The monthly maintenance was completed. IU’s high performance computing and storage systems are fully available to you.
Sunday, September 13, 2020 | 7am – 7pm
- The Karst supercomputer at IU will be retired from service in December 2020. Here is what you need to know about the retirement:
- You will not be able to login to Karst after Friday, December 18.
- Data in the home directories of Karst will remain accessible from the other IU supercomputers, Big Red 3, Carbonate, and the Karst replacement, through December 31, 2021.
- The replacement system, which will be available to all IU students, staff, and faculty, consists of 92 compute nodes and has significantly more compute power than Karst. Each node has two 64-core CPUs and 512GB of RAM. More details on system configuration and availability will be provided in the coming months.
- A new general purpose GPU partition is now available on Carbonate.
- This GPU partition consists of an additional 24 GPU-accelerated nodes. Each node is equipped with two Intel 6248 2.5GHz 20-core CPUs, 768GB of RAM, 4 NVIDIA V100-PCIE-32GB GPUs, and one 1.92TB solid-state drive.
- More information is available here: https://kb.iu.edu/d/avjk.
- The ThinLinc server has been updated to 4.12.
Big Red 3:
- The Big Red 3 Supercomputer Operating System was updated from CLE6.0up07 (SLES 12sp3) to CLE7.0up02 (SLES15sp1). All software and software modules were reinstalled as a result of the OS upgrade. All user-owned applications will need to be recompiled. As a result of the software changes, any jobs that were pending and had not run at the start of maintenance were canceled. Those jobs will need to be resubmitted with the updated software stack.
Data Capacitor II (DC2):
- DC2 will be retired December 11, 2020.
- DC2 will go read-only October 11, 2020.
- If you have a project on DC2, you will need to relocate that project to Slate or Slate-Project.
- If your workflow relies on DC2 scratch, you will need to alter your workflow to use Slate or Slate-Project.
- Contact email@example.com if you need help migrating your workflows.
Slate and Slate-Project:
- Slate is available for the persistent storage of user data and is primarily for individual use. See Slate’s terms of service.
- Slate-Project is available for the persistent storage of collaborative or project data. See Slate-Project’s terms of service.
Geode (Home Directories):
- No updates.
Scholarly Data Archive (SDA):
- No updates.
