SciNet is the supercomputer centre at the University of Toronto, hosting Niagara, the fastest supercomputer in Canada, plus a range of other systems. SciNet provides Canadian researchers with computational resources and expertise necessary to perform their research on scales not previously possible in Canada. We help power work from the biomedical sciences and aerospace engineering to astrophysics and climate science. Our free education and training program for students and users helps them obtain advanced computing skills and knowledge needed in their research and in the workplace. SciNet — which provides resources for Compute/Calcul Canada, a national infrastructure for supercomputing-powered research, and SOSCIP, a Southern Ontario infrastructure for driving innovation — is funded by the Canada Foundation for Innovation, NSERC, the Government of Ontario, Fed Dev Ontario, and the University of Toronto.
