I am confused is Jason multibeam x41zb Cuda, supposed to replace the lunatics unified installer as if being faster or better than the lunitics? So I should run this now since lunatics no longer has a download for their versions. This is the first I have heard of multibeam x41zb from Jason. I realize it is a hand install. So this is what crunchers are using now? ____________ | |

I have been running x41z for some time, but that was not public beta. The zb version is newer, and has been released for public beta by Jason. I shall probably cut over to zb myself when I have the time to modify 9 rigs...probably over Christmas vacation in a couple of weeks. ____________ ****** "Ask not, what your kitty can do for you.

I thought it was going to be a tedious task, but it wasn't time consuming. you just have to make sure you change the application markers in the app_info: (e.g for my GTX460 and GTX650 machines this is what changed in my app_info) <file_name>Lunatics_x41zb_win32_cuda42.exe</file_name> <file_name>cudart32_42_9.dll</file_name> <file_name>cufft32_42_9.dll</file_name> and of course make sure you copy and paste the appropriate files from Jason's x41zb folders. a quick find and replace all did the trick for each one ____________ | |

Yes, I have done it many times. Just takes a bit when you have 9 rigs to do. I just download the apps on my daily driver and put them on a thumb drive to transfer the correct app to each one. Some are 64 bit, some are 32 bit, some are Fermi, some are pre-Fermi. So I have to get the right app on each one, and then make sure I do the edits correctly... And then do the same with the new drivers....which also take a bit of time on each one to update. ____________ ****** "Ask not, what your kitty can do for you. Ask what you can do for your kitty."

msattler you can try directly x41zc_Winx64_cuda50 for my Quad GTX 295 cuda 50 is faster then 42 i have installed 310.70 driver too. I can say that with SetiPerformance64 stock work unit the difference is 8sec almost in favor of cuda50 and 310.70 | |

I have been running driver 310.54 for sometime without any issues. I just installed 310.70 and x41zc CUDA 5.0 for my system with a single 680 clocked at ~ 1300 MHz. I am so far seeing processing time ranging from 59 - 331 seconds running 1 task at a time. GPU load is from 94-96%. | |

Has anyone noticed that the Cuda _x41g tasks are processing faster under Nvidia beta driver 310.70 or is it just me? I have even increased my tasks per GPU for both the 1 x GTX660SC @ 2Gb and 1 x GTX460SE @ 1Gb from 2 to 3. Processing went from an average of 19-22 min to 15- 20 min. Temps for the GTX660SC remain below 67c & the GTX460SE below 57c. SAME HERE for beta 310.70 - Just running Seti on Card Running GTX550Ti (Know it's not the best, but was affordable) Will monitor for any problems. ____________ | |

None of my video cards are really great but I have switched to the new drivers and every one of my computers seems to be doing more......take a look at me and my computers. Lunitics installer.....that is what I have at present. (the one no longer publicly available) ____________ | |

I can say that with SetiPerformance64 stock work unit the difference is 8sec almost in favor of cuda50 and 310.70 I'm using x41zc, so far so good on the ol 590 and 306.97 x64 under Win7 Pro x64. ____________ BSG Anthem My Facebook page | |

Could someone post the manual install instructions for someone who is doing a fresh install? I just returned to S@H in the last few weeks and would like to run an optimized client. | |

Hello Jason, I got those .7z packages from the mentioned link: | |

Hello Jason, I got those .7z packages from the mentioned link: Hi, Cuda 5 embeds native Kepler & Kepler 2 class code. I'm not using the added dynamic parallelism & other K2 features yet as such, but the native compiler & libraries benefit the Keplers by some small amount. For the time being there will be some small performance benefit mostly on Kepler class ( e.g. GT 680 ) if you use the Cuda 5.0 build. That's mostly related to the build having embedded Compute capability 3 binaries, and use of Cuda 5's Kepler specific libraries & compiler... IOW natively it'd be a slightly better match for these cards. On similar lines the Cuda 4.2 build will probably remain preferable for Fermi Class cards at least for the time being. That Cuda version dependance with GPU generation could be anywhere from splitting hairs to noticeable, and mostly ties to underlying driver, compiler and library technology changes (that are ongoing). At some point in the future I intend to replace the FFT library used, but for the short to medium term that will be the dominant source of version performance variation under Cuda.

