Here is an update and some more details on the third generation GPU core. As I stated before, this core is built on OpenMM, which brings the science further along and allows us to make easier updates. OpenMM supports OpenCL... (...)

Just an update on my blog post. I want to make it clear that we're seeing problems in both of our ATI and NVIDIA GPU OpenCL implementations for OpenMM. Maybe it's on our side (I'm bet some bugs are on... (...)

Simulating protein folding on the millisecond timescale has been a major challenge for many years. When we started Folding@home, our first goal was to break the microsecond barrier. This barrier is 1000x fold harder and represents a major step forward... (...)

The electrical power is out at most Stanford buildings as of 5:20 this morning (Tuesday, Jan 19). SHC Engineering and Maintenance reports that the Stanford Cogen power plant (the power plan that powers Stanford) is currently off line. Emergency generators... (...)

Our main stats web server is being hit with a denial of service-like attack from several machines. They are accessing cgi-bin urls multiple times per second per IP, which is slowing down the web server for everyone else. We have... (...)

Looks like the stanford main web servers (including those which host the main university page www.stanford.edu ) are down or very slow. We've filed a ticket. Note that the stats pages on fah-web.stanford.edu are run on a separate system and... (...)

We have been working to track down the nasty bug on the NVIDIA GPU WS's that is causing problems for donors sending back WUs. We have been trying different fixes over the last week, but this has been very tricky... (...)

Here's a heads up for donors running with clients configured for small WUs (v6 clients) or normal WUs (in pre-6 clients); note that this does not affect "big WU" client configs for v6 or earlier. It looks like we're running... (...)

Joe has been pounding on the v5 WS trying to shake it out from the recent disaster with problems returning NVIDIA GPU WUs. The upshot of all of this is that the v5 server code was pushed hard in many... (...)

It is looking like the WS bug fixed has helped resolve the NV issue GPU work server issues. We are keeping a close eye on things, but it looks like the situation has been stable so far. (...)

There have been some questions about the server status for Folding@home. The problem from the donor perspective is that the lack of WUs looks very similar to the servers being down -- the client reports it can't connect to the... (...)

Folding@home researcher Greg Bowman was awarded the 2010 Kuhn Paradigm Shift Award from the American Chemical Society (ACS) for his talk on two paradigm shifts resulting from Folding@home: 1) the new methods that Folding@home uses to simulate protein folding, misfolding,... (...)

We will likely be taking an ATI GPU server (vspg2v2) down today for maintenance. We are working to get more jobs on its sister server (vspg3v2) to avoid WU shortages, but we're giving a heads up for donors just in... (...)

We have been working behind the scenes to optimize the Folding@home GPU client for the new NVIDIA GTX 4xx hardware. So far, it's been going well with us hitting some strong performance numbers. We are internally testing this and hope... (...)

We had some WU shortages over the weekend, but for the most part handled the biggest demands. However, we still have shortages for certain types of WUs, especially for pre-v6 clients. We are working to add more A3 WUs as... (...)
