course of 2020.
Backup failures for Project on August 1st and 2nd
OSC experienced backup failures on our GPFS file systems (both Project file systems, /fs/project and /fs/ess) the mornings of August 1st and 2nd. The underlying cause was identified and backups were operating as expected the morning of August 3rd. As a result of these failed backups, OSC will not be able to complete some file restore requests for files changed between approximately 2020-07-31 02:30 through 2020-08-02 02:30.
System Downtime August 18, 2020
A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 18, 2020. The downtime will affect the Pitzer, Ruby and Owens Clusters, web portals and HPC file servers. Login services, except for my.osc.edu, will not be available during this time. OSC clients are able to log into my.osc.edu during the downtime but no changes will take place until the downtime is completed. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., August 18, 2020.
PETSc
PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It supports MPI, and GPUs through CUDA or OpenCL, as well as hybrid MPI-GPU parallelism.
GAMESS 30Sep2019R2 is available on Owens and Pitzer
GAMESS version 30Sep2019R2 has been installed on Owens and Pitzer. Usage is via the module gamess/30Sep2019R2. For installation details use command: "module help gamess/30Sep2019R2". For help loading an installation, use command: "module spider gamess/30Sep2019R2".
intel mpi Default Version Update to 2019.7
The previous intel mpi default version is 2019.3, however this version had an issue with MPI-IO in home directories, so we updated the default version to 2019.7 on June 15, 2020.
Applications built with intel mpi version 2019.3 should work with version 2019.7 without rebuilding.
We also removed intel mpi version 2019.5 that had another MPI-IO related issue on June 15.