Could someone post the manual install instructions for someone who is doing a fresh install? I just returned to S@H in the last few weeks and would like to run an optimized client. Hi, Being beta/advanced user software at this time, I'd advise waiting for an installer/release/update, especially If you are unfamiliar with the app_info.xml file configuration. I'm not sure when Lunatics will provide one though, if you feel adventurous the anonymous platform mechanism is documented at http://boinc.berkeley.edu/wiki/Anonymous_platform. You would basically need to splice the provided appinfo stub content into app_info.xml, along with entries for any other applications you'd be using (such as CPU apps & Astropulse) Jason ____________ "It is not the strongest of the species that survives, nor the most intelligent that survives.

Jason On the one hand for simplicity I'd say Cuda 4.2 will do fine, but probably in splitting hairs territory with gains in one type offset by marginal reduction in the other. IOW, in total throughput & other characteristics you'd have trouble telling the difference without looking quite deep. On the other hand you could say Cuda 5.0, & associated drivers & libraries, are likely to still mature a bit further, and seem to be quite good under system contention etc already.., so it'll just depend on personal preference & whatever else you might be using the machine for. ____________ "It is not the strongest of the species that survives, nor the most intelligent that survives.

Here is the app_info.xml that I made for running x41zc and the Astropulse GPU application that downloads by default from the Seti project servers if this project and GPU support are enabled. Both apps are running good for me via my GPU. The file does not have any CPU apps in it currently. ____________ | |

Thanks Guys! | |

Thanks Guys! I'm pretty sure, but don't quote me unless it is confirmed, that it is to reserve part of the cpu so that it can do the management on data transfers et. But due to the powers of the GPU's and the relative lower power of the CPU cores these days. I just restrict my CPU processing by one core. e.g. on Quad in BOINC preferences I set "On mltiprocessor systems, use at most 75.00 % of the processors" | |

I do have another question, however. I understand the <count> parameter, currently I have mine set to "0.5" for two processes, but I am a bit unclear as to the <avg_ncpus> and <max_ncpus> parameters. Those numbers are used by the scheduler as a reference of how much CPU is needed by the GPU app but it doesnt limit the CPU usage of the GPU apps. The scheduller adds all the CPU fractions (of the running GPU apps) togheter and the result trimmed to the least integer is the number of cores that will be "reserved" for feeding GPUs... For these calcs it uses the avg_ncpus, Im not sure for what is used the max_ncpus, so I set both to the same value, just in case... This could be used to reserve extra cores dinamycally based on the running apps, for example I have the AP apps set to 0.7 CPU and the MB to 0.25, as I run 3 concurrent WUs, if there is 3 APs running BOINC will leave 2 extra free CPU cores, if there is 3 MB running it wont be "reserving" any extra core, and in the other cases it will reserve 1 or 2 depending on which combination of apps are running... (the APs need more CPU support due to something related with the "high CPU usage" bug in the implementation of newer versions of OpenCL). ____________ | |

...but I am a bit unclear as to the <avg_ncpus> and <max_ncpus> parameters. BOINC uses the avg_ncpus value to decide whether to free CPU cores to support GPU processing or not. If avg_ncpus multiplied by the number of GPU tasks running is 1.0 or more it will start one less CPU task, etc. Obviously the max_ncpus should be equal or greater than avg_ncpus, but it isn't really used so that would just be protection against some future version of BOINC where the logic changes. I imagine you'll be running multiple GPU tasks on your 660 Ti, you might consider setting avg_cpus to 0.5 so whenever there are 2 or more GPU tasks running one CPU core would be freed. But if your cache ever got down to one or less GPU tasks all CPU cores would also be doing tasks. With the current limits, that's a fairly likely scenario if the project has another server problem.
