Intel researcher Timothy Mattson talked about the feasibility of processors with 1,000 cores at last week's SC10 conference:
The architecture for the Intel 48-core Single Chip Cloud Computer (SCC) processor is "arbitrarily scalable," said Intel researcher Timothy Mattson, during a talk at the Supercomputer 2010 conference being held this week in New Orleans.
"This is an architecture that could, in principle, scale to 1,000 cores," he said. " I can just keep adding, adding, adding cores."
Only after 1,000 cores or so, the diameter of the mesh, or the on-chip network connecting the many cores, will grow to such an extent that it would negatively impact performance, Mattson said.
