I guess any project has its defined goals and thus has its own terms. Or are we slowly "assimilating" with Seti@Home aiming just to look at the sky as long as it will be possible?
And I forget to ask, are there any plans to look at the Southern hemisphere, using for e.g. Paul Allen's telescope?

I don't quite understand that question. The primary goal of Einstein@home is the search and analysis of gravitational wave, and as far as I can foresee this search will continue for the next decades.

The data analyzed in BRP5 (and earlier BRP3) comes from the Parkes observatory in southern Australia, which is looking at the southern hemisphere. Arecibo is close enough to the equator to cover a large amount of it, too. AFAIK The "Allen Telescope Array (ATA)" is located in California even north of San Francisco, I don't think it will see much of the southern hemisphere at all.

Ok. I undestood. This means that BRP4G is endless, because we can not say exactly that for e.g. some sky partition is already thoroughly studied. There's always some space for further researches.

I'm sorry. I made a mistake thinking that Australian observatory is an ATA.
I surely need to travel there in order to get acquainted with it :)

The ALMA array is operating

The ALMA array is operating at 5000 meters height in the Atacama desert in Chile and its workers have gone on a strike demanding better working conditions and more pay. But I don't know if its frequencies are suitable for a pulsar search.

For the BRP4G-opencl-ati application, my system has 24 valid, 28 pending, 2 invalid, and 2 error for tasks so far.

Thanks for reporting, the two error cases actually seem to point to a server-side problem.

Thanks for the info. I have been seeing as many as 5 BRP4 tasks per day that are coming back as invalid. I have gone through my hardware setup and tried to underclock the GPUs, CPU, and even loosen the timings on the memory but the invalids keep occurring daily. I ran a Memtest and other GPU stress testing which came back good. From the testing I have done, my hardware appears to be running stable and temps are well below maximum for all hardware.

My system would get an invalid task every so often with BRP5 but significantly more with the current BRP4 tasks. I plan to swap the CPU with an Intel 4930K when available so that the CPU will be new and perhaps that will help in the event this is still a hardware issue.

Jeroen, I have seen exactly

Jeroen, I have seen exactly this same behavior on one of my machines. Two machines, one almost the exact same setup, have no problems. Like you I'm at a loss as to the reason.

It seems like more "beams to analyse" have been added to the server status page. 67431 now.

That is correct. We have been receiving more data from Arecibo via Cornell in the last few days.

Happy crunching!

For the remaining +/- 4000

For the remaining +/- 4000 beams BRP4 remaining, what is the ratio beetween beams available for the gpu application and for the cpu application?
