Despite high-performance, multi-GPU MR simulations are not widespread. In this study, we present coreMRI, an advanced simulation platform delivered as a web-service through an on-demand, scalable cloud-based and GPU-based infrastructure. coreMRI achieved with a 8xGPUs configuration a speedup of up to 63 when compared to a single-GPU configuration, bringing hour-long simulations down to a couple of minutes. In conclusion, coreMRI allows its users to exploit the highly-tuned computer performance of GPUs on MR simulations with neither upfront investment for purchasing advanced systems nor technical programming expertise.
