I think the issue is that grandpa has folded a LOT of -bigadv work units both v7 and v6. v6 to stanford or sweden has no problems, v7 to Stanford has no problems, but v7 to Sweden always has problems.

I'm testing to see whether v7 has the same issue as me, but I only have one bigadv machine and it's only an i7 @ 4.2Ghz, so my collaboration takes time. While a simultaneous upload would be nice, I don't think it proves anything that a constant repetitive outcome doesn't. The same results time after time is just as scientifically relevant, plus it removes any interaction between the two clients. The bottom line is there is something different about v7 uploading to Sweden, either because of the client uploading over such a distance, or the server somehow handling the two connections differently.. What would be most useful is if someone at Stanford could drop a message into the thread to discuss whether v7 handles uploading differently, so we can narrow down what we're dealing with better.

Well that is mighty suspicious. I have never had an issue uploading -bigadv with v6 EVER - always maxed out my ADSL2+ connection @ ~60KB/s, to the point of being unable to skype etc because nothing gets left for it (great for getting results back fast). But with v7... well, you can see the results below. Looking at my mrtg logger, UL is stuck on ~31KB/s (max 31.9 kB/s) and takes just short of an hour to upload everything to Stanford. So compared with grandpa, different client location (New Zealand) different server location (California) similar distance, same effect.

Just to be clear, my ISP employs none of the comcast-type shaping and rarely if ever has had international traffic congestion as it owns the pipe between Stanford and myself (possibly the only benefit of a 20GB monthly cap, of which I'm still well within). I was pretty adamant to start with that it was a networking issue (sorry grandpa) but I am firmly sure it's a v7 + bigadv + distance problem now. Whether that's due to a client upload method or a server issue.

I'm happy to continue running bigadv work units on v7 to test this, but there is definitely a connection between v7 and capped -bigadv across long distances such as trans-pacific or trans-atlantic.

My time is very limited right now. Would somebody tabulate the various reports, sorting the data by V6 vs. V7 and by Donor so we can see what patterns emerge. That should be a lot easier than my proposed tests.

Apologies for wandering a bit off topic, but I don't think the upload speed issue is confined to folding-2.pdc.kth.se + v7 + bigadv only. Looks like I can reproduce this quite easily with v7 when uploading from Finland to Stanford, GPU3 & classic WUs both. If you consider it worthwhile , I suppose I could babysit my rig this weekend and set up e.g simultaneous uploads with v6 GPU3 client and v7 GPU3 slot, or some other test someone might devise. You provide the numbers, I'll do the painting. :wink:

Hard to find a specific pattern, but from what I've gathered, when this supposed throttling occurs, v7 upload speed is capped at ~30kBytes / s for everyone, right?

I did have in the back of my mind your results Napoleon. I suspect the issue is most obvious for bigadv because it is spread out across a long period of time (an hour at 30kB/s). I might have done my maths wrong when calculating the upload speed of my regular SMP work unit on v7, because it was such a small work unit.

I think the best testing at this point in time would be alternately running v6 and v7 (perhaps every other day, I think swapping every single work unit would be overkill) and just keeping a running log of upload duration, size and speed. That way if we see a pattern develop, time after time, it should be fairly decisive.

I'll go ahead logging all my work units (I still have the logs).

For the purposes of testing this I'm going to set my i7 to run two standard SMP clients (one v6 one v7) in -smp 4 mode, non-bigadv as soon as I get a Swedish bigadv work unit for v7. It appears that the issue is across all v7 work units. I might change this further and fire up my ATI HD4770 GPU...

Obviously living in New Zealand I'm on the other side of the world from all of the servers, so if someone from the US is able to replicate my tables using bigadv to CA and Sweden (I think bigadv is the only one which will allow this?), that would be ideal. Also if anyone in Europe was able to confirm my stats to Stanford, and anyone in the US was able to confirm that it operates at full speed would be great.

I note that at this stage all my v6 work units are to Sweden and all my v7 work units are to California, but I will update this table once I have got some Sweden data for v7 and some CA data for v6.

Below is an image of my current personal table (click to enlarge), if someone wants to add to it... Note both Alpha and Delta are on the same LAN accessing the same internet connection.

Here is my latest 6901 sent to Sweden using Linux v6 a grand total of 6 min. and 9 sec. it is pretty obvious there is something wrong with the servers in Sweden when it comes to v7 and 6900 and 6901's. What more is needed fore somebody to look into this. I have made multiple post showing the difference and it has been confirmed by kiwi. Just simple deduction will suggest there might be a problem. :eo :ewink:

Based on the data from k1wi, it looks as if v7 reports ~2x slower upload speed than v6 regardless of the work unit.

Re: #682 folding-2.pdc.kth.se: Noticeable V7 slowdown

Postby jcoffland » Thu Jul 14, 2011 1:58 am

I've been investigating this problem in more detail. The main difference between v6 and v7 client socket communication is that v7 uses non-block socket operations. This makes it easier to interrupt a transfer and shutdown gracefully.

However, we might be getting hit by the problem described here: http://support.microsoft.com/kb/823764

I'm going to decrease the block size that the v7 client tries to send at one time, as suggested in the above article, to see if that will solve the problem. From reading this thread it seems the problem occurs in both Windows and Linux. Is this indeed true? k1wi's data is the most conclusive but seems to be from Windows. It maybe that the issue described in the above article affects both Windows and Linux since they likely use similar implementations.

This is difficult for me to test so I'll have to ask you guys to test it out in the next release.

No it does not occur in Linux at least not on any of my machines but they are on V6 Will Linux V7 now get 6900 and 6901 WU's if it will I can test it .

Postby k1wi » Thu Jul 14, 2011 11:25 am

Unfortunately I am offsite for the next couple of months so cannot do any extra playing around with clients (currently just remotely monitoring them).

My experiences with the clients were that distance is a factor, so it is hard for people 'close' to the server to replicate it and it doesn't matter so much for the uniproc work units (because they are so small anyway).

k1wi

p.s It is great to see a potential solution to this.

I wouldn't expect that Windows and Linux would be the same without further qualifications. The entire stack was rewritten somewhere between WinXP and Vista. There have also been some changes to the Linux stack but I'm not knowledgeable enough to specify which nucleus reflected the changes.

I can now confirm that the problem is not present on Linux. I uploaded a 6900 and a 6901 today on Linux rigs running v7. It only took 6 min to upload the file to the server.

Re: #682 folding-2.pdc.kth.se: Noticeable V7 slowdown

Postby toTOW » Tue Jul 26, 2011 10:30 am

I didn't read the whole topic, but the problem looks very like the one I have with V7 client and ATI Core 16 server : it never uploads faster than 30 kB/sec ...

I'm pretty sure it's a v7 issue ...

Which OS are you running?

I don't think you mean V7, but rather V7 on WinXP. Those who run Linux/MacOS/Vista+ don't report the same problem.

Based on the previous post by jcoffland, he's going to fix what's covered by the Microsoft ticket. From the perspective of that ticket, note that:
