Update on Win/SMP client development

NEWS TITLE ::
 Update on Win/SMP client development
NEWS INFO ::
The Win/SMP 6.22 client has been showing several issues, namely:
bad EUE behavior (quits rather than moves on)
no ACK sent issues
core 0x7b errors

We've been working to take these issues one by one and have some progress to mention.  For issue #1 (EUE), we've released a new client (6.22r2) at http://foldingforum.org/viewtopic.php?f=46&t=4764 .  If this looks good, we'll roll this into 6.23.We also had a meeting to see what's up with the ACK and have an idea there too.  That will take a client mod as well and that's been coded and is starting to enter Stanford QA, then alpha testing, then beta testing.  This client mod may also be relevant for the new GPU clients as well.The third issue is still a little perplexing since it is a core issue and in principal shouldn't come with a client update.  Now that we think we may have got the first 2 issues resolved (or at least a patch to test), we're moving to deal with this third issue. I should stress that it's by no means guaranteed that the first two are solved, but we will need more testing to know for sure.We'll give more news as we know it.

Update on GPU2 servers & upload issues

NEWS TITLE ::
 Update on GPU2 servers & upload issues
NEWS INFO ::
We've been looking into what could be the cause of the GPU2 upload issues people have seen.  We have some ideas and that has resulted in new server code and a new client.  The new server code has been tested on vsp07 and is now rolled out on the other GPU2 servers (vspg1, vspg4v2, vspg3v2) and we're monitoring it.The new client (dubbed 6.20r1) is now undergoing closed beta testing.  If that checks out, we'll release it for open testing.  The new client is the key part of this fix (new client + old server code is probably ok), but the new server code will help a little.  Also, the new server code is useful for the stats change over (described below, where we separate out NVIDIA from ATI stats).  Note that the osstats page will be screwy for a while during this switchover.

 Update on GPU2 servers & upload issues, part 2
NEWS INFO ::
The new server code has been in for about a day, and so far so good.  The netloads are very low on the servers and everything appears to be behaving well from our side.We have also made a new client (6.20r1) available to improve uploads.  The client patch should be a greater aid than our server patches, so if you are having upload problems, please consider giving it a try:http://foldingforum.org/viewtopic.php?f=50&t=4806

Distribution of the GPU2 client

 Distribution of the GPU2 client
NEWS INFO ::
We've worked with commercial partners for many years now, including Google (Google Compute Client), Sony (PS3 client), ATI (GPU1, GPU2), and NVIDIA (GPU2).  In the past, we've allowed Google and Sony to distribute FAH clients in order to try to boost the size of FAH and get more donors.  We've decided to allow NVIDIA and ATI to do this as well.  We hope that this will boost the use of GPU2, which is relatively small now (~10,000 clients), but we have high hopes that it could grow more (maybe to 50,000?).To make this issue clear, we have updated the EULA on our web page and main FAQ, and we will update the EULA document in subsequent clients as appropriate.

 GPU2 WU's in "production mode"
NEWS INFO ::
As of last Monday, the GPU2 projects (both NVIDIA and ATI) have been in production mode, which means that we've moved on from testing to direct research on them.  The ATI cards have bee in production for a while (more than one month before) and we're starting to write our first peer reviewed scientific paper deriving from the results.We're very excited about the GPU2 possibilities right now, since we are getting incredible production from GPU2 clients.  Once the first paper has been formally accepted by peer review, I'll talk more about the results.

One of the stanford nets appears to be down -- IT is looking into it

 One of the stanford nets appears to be down -- IT is looking into it
NEWS INFO ::
We have 4 different server rooms for redundancy and it looks like one of the room's network is down.  All machines on the 171.64.65.XX net (VSPG*.stanford.edu) are unreachable right now.   [Note that this server room is in the Stanford Computer Science building and it looks like the whole Stanford CS net is down (eg http://www.cs.stanford.edu/ is unresponsive).]  We have notified the network admins and the server admins and they are working on this right now.  It's Saturday, so they're on a reduced staff, but they're on it.  This is something beyond my group's control (much like an electrical outage or a major natural disaster) and we have to wait for the Stanford CS networking gurus to do their magic. The good news is that much of FAH is still up.  You can see what parts are up vs down on our serverstat page (http://fah-web.stanford.edu/serverstat.html).  However, the bad is is that with many of the key machines unreachable, the other machines are heavily loaded at the moment.  Once the additional server room comes on line, then everything should ease up.It's very unfortunate timing that this comes shortly after a rough set of weeks with our complete server upgrade, which lead to several machines being down in a rotation for updates.  That lead to servers being hit hard too.  Note that we have been working to improve client/server performance under such high loads.  That development lead to server code changes and a new client binary available that helps uploads to servers when the servers are loaded.  Please see the previous posts here for updates on those clients.

It looks like the down net is coming back up now.  The servers will be a bit loaded while everyone tries to put results back, but it should work itself out soon.

 Massive power outage

Palo Alto is having a massive power outage which has brought down much of Stanford too. More info to come.

We will try to get this up asap once we get power back but it will be rough for a while.

 Coming back on line
NEWS INFO ::
Here's the update from StanfordPower mostly restored to campusUpdated 3 p.m pacific time. - Power has been restored to the majority of the Stanford campus. All normal power is expected to be restored by 5 p.m. or sooner. A major outage occurred today at 11:30 a.m., affecting P G & E customers in Stanford, Menlo Park, Atherton and Palo Alto. If you are still experiencing difficulties on the Stanford campus, call 723-2281. At Stanford Hospital, dial 286.This one was a major disaster at Stanford and Palo Alto (and nearby cities), probably the biggest outage in a while.  However, there seems to be some major Stanford power outage once a year, which is a major problem.With this in mind, we have been distributing more of FAH to outside of Stanford (with servers at UCSF, Columbia, Cal State U Long Beach, and U. Pittsburgh). We hope to have a European site soon. Once those sites are a bit more established, we'll see about pushing an assignment server to a non-Stanford site and we should be much more safe to Stanford-related issues.Also, it's good that we have servers in 4 different server rooms on campus.  One stayed up the whole time, two came up fast, and the fourth (VSPGxx) is coming up now.  Some servers will be slow to come up, so we expect this may take at least a few hours.  The stats update has been turned off until this gets sorted out.  We hope to turn it back on later tonight, but it may have to wait until tomorrow morning.

 Update: almost 100% back up, but stats update on hold
NEWS INFO ::
Most machines are now back up with a few exceptions.  One key exception is a server used in the stats updates.  So, while the points are being recorded on local servers, these logs are not being inputted into the stats at the moment, i.e. stats updates are on hold at the moment.  We will give an update when the stats update is back on line.   Please keep in mind that the points are not being lost, just not being entered into the db and once this machine is up, all the logs (and all the old points from last night, etc) will be entered into the stats db.
