1) Message boards : Number crunching : new version of BOINC + CUDA support (Message 58585) Posted 6 Jan 2009 by computerguy09 Post: SETI@HOME is another. You need the latest BOINC and the latest NVidia drivers. The early versions of the 8800 GTX/GTS do not work with cuda. Be warned though, after reading the messages over on the SETI board it seems to have a lot of bugs. Some people have also had problems with overheating. I'll wait til they come out with version 2.0 and work out the bugs. Thanks for Your info. I'm looking forward to donate to life sciences. My new steel has 2 x NVIDIA GTX 280 cards running on Phenom host with total 1,8 TFLOPS. It's important to remember that CUDA is an API that an application can use. How well it is used, and how "buggy" the code is dependent on the programmer, not CUDA. The SETI CUDA application seems to be having major teething pains. The GPUGRID CUDA app is a little farther down that path, and it is running much more reliably, when work is available on that project. It's my understanding that several other projects are considering supplying CUDA-based apps. Mark
2) Message boards : Number crunching : WU Problem Linux (Message 44771) Posted 7 Aug 2007 by computerguy09 Post: I was having this problem on a Linux Mepis box. I updated to the latest version of BOINC and the problem seems to be reduced or perhaps even fixed. I haven't caught it sleeping on the job in a while at least. I think I'll check my memory allocation though, I have seen that "Waiting for memory" error even though the machines should have plenty of meemory for the task. I'm running BOINC version 5.8.16 for i686. I haven't upgraded to 5.10.* because they are still working out serious bugs last time I checked. I saw this problem on my Ubuntu box (dual core AMD) while running 5.8.x, and early versions of 5.10.x. I've been running 5.10.8 for over 2 weeks now with no "hanging" processes. Used to have to restart BOINC every day or so on this (and other) boxes, but haven't seen it since going to 5.10.8 of BOINC. Mark
