HPC Accounts

For access to computational resources.

Each account receives a home directory with a 10GB allocation, but this space is intended for storing source code and applications and not for research data. Faculty members and PIs automatically get an additional 256GB of research data storage. Additional storage can be purchased.

Exploratory

  • Limited to using 16 CPU for 48 hours or any combination not to exceed these limits (e.g. one job using 16 CPUs for 48 hours, or 2-jobs using 8 CPUs for 24 hours, or 1-job using one CPU for 32 days, etc.)
  • Limited to using 16 CPUs at a time
  • Low priority in the job queue
  • Free for Brown University faculty, researchers and students

Premium

  • Full access (subject to a per-user limit) to HPC resources for an individual user (cannot be shared by multiple people)
  • Medium priority in the job queue
  • Good option for an individual researcher or for a research group where only one user needs the bulk of the HPC resources (other members can setup exploratory accounts)

Group Premium

  • Includes six premium accounts, and additional users can be added at a discount
  • Good option for research groups or labs where all members need full access to HPC resources

Condo Membership

PIs may choose to contribute funding for the purchase of additional hardware, to add capacity or capabilities to the core system. The hardware purchase can be tailored to specific research needs (e.g., GPU's, SMP nodes, large memory, solid-state drives, etc.), but all equipment must meet a basic level of compatibility with the existing cluster. The exact hardware configuration will be determined by consensus of the PI and CCV management.

  • Any number of Exploratory, Premium, or Group Premium accounts can be affiliated with the condo.
  • These accounts receive, collectively, the highest priority (next to run priority) in the job queue for a portion of the system equivalent to the condo (not necessarily the same physical nodes) for a period of 3 years without incurring additional account access fees. In addition, condo users will have an allocation 1.25X the size of the purchased condo. Condo users receive next to run priority on their resources.
  • During the first 3 years, high priority access will be implemented by queuing and scheduling policies that promote affiliated jobs to the top of the queue for execution scheduling.
  • In the event that the condo is not immediately available for scheduling, the condo user will have next-to-run priority for the condo.
  • In years 4 and 5, the priorities will be successively decreased to those of the normal priority accounts.
  • In the case that a condo user's jobs request more resources than contained in the condo, they will be scheduled with a preferred priority calculated with terms proportional to the size of the condo (relative to the entire system) and inversely proportional to the size of the request. This will always yield a priority higher than the base priority.

RI-EPSCoR users

The RI-EPSCoR web site provides information on how to request approval for an RI-EPSCoR sponsored account and use of CCV resources.
