Coral-2 Exascale Machines will require Boatload of Accelerators

In this podcast, the Radio Free HPC team takes a look at daunting performance targets for the DOE's CORAL-2 RFP for Exascale Computers.

"So, 1.5 million TeraFlops divided by 7.8 is how many individual accelerators you need, and that's 192,307, which by the way looks like a prime number. Now, multiply that by 300 watts per accelerator, and it is clear we are going to need something all-new to get where we want to go."

The Request for Proposals is designed to get bids from vendors to build two and (potentially) three new exascale supercomputers. Each system is expected to cost between $400 – $600 million.
