Theta/ThetaGPU

Theta supercomputer

More than 5 billion computing hours are allocated on ALCF systems each year.

Our Theta/ThetaGPU supercomputer performs complex and diverse workloads, integrating data analytics with AI training and learning into a single platform.

Theta

Theta is an 11.69-petaflops supercomputer based on Intel processors and interconnect technology, an advanced memory architecture, and a Lustre-based parallel file system, all integrated by Cray’s HPC software stack.

ThetaGPU (available soon)

ThetaGPU is an NVIDIA DGX A100-based system. The DGX A100 comprises eight NVIDIA A100 GPUs that provide a total of 320 gigabytes of memory for training AI datasets, as well as high-speed NVIDIA Mellanox ConnectX-6 network interfaces.
