The service charges listed below apply only to researchers from labs whose PIs do not have a primary or secondary faculty appointment in an HMS Basic Science department (external users).

Please reference this HMS policy for more details.


Charges will be based on total number of compute hours in a given billing period.

Core Charge Rate (1 core x 1 hour) 
RAM Charge Rate (1 GiB x 1 hour) 
Standard Compute  Compute job with less than 256GiB RAM reserved  $0.0105   $0.0013  
High Memory Compute  Compute job with more than 256GiB RAM reserved  $0.0144  $0.0006  


Core Charge Rate ( 1 card x 1 hour)
GPU Compute  Single or double precision  $0.3428    


Storage usage charge is based on the sum of daily usage divided by the number of days in a quarter. It does NOT depend on the folder size limit.    
Charge Rate (1 TiB*, per year) 
Charge Rate (1 TiB*, per quarter) 
Active Compute  Fast SSD for HPC Compute (O2)  $224.06   $56.02
Active Collaborations  Fast disk for lab computers (research.files)  $169.65   $42.42
Standby Slower disks for less frequently accessed data  $111.64   $27.91
