NVIDIA has a number of existing contributions to coronavirus research, including the 27,000 GPUs inside the Summit supercomputer and those inside many of the computers from the crowdsourced Folding@Home project. This is still a significant step forward, though, and might prove lifesaving if it leads to a vaccine or more effective containment.
Correction, 2:25PM ET: This story and its headline originally claimed that NVIDIA was donating 30 supercomputers to the COVID-19 High Performance Computing Consortium. NVIDIA is not directly providing computers (aside from its SaturnV supercomputer); instead it is using its background in AI and optimizing supercomputer throughput to the group. We apologize for the error.
