Sorry, for the delay in response, I've been away.

    Like most folks I have asymmetrical file transfer service: download @12~14Mbps with burst for large files, & upload @4~6Mbps (bits not Bytes), raw data.

    Over the past five years, across thirteen BOINC projects, I've noted result file upload throughput nearly always above 150KBps, sometimes 2-3 times that. This includes CPDN, which uploads large intermediate result files (~26MB) daily. It also included GPUGRID until a couple of months ago. (<30min to upload a long queue result used to be typical for me.)

    5KBps to GPUGRID and 200~300KBps to 4 other projects simultaneously over several hours does not suggest a chokepoint at my end of the route.

    I recently ran 3 traceroutes to the IP provided. All were ~220ms at the distant end, over 18-19 hops. Not great but not too bad. Times to the end of my ISP's segment of the route were 10~12ms. Traceroute test packets, however, are not the same as file data transfer packets that the server must process instead of throwing away.

    I reiterate that this is not the first thread in this forum to raise the upload speed issue.

    shauge reported a similar problem here, and that's 2 datapoints. I suspect there are others who haven't followed this thread and/or haven't bothered to report.

    File transfer problems do not necessarily affect all users at all times.



It might be worth asking the community to "please report if you are experiencing slow resultfile uploads." You may be surprised at the response.

Best wishes to all for the New Year.

Good news GDF, but slightly off-topic. My query is about speed (actually lack thereof), not size ;)

Best wishes.

I'm 7+ hours (and 75%) into upload of a 91Meg result file at ~5KBps, with several stalled connections. In the same period, I've uploaded 40+ results to other projects at a more normal ~150K. This issue has been discussed before in this forum.

¿Que pasó?
4) Message boards : Number crunching : Beta WU crash (Message 27533)

FYI, in addition to info in stderr for failed beta task 6148000:

The task crashed the NVIDIA driver (306.97) twice, the second time fatally (for the task). The H/W & driver recovered both times, and BOINC handled the crash. The GTX580 was running at default clock rates (GPU=797MHZ, Mem=2025MHZ) which I always use for GPUGRID. It appears the application was intolerant of other activity by the GPU, such as opening/closing a window for another application. Not great on a multitasking system :(

Computer ID 57387 has successfully run v6.16 WUs with this same driver, as well as thousands of Primegrid, Poem & Milkyway tasks (at moderate overclock).

Best wishes.

This problem appears to be back--5.4KBps upload speed. Five hours to U/L one result file is a bit much. I stopped & restarted upload several times to make sure it wasn't just one sour connection (nope).

Ah! Another warm day (29C) in Southern California, and another vacation for my GTX 580. GPU load is ~65%. Thanks Noelia :)

My gpu's were bought to work, not take vacations! Such a low gpu utilization means extremely low points are awarded, which will not make it worth running for many here (including me)


Chill Stoneageman, it's betatesting. To each his/her own ;)

Thanks Noelia.

These tasks are like a little vacation for my GTX 580, since the GPU load is only 15~30%. It's a warm day here in Southern California, and we are running 15 deg(C) cooler than the usual 77~78 deg with Primegrid's GPU apps.

Three completed successfully so far :)

Best wishes

Any news on the avatar upload conundrum?
