As a follow-up - it's one DDR3 channel - maybe 2. That puts it at about 1/30th of a K20.

People have tried to creep into Scientific Computing with processors like this (tile-based perf-per-watt SoCs). They haven't succeeded (see: Adapteva, Tilera, etc.). And they have much bigger budgets. :)

For the record, the Tesla K20x TDP numbers include the memory (it's for the entire card).

A comment below says that it uses DDR3 1333. Total bandwidth of that, being extremely generous and giving them 6 memory channels (unlikely) puts you in the neighborhood of about 1/10th the memory bandwidth of the K20.

Combine that with the "how do you connect this to other things" problem, and this chip has no chance in scientific computing.

Submission + - University of Minnesota Launches Review Project for Open Textbooks

Durinia writes: Minnesota Public Radio is running a story today about the University of Minnesota's Open Textbooks project. The goal of the project is to solicit reviews of college-level open source textbooks and collect those that pass muster onto their website. The project will focus first on high-volume introductory classes such as those for Math and Biology, because as David Ernst, director of the project, states in the interview:

"You know the world doesn't need another $150 Algebra One book. Algebra One hasn't changed for centuries, probably."

If it wasn't for Newton, we wouldn't have to eat bruised apples.

Working...
