PRACE Preparatory Access Call

Sigma2 invites all interested scientists, whose projects fit the criteria of the PRACE Preparatory Access Call, to submit their projects.

Preparatory access is intended for testing and developing codes in order to prepare applications for PRACE Tier-0 project access. In particular, we would like to draw your attention to the Preparatory Access Type C and Type D, which includes code development with support from PRACE experts. This is similar to the Sigma2 Advanced User Support (AUS) mechanism for extended user support.

Type C provides direct access to a Tier-0 system. Type D offers users to start the optimisation work on a PRACE Tier-1 national  system to finally reach PRACE Tier-0 system scalability.

Rolling call

The Preparatory Access Call is a rolling call, researchers can apply for access all year. There are no closing dates, proposals for Type C and Type D will be reviewed every third month. 

Further information are given on the PRACE web page

The criteria for the PRACE Calls as well as complete information on the PRACE machines, how to apply and on the PRACE peer review process can be found on the website mentioned above.

Please contact us at Sigma2 if you need assistance in exploring this opportunity.


PRACE (Partnership for Advanced Computing in Europe) is a Research Infrastructure that allows researchers from across Europe to apply for time on high-performance computers from a
series of hosting nations via a central peer review process.

These computers are typically very capable (able to handle a large number of parallel threads) than what is currently available through Sigma2, and have requirements for the scaling and parallelism for the codes to run.
