HPC is a lot of computer processing power linked together, thinking through and solving different pieces of big problems in parallel. HPC makes it possible to answer big questions in a fraction of the time it would take when using individual desktop PCs. With HPC resources, some problems can be solved that could never be solved before.
With this problem-solving capability, scientists start to ask questions they would never have thought to ask. And universities are increasingly the hubs of the HPC systems that ask these questions, solve these problems, and change the world.
High-performance computing does, however, come at a high cost.
