PRACE is currently in a transition phase to a new funding and governance model. Unfortunately, this necessitates a temporary reduction in the number of Tier-0 resources currently available.

The computer systems and their operations accessible through PRACE are provided for this 26th cut-off by 4 PRACE members:

  • GCS representing Germany – Hazel Hen (GCS@HLRS), Juqueen (GCS@FZJ), and SuperMUC (GCS@LRZ)

The process to access resources after the communication of the decision on allocation is two-fold:

  • Awardees are asked to confirm their availability and readiness to use the awarded resources during the stated period of time
  • Access is provided after receipt of a positive reply

The allocation decision, including the type of access, start/end dates, duration and the resources awarded is not open for negotiation.

As detailed in the Term of Access of the Call for Proposals, “the award of Preparatory Access proposals of types A, B and C is limited by the amount of resources available. For type C, there are also limitations regarding the availability of the support from experts (in terms of staff hours) and the type of expertise required.”

In case of oversubscription of a particular resource, resources will be awarded on a first-come, first-served basis to suitable proposals based on the submission date until the resources are exhausted.
