FAH SMP Affinity Changer

Have you heard of the FAH SMP Affinity Changer? It’s a little program that monitor the process of the FAH client for each core and will redistribute the FAH process accordingly in order to achieve maximum performance for the SMP F@H client!

Here’s some before and after results from me from the Core2Duo processor running a single WinSMP client:

One thing is, it only works with a C2D processor running a single WinSMP client or for a C2Q processor running 2x WinSMP clients. But if you are running a single WinSMP client on a C2Q, it will not have any performance gain on it!!

New PS3 Client!

SONY has released an updated client for the PS3 that is supposed to fix the recent PS3 client/server issue.


Starting today a new version of Folding is available. This version is a minor fix to the previous 1.3 version and adds a better tuned algorithm that handles peak performance hours of Folding@home network, by acting differently to certain network errors if those occur.

It is recommended that you update to the new version by quitting the application and restarting it. Your current WU will not be damaged in any way, in-fact Folding will continue from the exact point you have stopped it.
Please also check the official Sony Folding site here:

We can already see a stabilized network activity for the last 5 days. With the new update we are certain that the network will continue to be stable for good.

At this point I would like to thank people again for being patient and continue to donate to our project while Stanford & Sony was working on the fix.

WinXP SMP Beta Client expiring Feb 1st

We can all be watching out for the new clients,which will be released soon. The expiration’s dates on the new clients should last longer due to their maturation. The old clients will continue to work even past their expiration unless restarted, at which time the new one will need to be downloaded.


F@H Code Development Update

Here are some code development updates on some important client/cores from Dr. Vijay!
~ GPU core: we’ve got the GPU core running in house and we found and fixed some bugs in our Q&A stage. We’re now continuing Q&A to see if we find any more bugs. Right now, the GPU core is running on all new ATI cards, so we’re excited to roll it out. We are using CAL now (ATI’s hardware abstraction layer) and that seems to make life a lot easier, and also should make running a GPU client a lot easier from the point of view of donors, as the driver issues and complexities should now be resolved. We are still looking into an NVIDIA client. The NVIDIA GPUs are very different to program, so a port isn’t a simple thing to do. We are looking into this, though.
~ SMP core: right now, SMP on Linux and OSX is behaving fairly well, whereas Windows is giving some issues. This is perhaps not a surprise, since the SMP code must use MPI, which has its origins on UNIX and is a newcomer to Windows. We have been working with Windows MPI developers to improve the situation, but they tell us this isn’t a simple fix. Since we are in the business of studying proteins, not writing MPI libraries for Windows, we will wait until the MPI experts improve the Windows MPI before we make any claims of improvement there.
Finally, beta clients will be expiring soon (in Feb 08′ I believe), and we are in the process of Q&A for new clients. We will also extend the expiration deadlines in the future clients to give some more time, and since the clients are appearing to be maturing.

F@H stats updater for iGoogle

Due to some others request, I’ve also made a EOC F@H personal stats updater for iGoogle!

It works the same as my other two F@H personal stats feeder (Vista Sidebar & Yahoo Widget).

You can grab this gadget from HERE. And if you have any question, you can post it in this support thread too.

Hope you’ll like it!
