HPC Maintenance: Aug 13, 2024
The HPC cluster will be partially down for maintenance on Tuesday, Aug 13, 2024 beginning at 6 a.m. The following nodes will be unavailable during this period:
all of parallel afton nodes in standard and interactive A40 GPU nodes in gpu The nodes are expected to return to service by Wednesday, Aug 14 at 6 a.m.
There is no impact on other nodes or services. Jobs on other nodes will continue to run.
Reinstatement of file purging of personal /scratch files on Afton and Rivanna
On Sep 1, 2024 RC system engineers will reinstate a file purging policy for personal /scratch folders on the Afton and Rivanna high-performance computing (HPC) systems. From Sep 1 forward, scratch files that have not been accessed for over 90 days will be permanently deleted on a daily rolling basis. This is not a new policy; it is a reactivation of an established policy that follows general HPC best practices.
The /scratch filesystem is intended as a temporary work directory. It is not backed up and old files must be removed periodically to maintain a stable HPC environment.
Key Points: Purging of personal scratch files will start on Sep 1, 2024.
Production Release of the Afton HPC System: July 2, 2024
Our new supercomputer, “Afton,” is now available for general use. This represents the first major expansion of RC’s computing resources since Rivanna’s last hardware refresh in 2019. Afton represents a substantial increase in the High-Performance Computing (HPC) capabilities available at UVA, more than doubling the available compute capacity. Each of the 300 compute nodes in the new system has 96 compute cores, an increase from a maximum of 48 cores per node in Rivanna. The increase in core count is augmented by a significant increase in memory per node. Each Afton node boasts a minimum of 750GB of memory, with some supporting up to 1.
