(moderation:
We just ran out of work to be generated for the "Binary Radio Pulsar Search (Perseus Arm Survey)" ("BRP5").
Thus we began to continuously generate work for the "Binary Radio Pulsar Search (Parkes PMPS XT)" ("BRP6").
As the OpenCL app version encounters performance issues with the BRP6 setup, we
- are building a new (OpenCL) application version right now. It should be done after lunchtime (UTC).
- are shipping BRP6 tasks only to NVidia (CUDA) GPUs, until the new app version is out
- restrict the remaining, already generated BRP5 tasks to ATI/AMD GPUs.

Guten Appetit!

For what it is worth:
Received a BRP6 task on a NVIDIA GTX 770 machine. It "bumped" a BRP5 task into "waiting to run" and the BRP6 task is running "high priority". It is showing 55 minutes elapsed and 6 hours 11 min remaining.
[Edit] A NVIDIA GTX 650 machine received a BRP6 task bumping a BRP5 into a "waiting to run" state. On this machine the elapsed and remaining times are 25 minutes and 13:29 hours respectively.
Yep sorry. The first

Yep sorry. The first generated BRP6 tasks still had the 3 day deadline that was only meant for testing. It's now back to normal 14 days.
The new BRP6 OpenCL application version (1.41) that should have the performance issue fixed was issued, BRP6 tasks should now be issued also for ATI/AMD GPUs.

On my ATI 7970 the BRP6 task is taking 2:41 Hrs. as opposed to 2:04 Hrs for a BPR5, running 3 tasks at the same time. Is this the performance issue you are talking about?
RE: On my ATI 7970 the BRP6

No. The performance issue was described in message 138558.
RE: On my ATI 7970 the BRP6

Well, the BRP6 tasks are about 30% "larger" than the BRP5 tasks. The performance issue meant that with the OpenCL version BRP6 tasks ran three times as long as BRP5 tasks. Your report actually confirms that this issue has successfully been resolved, thank you!

An article about an observatory restarting:
Researchers give Algonquin observatory a second life

Einstein@Home may want to check whether they can help those researchers with their search for radio pulsars.

Hi,
from what I gather from the article you linked, the scientists at Algonquin Observatory are observing known pulsars with their telescope (and others at the same time) to study the neutron stars in unprecedented detail. That is not a search for new radio pulsars and very different from what Einstein@Home is currently doing.
Cheers,
Benjamin
