Please join us for a lively panel discussion of the high-performance computing infrastructure and support resources available to researchers in the Commonwealth of Virginia. Panelists from Virginia’s top research universities will provide an overview of the user base at their home institutions and discuss strategies for helping researchers make better use of existing HPC resources. Attendees are encouraged to share their own experiences and engage with panelists during this interactive Q&A session.
*Topic: High-performance Computing Resources in the Commonwealth of Virginia
When: April 27, 2022 01:00 PM, Eastern Time (US and Canada)

Rivanna and the Globus data transfer nodes (DTNs) will be down for maintenance on Tuesday, December 14, 2021 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.
Users will be unable to transfer data using Globus during the maintenance period. Rivanna and the Globus DTNs are expected to return to service by 6 a.m. on Wednesday, December 15.
IMPORTANT MAINTENANCE NOTES New GPU We are pleased to announce the addition of DGX A100 GPU to the gpu partition.

The Globus data transfer nodes (DTNs) and Rivanna’s parallel nodes will be down for maintenance on Tuesday, October 12, 2021, between 8 a.m. and 4 p.m. Users will be unable to transfer data using Globus or run parallel jobs on Rivanna during this period.
All other systems and services—including storage—are expected to continue operating normally.
IMPORTANT MAINTENANCE NOTES The following Rivanna software changes will be implemented during the maintenance period:
IDL/8.4- replaced by 8.8 (8.7.2 still available) ANSYS default version changing from 2021r1 to 2021r2

We are pleased to announce that AlphaFold is now available on Rivanna! Here are some of our user’s first few protein structure prediction calculations on Rivanna.
Simple ZFc protein: Similar results for AlphaFold (brown) and I-TASSER (blue). (This figure was created with the RCSB Pairwise Structure Alignment tool.)
146PduD-linker-ZFc protein: AlphaFold’s (left) superior ability to predict secondary structure, a β-sheet in its green-yellow region, whereas I-TASSER (right) is not sufficiently refined to feature any β-strands. (This figure was created with NGL Viewer.)

FAQ What is AlphaFold?
AlphaFold is an AI for protein structure prediction developed by Google DeepMind.

ITS has completed phase 1 of its network reconfiguration and ITS NAS storage volumes have been remounted on Rivanna. RC managed Research Standard and Research Project storage are also fully available. ITS home1 directories, including /nv/t* mounts, remain unavailable on Rivanna. Users will still be able to mount ITS home1 storage to their local workstations and transfer their data via Globus and the UVA Main DTN. We regret the inconvenience.

Rivanna will be down for maintenance on Tuesday, June 15, 2021, 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.
Rivanna is expected to return to service by 6 a.m. on Wednesday, June 16.
IMPORTANT MAINTENANCE NOTES Globus Some Globus users may need to rebuild their shared connections after the maintenance period has ended. Users who require assistance with this task are invited to join us for office hours between 10 a.

Phase 1 of the maintenance period is now complete. Rivanna’s standard, GPU, largemem, and front-end nodes have been returned to service. Pending jobs that were submitted before the maintenance began need to be resubmitted.
Rivanna’s parallel nodes will be released in phase 2 which we anticipate being finished by 5 p.m. on Tuesday, December 22.

In order to expedite users' access to the system, Rivanna will be returned to service in 2 separate phases:
During phase 1, which is expected to be completed in fewer than 72 hours from now, the standard, GPU, largemem, and front-end nodes will be reactivated. Rivanna’s parallel nodes will be released in phase 2 which should be finished within the 72 hour timeframe.

The maintenance period has been extended for another 72 hours minimum. We apologize for the inconvenience. Rivanna was expected to return to service on December 17, but ongoing electrical work in the data center and other obstacles have delayed our engineering team’s progress.
We will send out an e-mail announcement as soon as the maintenance period ends. Updates will also be posted on our website.

Research Computing will be activating a new accounting management package for Rivanna on June 17, 2020. The software was purchased from Adaptive Computing, which specializes in advanced management applications for high-performance systems. Rivanna users can expect to see more accurate reporting on their Service Unit (SU) balances and burn rates. Information on usage by individual members of an allocation group will also be available.
Commands such as allocations will remain but will reflect the new accounting. Users should be aware that the new accounting system implements “liens” on running jobs, and that the SUs requested for each job will be held in a reserved pool until the job completes.
