No, its not possible atm.
It would require new science apps.
Joe, Raistmer and or Jason can explain this much better.

My understanding is that the SETI analysis is not conducive to paralleling. I'll leave it to the Lunatic Pros to chime in.

What do you think we do on GPUs? They are parallel devices, par excellence.

SETI probably isn't appropriate for the old-style symmetric multi-processor (SMP) style of parallel programming, but it's been suggested that OpenCL could use multiple CPUs in the same way that it uses multiple compute units within a GPU.

For traditional (x86-style) CPUs, there probably isn't any point of incurring the extra overhead of the middleware - we have efficient enough CPU applications to perform the work required in a timely fashion on single cores.

If OpenCL drivers/runtime support are available, there might be some benefit of from running multi-core applications on Atom and similar devices, which might struggle to meet deadlines in single-core mode. Recent versions of BOINC already have the capability to schedule OpenCL on CPUs, though I'm not aware of anyone testing that facility yet.

John over at Collatz does have a OpenCL CPU app available.

The trouble is that all these people work for foreign call centres where your own countries legislation has no legal effect. A lot are in Eastern Europe or the far East. The local governments there have no interest in stopping it because it brings income into their country.

Modern phones can block all "number witheld" and "international" calls from getting through. I only give my mobile phone as a contact point not my land line, I also registered with the TPS, and am ex-directory, it all helps. But as more and more people buy online via the web, more people give their home number, and don't tick the box "don't pass on my details to associated companies".

The problem with that is most of them use IP based phone numbers so they can show as calling from anywhere they want.

I have gotten only a little bit of rain so far.

With rain comes the Tulefog. Not to bad yet. The sun is said to make an appearance today. We shall see.

Here are some stats

And accidents too, I lived in Tulare CA for a bit, so I know.

I always preferred Tulelake, CA.

Eric posted a new thread in the Technical News area.

It is offline for at least the weekend and probably longer.

Well the weather here is sure not delightful, as this radar pic shows, the orange dot is where I live at... Temp outside is: 47°F/8°C with Light Rain...

And heading my way next.

OOCH. I some leakeage here too, but have a seperate shut off valve, so I still have my indoor water. Will deal with that in the spring.

Anyway, none of the bad wind that was forcast yet, but the streets are starting to flood.

Luckily I don't have to deal with a sewer bill here.

I have no shutoffs inside except for the toilets, so to fix anything I have to turn off all the water.

Oh Wow. 15 Years. Gone by fast with so much progress since....though I still miss the cool factor and simplicity of the classic screen saver running on my old Pentium 200MMX w/ Win95 :P

Greetings and cheers in no certain order to: Josef W. Segur, Tetsuji Maverick Rai, Alex Kan, Mathias Pilch aka Crunch3r, Ned Slider, Harold Naparst, Hans Dorn, Simon Zadra, Ben Herndon, Jason Groothuis, Raistmer, Urs Echternacht, Richard Haselgrove, Arakyn, and everyone else I've had the pleasure to share this fun hobby with over the years. I hope this finds all of you well and with best regards for good health and cheer this Christmas season!!!

Best to all,

You still have your old iMac I see, mine died of abuse a couple of years ago.

Most likely Monday I get to do some outdoor plumbing with the help of a neighbor.

I have a leak on the main line that needs to be fixed as it is leaking about 7500 gallons a month currently.
30) Questions and Answers : GPU applications : Postponed: Unsupported OpenCL runtime - since Driver update. (Message 1612010)
Posted 11 Dec 2014 by Profile arkaynProject donor
Hey guys...I have read what I could on this topic but still need some clarification if I can get it.

Running a HP Pavilion DV7 (only run Seti in BOINC) with a Radeon 7470M HD card. There have no graphic updates to this machine. The on board drivers are AMD 8.882.2.3000 dated 9/30/2011. Seti has run everything flawlessly since the machine was new two years ago. However I did the BOINC 7.4.27 (64) update yesterday and now all the AstroPulse V7 work units are giving me the "Postponded Unsupported OpenCl runtime" warning. All the non-AstroPulse work units are running fine. Also not sure how to dump Postponed units. Today I just just deleted SETI from BOINC and rejoined and it downloaded non AP units but now I see I have two more none working AP units back.

Do I need to update the drivers? (which I hate to do as this is a work machine and its its perfect as is) All the threads talk about going BACK to a working driver but there have been no updates to go back too. Also this just started once I did the BOINC update.



That was an attempt to limit errored work coming back in. It was revoked in later builds.

Try this one instead.

AP is back, time to get those RAC's back up.

Ugh, these people have the luxury to only work when the sun is up? Bah!

When I'm at work at 8am this time of year at the Northern Hemisphere, there's not been a sun in my life yet! If it wasn't dreary as today, it usually is down as well when I go back home at 4.45pm. I'll have to wait till end-of-January to be able to see the sun still at the end of the day.


Sunrise Tuesday 9th : 9:45am, Sundown Tuesday 9th: 2:55pm. Length of the day: 5 h 10 min.

And I wonder why people think that us Finns are grumpy people ;)

I'm glad that we're getting rain here and not what they got a few hundred kilometres WNW from here. :-O


That would be called a Haboob, very common where I live.

Vic, is that first ornament supposed to be Mercury or the sun? If it is the sun, it is way too small. If it is mercury then that means the last one is Pluto. Sorry Ulibelle and Rob, but that one has to go!

They are working on defining Pluto as a planet once again.

Time to get out those keyboard shortcuts then.

39) Message boards : Number crunching : PC suddenly shuts down (Message 1605807)
Posted 26 Nov 2014 by Profile arkaynProject donor
2 days or so ago my PC began shutting down, I can't turn it on again but 1-2 mins later it starts up again by itself. I thought it might be my UBS doing something since there was a red light flashing so it connected it directly to AC, it ran with no problem since. But today it shuts down again, any idea what it could be?

Could be overheating the processor, or a problem with the PSU.
40) Message boards : Number crunching : EVGA NVIDIA GTX275 - Crunching Options...???... (Message 1604945)
Posted 24 Nov 2014 by Profile arkaynProject donor
Doing further reading in the Thread linked by Zalster, I have found that the latest BOINC may also limit me... Something about the latest versions of BOINC seeing the GTX275 for what it is; and, how old it is, and will prevent AP's from being downloaded to the system...

If this is the case; which BOINC should I use for this system??? The oldest BOINC I have downloaded on Exeter, (the system with my GTX760), is 7.2.42. If I go to my laptop, Voyager, I'm sure I can find older than that; however, I don't want to go back too far, just far enough that I will get AP v7 work for the GTX275.

Thanks again everyone. :-)

You can get any version that you want from here.;O=D
