The Dutch Research Council (NWO) provides access to SURF HPC services through their "Computing Time on National Computer Facilities".
Affiliates of one of the Dutch Universities or Grand Technology Institutes can submit an application for computing capacity. The scope of the call, and more information on who can apply, and how, can be found here: https://www.nwo.nl/onderzoeksprogrammas/rekentijd-nationale-computersystemen
These proposals will be peer-reviewed by and discussed within the NWO Committee for the Scientific Use of Supercomputers (WGS), which has been mandated by the NWO board to grant HPC resources. The number of referees depends on the actual amount of computing time you apply for. NWO may ask you for clarification of your request, based on comments of the referee(s). During the next scheduled WGS meeting, a granting decision will be taken. This procedure may take 4-8 weeks, since referees and a meeting of the WGS are involved. The NWO office (to be confirmed by the WGS) is in general able to provide you with a preliminary amount of computing time, which is around 10-20% of what you applied for.
If your proposal is accepted, you will receive a granting letter. SURF will receive a copy of the proposal and granting decision and subsequently will contact you with directions on how to obtain your account(s) on our systems.
