The resources allocated to the HEC-WSI are awarded as ‘ARCHER2 time only’, i.e. the following access modes only provide access to ARCHER2 resources and not funding for other items (such as staff time). ARCHER2 costs are notional rather than real costs.

The HEC-WSI currently offers three access modes (plus a dedicated allocation for early career researchers (ECRs) incl. training and support):

  • Porting and Benchmarking (PB);
  • Code Development (CD), and;
  • Project Access (PA).

Please see the table below for more details and links to the application forms for each access mode.
