Breaking mirror symmetry in HPC

If you are not already reading HPCWire on a regular basis, I do recommend it as one of the “must” weekly aggregation sites. They have an interesting article on the “coming” heterogeneous computing systems. Neat idea, but heterogeneous supercomputing systems are already here. Have been for a while. In massive numbers. Working on specialized HPC problems. More about this in a moment.

APUs in the news

Referencing this article.
When we talked to a few VC’s previously about APUs, we were asked to show that there would be demand. Kind of hard to do so in advance of the market, but we made rough estimates. Earlier this year, ClearSpeed took its reference design board and started selling it. Sure enough people bought it. Because it does a number of things quite well. At a lower power consumption.

A teraflop here, a teraflop there, and pretty soon you are talking about real computing power

It seems IBM will be building another new NNSA machine. So whats interesting about this, other than IBM getting good press? Well this appears to be part of a growing wave of heterogenous high performance computing systems. Roadrunner appears to be a mix of COTS Opteron hardware, and Cell based blades as Accelerator Processing Units (APUs).
