HPC at IU user,
The monthly maintenance was completed. IU’s high performance computing and storage systems are fully available to you.
Next Maintenance
Sunday, May 16, 2021, 7am – 7pm
Compute Resources
Review module changes for the past 60 days here.
- TORQUE and Moab job scheduling was retired April 12, 2021 and are no longer available on Carbonate. Job scheduling is now managed through Slurm.
- For more about SLURM, see Use Slurm to submit and manage jobs on high performance computing systems.
- There have been several changes to deeplearning, python, and tensorflow modules. The current status of each is:
- deeplearning/1.13.1 (retired)
- deeplearning/2.0.0 (retired)
- deeplearning/2.2.0 (retired)
- deeplearning/2.3.0 (default)
- python/2.7.13 (retired)
- python/3.6.1 (retired)
- python/3.6.8 (default)
- All tensorflow modules (retired)
- The CPU version of TensorFlow is now included in the Python modules.
- For the GPU version of TensorFlow use the Deep Learning modules.
- Based on user feedback, the maintenance update emails have been discontinued.
- No updates.
Storage Resources
- All data on /N/slate has been migrated to a faster set of newer hardware.
- Slate users now have a quota of 6.4 million files.
- Note: directories and symbolic links are also considered files in Linux.
- The new Slate system does not support native on disk compression. Some of your files may appear larger as they are now uncompressed and occupying more space.
- Slate-Project will also be migrating to a faster set of newer hardware. The sheer size of Slate-Project makes it prohibitive to attempt to finalize migration for every project during a single monthly maintenance period.
- The staggered migration will begin after May maintenance.
- Data will be migrated on a per project basis.
- All project owners and participants will receive a generic email with further details before the overall migration begins.
- A per project communication will follow to individual project owners and participants to inform them of their upcoming migration period.
- Project paths will remain the same. However, to allow continuous migration, symbolic links will be used to point projects to old Slate-Project until migration is complete for all projects.
- The new Slate-Project system, like Slate, does not support native on disk compression. Any quota gains you received from using compression will be gone.
- A new file system, Slate-Scratch, has passed performance metrics and has been mounted on IU’s HPC systems for further testing.
- Performance has exceeded 500,000 file creates and removes per second and has surpassed an aggregate transfer rate of 60 GB/s.
- Detailed information regarding the new Slate-Scratch service will be available via the IU Knowledge Base in the coming weeks. The goal is to make the service available by June.
