Tom's Hardware: Tachyum Submits Bid to Build 20 Exaflops Supercomputer.

"Tachyum on Tuesday said that it had submitted a bid to the Department of Energy to build a 20 exaflops supercomputer in 2025. The machine would be based on the company's next-generation Prodigy processors featuring a proprietary microarchitecture that can be used for different types of workloads.

"The U.S. DoE wants a 20 exaflops supercomputer with a 20MW–60MW power consumption to be delivered by 2025. The system is set to be installed at Oak Ridge National Laboratory (ORNL) and will complement the lab's Frontier system that went online earlier this year.

"Tachyum does not disclose which hardware it proposed to the DoE, but only says that it has its 128-core Prodigy processor today as well as a higher-performing Prodigy 2 processor in its roadmap, so it is safe to say that by 2025 it will have the latter on hand and it could be able to address the upcoming system.

"Tachyum's Prodigy is a universal homogeneous processor packing up to 128 proprietary 64-bit VLIW cores that feature two 1024-bit vector units per core and one 4096-bit matrix unit per core. Tachyum expected its flagship Prodigy T16128-AIX processor(opens in new tab) to offer up to 90 FP64 teraflops for HPC as well as up to 12 'AI petaflops' for AI inference and training (presumably when running INT8 or FP8 workloads). Prodigy consumes up to 950W and uses liquid cooling.

"That was all before Tachyum sued Cadence, its intellectual property provider, for lower-than-expected performance of its Prodigy processor. We have no idea what the current performance expectations are for the chip.

"In theory, Tachyum could power an exaflops system using over 11,000 of its Prodigy processors, though power consumption of such a machine would be gargantuan. Presumably, Prodigy 2 has a better chance to meet the needs of a next-generation exascale system than the original Prodigy.

"There is currently one exaflops-class supercomputer in the U.S., the 1.1 exaflops Frontier system at Oak Ridge National Laboratory (ORNL) that is based on AMD's 64-core EPYC CPUs as well as Instinct MI250X compute GPUs. There are two more exascale systems being built in the USA, the 2 exaflops Aurora machine powered by Intel's 4thGeneration Xeon Scalable processors and Xe-HPC compute GPUs (aka, Ponte Vecchio) as well as the ">2 exaflops" El Capitan supercomputer based on AMD's Zen 4 architecture EPYC CPUs and Instinct MI300 GPUs.

"One of the interesting things about the DoE's supercomputing plans is that from now on it wants to upgrade its high-performance compute capabilities every 12–24 months, not every 4–5 years. As a result, the DoE will be more eager to adopt exotic architectures like Tachyum's Prodigy than it is today.
