It would seem that this project is not seeing my GPUs I have reset the project to no avail, I have detached and reattached with the same results nothing. so I guess I can not run this project.

Looking at your computer page, it does show that you have 3 GTX-295's.

What are your computing preferences set to. Does it allow Nvidia or just CPU?

This is what I am still getting when I try to get work.

3/8/2012 10:02:04 PM | Milkyway@Home | update requested by user
3/8/2012 10:02:07 PM | Milkyway@Home | Sending scheduler request: Requested by user.

3/8/2012 10:02:08 PM | Milkyway@Home | Scheduler request completed: got 0 new tasks
3/8/2012 10:02:08 PM | Milkyway@Home | No tasks sent
3/8/2012 10:02:08 PM | Milkyway@Home | Tasks for CPU are available, but your preferences are set to not accept them

here is my preferences page.

Resource share 230
Use CPU Enforced by version 6.10+ no
Use AMD (ATI) GPU Enforced by version 6.10+ no
Use NVIDIA GPU Enforced by version 6.10+ yes
Is it OK for MilkyWay@Home and your team (if any) to email you? yes
Should MilkyWay@Home show your computers on its web site? yes
Default computer location ---
Maximum CPU % for graphics
0 ... 100 100
Run only the selected applications (all applications)
If no work for selected applications is available, accept work from other applications? yes
Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy.
default 60.0 (corresponds to 60 fps) 0

I was running BOINC 7.0.3 but upgraded to 7.0.20 to see if that would work Nope it did not.
I have never had any trouble getting GPU work before.

Stealth Eagle,

Looks like you may need to check your preferences at the Milkyway@Home end of the connection as well. Many of the BOINC projects allow settings there to limit what kinds of workunits you will be sent.

I'm having no trouble getting workunits under 7.0.3.

Have you tried?:

Setting "Run only the selected applications MilkyWay@Home: yes
MilkyWay@Home N-Body Simulation: no"

Setting "If no work for selected applications is available, accept work from other applications?" to No

Aborting any nbody tasks in your cache

Suspending DistrRTgen

Increasing your "Minimum work buffer" in BOINC Manager, Tools>Computing preferences>network usage tab

The GT 220 doesn't have double precision, so it doesn't work here. Any of the newer Nvidia-based graphics boards with a Fermi chip should work, EXCEPT most of those intended for laptops instead of desktops.

NVidia outdo AMD, with their inability to do FP64!
I thought the HD 7770 (1/16) was miserable but that was a mid range card. NVidia's new 'Top' card, the GTX680 only offers 1/24th the FP32 performance.
For here, Avoid the GTX680!

Message 53899 - Posted: 3 Apr 2012, 13:46:32 UTC - in response to Message 49566.  

Zy,
I just bought a new EVGA GT 520 after my GT 8500 yoasted itself. The GT 520 has a Compute Capability of 2.1 and my card has 2 GB of memory yet I have never seen any BOINC application use the GPU from the GT 520. I particularly noticed with Milkyway since I have had several dozen Milkyway tasks that require 2 CPU/GPU units to process. But every time one executes, it uses my two CPU's but never uses the GPU to process the application. I had no problem with using the GT 8500 GPU so I am really puzzled why it won't use the GPU on the GT 520. After all it has plenty of memory with 2 GB and the speed of the GPU seems to be fast enough at 810 MHZ. The GPU can be overclocked with EVGA's supplied software.
So is this card supported for GPU use with BOINC or do I have to move to a higher card? EVGA does offer a swap facility so I can get full purchase credit if I do have to move up to a more powerfull card but I only have 90 days to do so.

BOINC should support it, but some of the BOINC GPU projects don't. You might try each of the projects I run on my G105M, for at least long enough to check if your BOINC settings allow the use of it:

Einstein@Home
PrimeGrid
Collatz Conjecture

Note - both POEM@Home and World Computing Grid have announced that a GPU application related to medical research is planned soon, but neither appears to have it ready for Nvidia-based boards yet.

