The HPC cluster will be down for maintenance on Tuesday, Oct 15, 2024 beginning at 6 am. You may continue to submit jobs until the maintenance period begins, but if the system determines your job will not have time to finish, it will not start until the cluster is returned to service.
All systems are expected to return to service by Wednesday, Oct 16 at 6 am.
IMPORTANT MAINTENANCE NOTES Expansion of /home To transition away from the Qumulo filesystem, we will migrate all /home directories to the GPFS filesystem and automatically increase each user’s /home directory limit to 200GB.

Due to the new [licensing restrictions by Anaconda](https://legal.anaconda.com/policies/en?name=terms-of-service#terms-of-service) on research usage, the licensed Anaconda distribution will be removed from the system on October 15, 2024. The current anaconda/2023.07-py3.11 module will redirect to the miniforge/24.3.0-py3.11 module, switching to conda-forge as the default package installation channel with fewer preinstalled packages. Existing environments will not be affected. However, using Anaconda default channels for research without a personal license will violate the Anaconda license. For instructional use, package installation from licensed channels is still allowed Maintenance: Oct 15, 2024 The UVA high-performance computing (HPC) system will be down for maintenance on **Tuesday, Oct 15, 2024,** beginning at 6 a.

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.

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.

Rivanna will be down for maintenance on Tuesday, May 28, 2024 beginning at 6 a.m. You may continue to submit jobs until the maintenance period begins, but if the system determines your job will not have time to finish, it will not start until Rivanna is returned to service. While drive mapping and project storage will be unavailable, other storage will remain accessible through Globus.
All systems are expected to return to service by Thursday, May 30 at 6 a.m.
IMPORTANT MAINTENANCE NOTES Hardware and partition changes afton: We are pleased to announce the addition of 300 nodes, 96 cores each, based on the AMD EPYC 9454 architecture.

During the July 18th maintenance, RC engineers installed a new /scratch file storage system on Rivanna. We have created sample scripts and instructions to help you transfer your files from the previous file system to the new one.(Expand the link below for details.) The previous scratch filesystem, now called /oldscratch, will be permanently retired on October 17, 2023 and all the data it contains will be deleted.
Users should clean up their /oldscratch directory in preparation, to minimize the load. A sample script is posted below.
Modified queue limits have been implemented to provide maximum read/write performance of the new /scratch filesystem.
