Is anybody else having download problems? I've been trying to download this WU for almost 10 hours and keep getting messages like these:

Sun 08 Aug 2010 07:58:56 AM EDT Project communication failed: attempting access to reference site
Sun 08 Aug 2010 07:58:56 AM EDT GPUGRID Temporarily failed download of 2240301-IBUCH_freebind_pYEEI_100706-19-psf_file: HTTP error
Sun 08 Aug 2010 07:58:56 AM EDT GPUGRID Backing off 2 hr 6 min 31 sec on download of 2240301-IBUCH_freebind_pYEEI_100706-19-psf_file
Sun 08 Aug 2010 07:58:59 AM EDT Internet access OK - project servers may be temporarily down.

I'm not having any upload/download issues with other projects. Since I don't see any discussion of similar trouble here, I'm afraid I might be having a personal problem! :D

TIA,

MarkR

My last result was returned around 9:00 UTC this morning and new ones downloaded 15 mins before so I don't appear to be having problems.

Thanks for the feedback...I must have a host problem of some kind. I rebooted from Ubuntu64 to WinVista32 and had no problem downloading a GPUGrid WU. It's strange, though, as download tests at the same website show virtually the same speed whether on Ubuntu or WinVista.

Probably caused by a temporary Internet issue. If you had aborted the transfer of the failed download, you would have recieved another task.

Right...I've done that and have been downloading another work unit's files for over two hours... :-(

Your latest task status was In progress, rather than Error while downloading. So, did it actually start running on your Linux install?
(Ubuntu64, GTX260-216, Boinc 6.10.56, Q6600, 4GB)

- I see that task is now Aborted by user.

That's correct. There were no download errors -- the files just downloaded extremely slowly. The smaller files would eventually finish downloading, but after many, many hours, of backoffs, "HTTP error" and "project servers may be temporarily down" messages, the larger files never completely finished. So, I just aborted the WU before it ever had a chance to run.

This whole behavior is very strange and I've never seen it before on this host. I do, now, think I have a host specific issue of some kind that I don't understand, and not one related, specifically, to GPUGrid. I tested with other projects and got the same slow downloads. The other projects that are running on this host are doing okay, probably because the data files are small (and don't take long at even 1-2 Kbs).

When it's working on Win32 (this host) I have no problems whatsoever downloading GPUGrid data (or that of any other project). When I perform browser-based download speed tests (e.g. speedtest.net), the results are the same under Ubuntu64 or Win23. It seems like there's only a speed issue working through the BOINC client/manager. I upgraded to 6.10.56 (same as Win32), but that didn't help. I even detached/re-attached to no avail. Unfortunately, I'm not savvy enough to know how to check my Linux install, network settings, etc., to see if it is, indeed, an OS problem.

All I can suggest is the obvious; check your Boinc Mangers Networking settings, Advanced Preferences, Network Usage. Also try to turn off your router/modem (and switches) for a few minutes to allow it to reset at the exchange (dual booting can lead to strange network issues). If it is a NIC driver issue, try installing it again. I’m not sure how much time you want to spend troubleshooting it. Perhaps better to either stick to Windows or do a new Linux install. You could always try FatDog Linux

Thanks for the suggestions. I will do some more checking and see what I come up with. Thanks, again.

...check your Boinc Mangers Networking settings, Advanced Preferences, Network Usage.

Never mind...Sometimes it takes someone else to point out the obvious: the maximum download rate was set to 1 KB/s. If it wasn't for my mischievous, invisible roommate playing tricks on me all the time, I'd guess that I must have inadvertently changed that when I meant to adjust the WU cache.

You may now return to your regularly scheduled programming...<insert embarrassed smiley here>

Does anyone have any idea why I have no GPUPRID tasks either running or ready to run?

You have 4 In Progress (2h after your post).

It may be to do with the way Boinc calculates when you should pick up new tasks to comply with Boinc's cache setting; if Boinc uses the default 0.25days then when you start running a new task you will not always pick one up to sit in cache and wait. It may wait for an hour or so before downloading the task to sit in cache.
