1) Message boards : Number crunching : What should I ask my isp to determine image file verification (Message 30014)

From http://boinc.berkeley.edu/wiki/Advanced_FAQ


If you get repeated 'bad checksum' or 'wrong size' errors on downloaded JPEG image files, check the 'Skip image file verification' checkbox in your preferences. Typically this means your ISP is using something called UMTS, which does extra compression of JPEG files.


That would be very uncommon (I've seen it on narrowband mobile networks only).

Guys, let me step in. Cancelling WUs was supposed to be conservative (unsent only). If there is a bug - sorry about that, it never surfaced before. I'm having a look.

There must have been a power outage. It interrupted an uptime of more than one year...

Hi JK, thanks for your fix. Your results now seem to work properly. My guess is that it is a bug in the client (not so much the application) which makes the two tasks not isolated from each other.

JK is the only one affected by the problem, as far as I can tell, and it's a nasty one. My guess is that the client does not keep the two WUs separate. Disable as soon as possible.

(Unless there is something more odd like read-only filesystems, file permissions, or the like).

Being valid with such short runtimes is puzzling: thanks for catching it.

After a DB check, it appears that the problem is exclusive to your last two WUs. How it happens, is beyond me, but I think BOINC got stuck somewhere in between WUs.

Downgrading to 6.12.43 did not solve the problem.

Right now, versions seem to be 313.26 (short-term support) and 310.40 (long-term).

Dears, just to let you know: I am experiencing a 20x slowdown on the said driver and boinc 7.0.29 (found in stock Fedora 17's repos; official clients don't work in FC17). Card is GTX 480, CUDA 4.2.

Clock appears to go up normally in the X Server Settings panel, no other sign of problems except this slowdown.

Has anybody had similar experiences?

But it's the right time of day for 'busy with stats'.


Nice catch. I don't think any other oddity goes on on the server at this time. Net congestion is also unlikely, given that it's off-peak in the US.