Also, you may want to check the first page or two of the BOINC log file, looking for the line that shows that BOINC was able to detect that board.

Note that some of the BOINC projects that can use Nvidia GPUs ask their users to avoid use of the 195.* and 196.* series drivers, so also check the BOINC log file for what driver version that card has.

You may also want to check the rating of your power supply, to make sure it is adequate for any replacement board you choose.

When I checked the specs for the GT500 series of boards, I found that the two at the low end don't mention whether they have Fermi chips or not, but most of the higher ones say they have a Fermi chip. I believe that the GT 520 is one of those that didn't say.

Message 54070 - Posted: 19 Apr 2012, 15:18:07 UTC - in response to Message 53906.  

After a lot of 'Trojan and viral', infections, I had to clean out 3 hosts,
2 of them now have work.
The I7-2600 + 2x EAH5870 GPU's now run Milkyway and do very well, I think.
With the I7-2600 free to load and unload the GPU's, they do a WU in 60 to 65 seconds, which I think is good.
I run WINDOWS 7 64bit (OEM) Pro and BOINC 7.0.25, even with only the GPU's used, the system gets very hot! And need additional cooling, using cold outside air.
I started on wednesday, very early, about 01:00, but found the system shutted down, this morning. Thermal shut-down!
And I noticed the 4 cores, with HT turned on, have a ~20% average load.
The DDR 3 1600MHz, also gets hot. Also use a C(ompact)F(lash), as
Ready-Boost-Cache, making the HDD's, 5TByte total, faster on reading and writing.
It uses (a staggering) 550Watt per hour, so that will be 'My Donation", as
I'm (very) low on income.............

Milkyway, Einstein, SETI, bĂȘta too, and GPUgrid are now my main projects.
(Still have to install optimized app.'s for SETI MB and Astropulse.).

Fred J. Verster,

Have you tried the Tthrottle add-on for BOINC? I have found it good at slowing down CPU workunits on my laptop to control heating, even though it does not seem to have much ability to slow down GPU workunits.

It's also able to display the current temperature for each CPU core that has a suitable device for measuring the temperature, and also each GPU that has such a device (most of the recent CPUs and GPUs have them).

http://efmer.eu/boinc/

http://www.efmer.eu/boinc/tthrottle_manual.html

Likely to be suitable only for Windows versions of BOINC, though.

My desktops use it only for displaying the temperatures, though - they came with adequate cooling.

My laptop needs a little more to perform well, though: Tell it to use only two of the following items - its two CPU cores and its GPU.

Note that it it takes extra effort to tell it how to control non-BOINC programs that often try to run at night, such as some antivirus programs.

Some computers come with programs that can speed up their fans, but such programs often make them noisy as well.

Watch what can block any of the vents on your computers - one of my previous computers gave a scorched smell and became unbootable soon after the side with a vent for letting air in was slid against the side of the cabinet holding it.

Note that BOINC seems to have problems with adjusting its requests for workunits to handle such slowdowns properly, so you may need to limit its queue of workunits waiting for execution so that few workunits will be found in the queue at any one time.

I would like to get back into milkyway@home but at the moment I could only do it using a low profile gpu.
I am aware of a few options with nvidia stock but I would much rather stick with radeon's for this project.
Is anyone here using a milkyway compatible ATI low profile gpu.

Nope, there are no low profile double precision AMD cards out there.

I find it amazing that AMD have not got any products in this sector, oh well, thanks anyway arkayn.

I'll have to figure out which nvidia low profile gpu's have the best output.

Don't the new 7750s and 7770s support DP float? Is I read it the dp-float-performance is only 1/16th of sp-float, but I think that's not too unusual for low-profile cards.
Anyway, the "Cape Verde" chips should support 64 bit fp and come with very little power consumption.
Happy crunching!

They do support DP, but they are full size cards.

Not quite, low profile is for smaller cases usually dedicated to media PC's
Normal profile cards that fit in most cases.

Low Profile cards.


The VGA port can be removed to make it fit into this type of case.
