CSCS resources currently distribute compute time through the following allocation schemes.
CSCS CHRONOS annual call for proposals has been transferred into the PRACE Tier-0 Call for Proposals as of PRACE Call 14.
Production projects are aimed at the production work for a specific scientific project. Production projects can be submitted at any time. However there will be only two allocation periods on April 1st and on October 1st and therefore deadlines always apply. Projects are granted access based on scientific merit and technical feasibility. Allocations are valid for one year.
Development projects are meant for work on codes and algorithms. These projects can be submitted at any time. However for large development proposals there will be only the regular two allocation periods on April 1st and on October 1st. Small development projects are granted based on technical and feasibility assessment. Whereas large development projects are granted based on scientific merit and technical feasibility therefore deadlines always apply.
Preparatory projects are intended for users who are new to CSCS to allow them to port and test their codes before applying for a Production Project. Existing users who wish to port and test a new code or application may also apply for a Preparatory Project.
These projects are granted a limited and finite amount of compute resources.
Multi-year projects are expected to submit a renewal report to assure then continuation of the project.
