Cerebras ' wafer-scale chip bypasses many of the computational speed lossesthat come from many GPUs talking to each other, as well as loading data to and from memory.
The company demonstrated that its second generation.
engine, WSE-2,was significantly faster than world’s fastest supercomputer, Frontier , in molecular dynamics calculations.
Cerebra has also demonstrated that a sparse large language model could perform inference at one-third of the energy cost of a full model without losing any accuracy.
Cerebras ' WSE-2 has a million cores in a very tight package.
It's designed to read memory in chunks, which means taking in groups of parameters at a time.
If a significant fraction of those parameters are zeros , they can be skipped during the calculation.
The problem is that skipping specific parameters is difficult to do on a GPU .
