I'm only pretending to care

Here's the page from Intel with the full list of participating vendors:

are four 80mm fans really enough to dissipate 1.08 kilowatts of computing power heat

Anything's possible as long as you spin them fast enough; the 1U supermicro phi host has ~1KW in 1.75" cooled by 10 40mm 20K RPM fans.

keep in mind that if your matrices are less than 2Kx2K automatic offload won't work.

I'm tempted to buy one of these just to see how much faster my old MPI jobs will run, compared to how they did on the 4 core Nehalem Xeons I used to use.

Are there any alternatives for people who want a ton of integer cores?

We run SVD on matrices between 500x500 and 10k x 10k, as well as dense / sparse multiplications with upwards of 100mil nonzero elements. Worth looking into just to speed up processing during debugging / design / evaluation of the math involved.

Congrats, you're the one person in a million who should be buying an AMD FX-83xx or a similar Opteron. Unless TCO matters more than hardware cost, in which case cram Xeons all up ons.

If you need to do thousands of integer operations as fast as possible, the Phis or OpenCL devices are still the best options right? I don't really know how expensive Xeon's are, but wouldn't Video Cards be cheaper? Although, is it feasible to make an OpenCL capable FPGA that is integer optimized?

I come from the land of the ice and snow.

So I went to a talk by Ray Kurzweil last week, and at one point he briefly dropped that Intel has working prototypes of self-assembling 3D molecular circuits (which he said he has seen in person) and they are planning to have them replace their current production methods before 2020.

I dug up some stuff about MIT demonstrating the tech about four years ago, and Kurzweil isn't the type to just straight up lie about something like this, but I can't find anything about Intel specifically.

It depends.

I doubt they ship overseas, but got a link?

That ship sailed. They did not ship to while it was up, otherwise I would have gotten one.

EDIT: Current best is 140$. They also don't ship to

Ray Kurzweil suffers from a peculiar delusional belief system which leads him to be wildly over-optimistic (kooky, even) about predictions of rapid technological progress. It truly wouldn't surprise me if someone told him something like "We're loving around with this wild idea for making circuits, but holy poo poo the problems are enormous and 2020 is the earliest we could even begin to ship tiny quantities of engineering sample devices to outsiders, if everything goes perfect, which it never does", and Kurzweil heard what he wanted to hear.

I'm just curious because I'm learning OpenCL for funsies and I seem to have a 50-50 split between floating point and integer operations. Where do you go to learn more stuff about this? I like benchmarks but I don't want to run my own.

Speaking of FPGAs, has there been anything new about the Xeons w/FPGAs since that announcement a few months ago?

He takes like a million vitamins a day hoping to stay alive long enough to have his "soul" uploaded to the "matrix" where he will be reunited with his father. No matter that his father didn't live long enough to get uploaded because the future will have computers so powerful they will be able to extract his essence from the fabric of space and time.

The Amazon Phi deal popped up for a brief while at 92$ shipped. I caved in. Helps that my job will pay for part of it too.

I got a forwarding service box and got it sent to there. No idea how (and for how much) I will get it out of the USA, but one step at a time, I guess. Might be something worth investigating for other non-USA people out there.

Work is about to get awesome. Once I figure out a way how to exactly cool and feed the thing.

Thanks, thread!
