Starting May 2024, the charge model for Picotte compute and storage usage is defined as follows:

• Picotte will have two tiers of usage, a free tier and a priority (paid) tier. 
• The free tier includes the following partitions:
  
  • def-sm
    
    • a free tier partition for CPU nodes. 
    • Jobs on def-sm are limited to a maximum of 4 nodes, 24-core per node, and 12 hours of wall time. 
  • gpu-sm
    
    • A free tier partition for GPU nodes.
    • Jobs on gpu-sm are limited to a maximum of 1 node, 12-core per node, 1 GPU card, and 4 hours of wall time. 
  • All approved users will have access to both free-tier partitions
  • Jobs running on free tiers are preemptable by jobs running on priority (paid) tier 
• The priority tier will have the rate of $0.01 per SU, with 1 SU (service unit) defined as a single core-hour. 
  
  • The scaling factors for various partitions are defined as follows:
    
    • def/long: 1 SU per core-hour
    • bm: 68 SU per RAM TiB-hour
    • gpu/gpulong: 43 per GPU device-hour
  • Storage:
    
    • Each research group (Slurm account) is now allowed 0.5TB without charges
    • Above this limit, the charge rate is $10 per TB month
