About a year and a half ago, HP was recruiting Computer Engineers at my school. One of the engineers who worked on the Foster core gave a presentation about the guts of it, and about its history. He told us that basically, because Intel had done such a poor design with the current core, that they went to HP and hired them to completely re-design it. The engineer told us that Intel would be using the Foster core, rather than the now current one, for the next generation of their chips, from the Celeron-ish processors to the high end models with lots of cache. Apparently, Intel has a lot more faith in this new design than their own, so maybe we can expect good things and fewer problems in the future.
I recently bought an ASUS K7V and a 700 MHz Slot-A T-Bird, and am having similar problems to those described in the article. Whenever my system is loaded with a CPU & Memory/Disk intensive process, the power to my machine cuts out. No OS errors, no lockup, just power cutting out. Once in a while everything just freezes.
I think that my 250W power supply just can't cut it when the IDE channel and CPU are heavily loaded. I thought that maybe it was my memory crapping out, but when I replaced my T-Bird with an Athlon 500 Classic, no problems at all, so I believe that my power supply is the culprit.
I read that the T-Bird can suck up to 80 Watts alone, but I'm not sure how reliable that figure is. Now I'm probably going to get a nice 350W power supply and see if that fixes the problem. If not, back goes the Slot A T-Bird. Anyone know where to get a good power supply?
Thanx.

I work for Dr. Eric Halgren, one of the 'head';) researchers doing this work, and I was totally surprised to see an article about work on/.!
I didn't have anything to do with the programming side of the analysis, but I was one of the lucky ones who worked on getting the programs to run on our Linux boxes. The boxes that I did alpha testing with were two Dual Pentium-II boxes running a fairly standard install of RedHat. When I started working there I was a complete Linux newbie, and struggled with the setup, but this work got me interested in Linux and now I love using it! I believe that they have a Beowulf of Linux machines to do the crunching now (no, this isn't a 'Beowulf' troll, honest!:).
The simplified version of what they're doing is creating 3D representations of the human cerebral cortex from structural MRIs of research subjects, inflating the surface of the brain so you can see inside the folds, and then mapping MEG data of the research subjects to the generated 3D surfaces using a process called "anatomically constrained magnetoencephalograpy" (aMEG). This brain activation data is mapped to the surface at about 5ms intervals, and is represented graphically on the generated surfaces to make "brain movies," on the SGIs (I think the movies now or will soon work on Linux). Dr. Halgren and others then analyze these movies and publish their findings.
They also do some analysis of severly eplieptic brains, in hope of better understand them before and after brain surgery, so that scientists can better localize problematic areas of the brain so less brain tissue can be removed in future surgeries. It's really a quite fascinating combination of different technologies and medicine, in my opinion!
Rather than trying to further explain the research with my limited understanding of it all (I'm certainly not a neurophysiologist!), for more details about the research being done with this technology, you can read the websites (two of which I designed:) for the project. These sites are:
There are a few of these "brain movies" and thorough explanations and publications about the work available there.
I work in Salt Lake city, and Dr. Halgren has recently moved to Boston to work for Harvard at NMR MGH, so I am a little out of the loop on the current state of the research, but I hope that this answers some questions about this.
May my boss forgive me if I've said something totally inaccurate, but I wanted to give you an overwiew of what's going on.
Grr... Windows just crashed on me while I was watching a DVD and finishing posting a reply, so this is the condensed version of what I was saying, with regard to future Macrovision copy protection and whether or not the MPAA is thinking ahead to HDTV:
The other day at Sears, I overheard an HDTV technician telling a sales rep that the current model of a certain HDTV decoder boxes with connectors for digital output of the decoded video stream was being recalled, and the next generation would be shipped without the connectors. He said that the reason for the recall was because "Hollywood" had told the manufacturer that this connection made it too easy for people to make copies of HDTV broadcasts too easily. (I am assuming that Hollywood==MPAA & movie studios.) Obviously, "Hollywood" is thinking about the future of digital entertainment and is taking aggressive steps to place as many obstacles as possible in the consumer's way before the consumer realizes what has been taken from them. This disgusts me, and I only wish I had the money to buy one of the decoder boxes with the digital output before they are gone forever!

I wonder if they'll put Linux-compatible modems in Thinkpads now? :) Is my 1st post really 1st?
