The Peer Review Board assists the Scientific Council and the Board of Directors in the reviewing of research proposals applying for supercomputer resources; it evaluates the submitted project proposals and makes recommendations for appropriate grants of supercomputer resources to the applying scientists.

The NIC regularly - at present once a year - invites research proposals to be submitted. Project requests can in principle be filed by any scientist qualified in the respective field of research. Computer resources are primarily assigned on the basis of independent expert opinions following the criteria and procedures of Deutsche Forschungsgemeinschaft DFG (German Research Society). The user groups are mainly from Germany. However, NIC also strives to support researchers in Europe with computing time.

The Peer Review Board is composed of scientists in NIC's main research fields. The committee can call in external experts if required.
