Distributed Research using Advanced Computing (DiRAC) is an integrated supercomputing facility used for research in particle physics, astronomy and cosmology in the United Kingdom. DiRAC makes use of multi-core processors and provides a variety of computer architectures for use by the research community.

DiRAC and DiRAC II
Initially DiRAC was funded with an investment of £12 million from the Government of the United Kingdom's Large Facilities Capital Fund combined with funds from the Science and Technology Facilities Council (STFC) and a consortium of universities in the UK. In 2012, the DiRAC facility was upgraded with a further £15 million of UK government capital to create DiRAC II which has five installations:
- University of Cambridge HPC Service with 10000 cores and 1 Petabyte clustered file system
- Cambridge Cosmos shared memory Service with 1856 cores, 14 Terabytes of globally shared memory with Intel Xeon Phi coprocessors
- University of Leicester IT Services with 4352 cores and nonblocking minimal spanning switches
- The Institute for Computational Cosmology (ICC) at Durham University Service with 6500 cores
- University of Edinburgh 6144 node IBM Blue Gene/Q with 65000 cores and torus interconnects at EPCC
