Designed for scale
Compression and communication, designed together.
Our work advances each area independently and brings them together in end-to-end systems for AI and scientific workloads.
Efficient communication
Collective communication methods reduce data movement and support large distributed AI and scientific workloads.
Compression-communication co-design
Compressed-domain and homomorphic techniques connect both areas to eliminate avoidable work.
