About the ALCF AI-Testbed

Argonne AI-Testbed at Argonne Leadership Computing Facility (ALCF) provides an infrastructure of next-generation AI-accelerator machines. It aims to help evaluate usability and performance of machine learning based high-performance computing applications running on these accelerators. The goal is to better understand how to integrate with existing and upcoming supercomputers at the facility to accelerate science insights.


  • Maintain a range of hardware and software environments for AI-accelerators
  • Provide a platform to benchmark applications, programming models and ML frameworks
  • Support science application teams to port and evaluate their applications
  • Co-ordinate with vendors with product developments
Currently, the AI-Testbed consists of Cerebras, SambaNova and GraphCore systems. We are working closely with other vendors to obtain more testbed systems.

Currently, the AI-Testbed has Cerebras, SambaNova and GraphCore systems set up and running. We are working closely with vendors including Groq, among others.

Cerebras (CS-1)

CS-1 is a wafer-scale, deep learning accelerator. Processing, memory, and communication in CS-1 reside in the Cerebras Wafer-Scale Engine (WSE).


Colossus GC2 Intelligent Processing Unit (IPU) was designed to provide state-of-the-art performance for training and inference workloads.


SambaNova systems aims to develop and accelerate AI applications at scale with a Reconfigurable Dataflow ArchitectureTM (RDA).

Groq (Available in 2021)

Groq tensor streaming processor (TSP) provides a processing core and memory building block to achieve 250 TFlops in FP16 and 1 PetaOp/s in INT8 performance.
