Spring Maintenance Downtime: May 8-14, 2023

Stokes and Newton will be taken down per our bi-annual routine maintenance cycle during early May. Specifically, the clusters will be unavailable from Monday, May 8 through Sunday, May 14, 2023.
The primary objectives during this downtime is to integrate a new storage system, perform maintenance on the GPU cluster (Newton) with expanded capabilities, and perform other tasks we cannot do while the system is operational.
Recall that we routinely bring the system down twice a year, once in late Fall and once in late Spring. We will keep the users notified in advance of such downtimes, but we recommend you build such expectations into your workflow. Though we anticipate no data loss during this time, it's never a bad idea to backup your materials. So we suggest you use this opportunity to copy salient data and code off of Stokes and Newton prior to the downtime.
Changes due to Summer 2022 Maintenance

The ARCC has completed the Summer maintenance cycle and Stokes and Newton are back in operation. Please remember that the ARCC brings both clusters down for one week, twice per year: once after Spring semester (this downtime) and once after fall semester.
Summary of Changes:
- Slurm (job scheduler) upgraded to version 21.08.8-2
- NVIDIA GPU Drivers on Newton upgraded to version 510.47.03
- We have retired all 16-core Aspen nodes that were still in use. ec249 to ec296 have gone to a well-earned retirement after almost 12 years in use!
- Thanks to the Jump Start Fund of President Cartwright's 2021-2022 Strategic Investment Program, we have installed 36 brand-new 48-core nodes (each with 256GB of RAM and 100Gbps HDR Infiniband) to Stokes! Known as ec113 to ec148, they are ready to serve the general-purpose computational needs of UCF researchers for many years to come.
- Even after the retirement of the old nodes above, these new nodes increase the size of Stokes and now provide a total of 5,816 cores!
- We also will still be adding 18 more nodes in the future once they ship and arrive.
ARCC to Hire Undergraduate Students

The Advanced Research Computing Center (ARCC) in research park is looking to hire undergraduate students to help with our high performance computing (HPC) resources. The student will help resolve problems for users, investigate issues related to the management and performance of our clusters, build & optimize software packages for the clusters, work to improve our documentation, and get hands-on experience with HPC specific hardware and software. Candidates should have experience with the GNU/Linux operating system, including scripting and standard methods for building software in UNIX-like environments. Special consideration will be given to students with experience running parallel and distributed programs, as well experience with scientific visualization tools.
For more information about the position, please contact Glenn Martin ( m...@ist.ucf.edu (Click on "..." to reveal the address)). For more information about the ARCC and its resources, please see our home page.
Thank You,

Changes due to Fall 2021 Maintenance

Stokes and Newton have returned to operation! Please remember that we have two such scheduled maintenance downtimes per year, one after Fall term (the one we just completed) and one after Spring term.
Please take a moment to read over the changes:
- We upgraded the Infiniband network infrastructure to HDR (most nodes now run at 100 gigabits per second — up from 56 gigabits per second!). All new switches and all new cabling were installed within the past week!
- Due to hardware requirements and impending additions, we have retired some of our oldest nodes. ec297 to ec324 have gone to a well-earned retirement after serving ARCC users for 11 years!
We appreciate your patience and wish you the best with your research!
