Allocations

Rockfish supports several types of allocations:

Faculty members at Johns Hopkins University can request allocations using the Rockfish portal found here. This portal is a great tool for PIs to manage their allocations, users and accounts. For information on requesting an allocation, watch this video.

Allocations will be reset on a quarterly basis. The model is “use it or lose it”. Any unused part of an allocation will not roll over to the next quarter.

NOTE:  All projects must submit periodic reports via the Rockfish portal or to XSEDE.

MRI-Related Allocations
  • PIs who participated in the proposal to NSF should submit a short proposal justifying the request for cpu-cycles and storage.
  • Regular cpu-cycles. This allocation will allow the use of the regular/standard compute nodes. The limit  is 750,000 core-hours per quarter.
  • Large memory cpu-cycles.  This allocation will allow the use of large memory nodes. Applications and simulations must use more than 192GB of memory. Limit 50,000 core-hours per quarter.
  • GPU allocation.  This allocation will allow the use of GPU nodes. All scientific applications should make use of the GPUs.  Limit 50,000   core-hours.
  • Storage (GPFS) allocations.  This allocation will assign storage to the group on an annual basis.
Condo-related allocations:
  • Deans’ Condo allocations
    • The Dean’s office will offer small/startup faculty members allocations. These allocations WILL follow the MRI-topics and will be part of the annual report to the funding agency.
  • Morgan State University allocations
    • A subset of allocations will follow a model developed at Morgan State University as a partner for this grant.
  • XSEDE allocations
    • Follows the process established for XSEDE allocations (XRAC) 
  • PIs who contribute condos will have an allocation (or additional allocation) equivalent to the size of the condo.
    • For example a one node condo is equivalent to 100,000 core-hours per quarter.
  • Condo storage and purchased storage. This allocation is composed of the storage given by default plus the size of the storage purchased. It may cover different file sets.
  • New faculty members will have allocations equivalent to the size of the condo in their LOI, or as offered by the Dean’s office.
