What is the reason for this maintenance?
Oscar's current operating system, RHEL-7, and its maintenance support phase will come to an end in June 2024. So Oscar is being upgraded to latest RedHat Enterprise Linux RHEL-9.2
We are also introducing a bunch of new features:
Upgraded OS - The OS has been upgraded with a newer kernel and improved security patches
Power Saving Mode: In the batch partition, idle nodes now enter a power-saving mode, consuming only about 40W. They seamlessly transition to high-performance mode just before job execution begins
GPU Direct Storage: GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU
SLURM Upgrade: We have tuned the scheduler to provide much higher throughput. Now supports json and yaml formatting for all slurm commands
SPACK & LMOD - Newer industry standard for installing and managing applications on Oscar. We now support multple shells bash,zsh & fish etc
