2) Message boards : Number crunching : AMD GPU Computation errors (Message 59577) Posted 11 Aug 2013 by skgiven Post: Tried the 13.1 driver, the 12.8 driver and the 13.8 beta driver. No success. Failures ranged from the WU's reaching 100% and then saying error, to Boinc reporting the GPU but MW saying no ATI GPU, and the system recovering itself, eventually! Also tried several versions of Boinc (avoid). With 13.4 and 13.8 Albert works, Einstein works and POEM works.

4) Message boards : Number crunching : Cant select or deselect an (mt) app, and runtime estimate is 1 second (Message 59256) Posted 6 Jul 2013 by skgiven Post: OK but you could also separate the N-Body Simulations into mt and non-mt runs with different selectable queues, so ordinary crunchers can easily configure what they crunch. The other alternative is running a second instance of Boinc, either in the same OS (different directory...) or in a Linux VM, with limited cores and no GPU - but again, not for the novice. As for trying to fool the scheduler, its already bamboozled. The devs need to respect that people who spend several $hundred on a GPU want to use it, and don't want it sitting idle just so an additional CPU thread/core gets occupied, especially when its running the same type of WU, but 100times slower. This even happens when non-mt apps are unnecessarily prioritized (mostly dual GPU setups). Maybe the runtime estimator isn't working - after 30 mt runs it should be more than 1s. It should even adjust for queued WU's on completion of runs. 1s is probably a default because an estimate isn't being set. This won't be helping the work buffer or scheduler.

'NVIDIA's GeForce GTX Titan, Part 1: Titan For Gaming, Titan For Compute' by Ryan Smyth, anandtech.com I have tested Titan last day on milkyway and it works ok. When doubleprecision is enabled it can run 7 tasks in parallel (~97% GPU, 80% of TDP=200W) and can produce cca 300k credits per day. Have you tried more than 7 tasks in parallel? The Geforce GTX Titan has a peak performance of 4500 Gflop per second SP and 1/3 of the computation units run in DP mode so the DP peak performance should be 1500Gflops. It has 2688 Streamprocessors 1/3 are then 896 for DP. As the top dp frequencies are lower than the top sp frequencies the maximum performance is slightly less than 1/3rd - it's 1.3TFLOPS.

Went back to Boinc 6.10.60 and tried several more. Basically I got nowhere, and was going round in circles. About 30 reboots is my limit. I think it's fair to say that ATI/AMD simply don't support a 2003 x64 server. It worked fine on XP x86, but on 2003 the drivers don't seem to report to Boinc correctly. I can get an all clear on Device Manager and GPUZ reports the GPU correctly, but Boinc say's no. Perhaps the drivers did not register correctly in some way. I've spent too much time on this so I'm giving up. Might find another host at some stage, but for now I'm out of here.

This thing uses about 40% CPU just to open Task Manager! When minimized to the tray it's still using around 10 or 20%. Clean XP install, and nothing else other than FF on the system (not open at the time). No CPU tasks running on that rig either - probably not worth the bother. Point being, CPU usage is very much dependent on the CPU. XP tends to have about a 3% overhead. Not sure about Vista and W7 but I would expect them to be at least 3%. As for the various Linux flavors, it can vary quite a bit. PS. GPU utilization is 98%, except for the few seconds it takes to load a new task.

These stripped down 40nm cards use to be good entry level cards elsewhere, being efficient for single precision jobs, but lacking DP they were never any use here; hence they are not on Matt's list of compatible cards.
