Message boards : Graphics cards (GPUs) : GPUGRID vs SETI@home beta

I started a new thread for this. What applies for GPUGRID should apply for Seti. OK here are some comparisons. On my one system, that is and under WindowsXP All times approx. These are run with 6.4.5 GPUGRID runs 59000s/16.5h elapsed time with 48000s/13.33h cpu time, which is about 40% cpu usage, when observed with windows task manager. SETI@home beta runs 26 minutes wall clock time and only uses 7min cpu time. It was hard to rate the cpu usage. It runs near full 44-50% for the first 30 seconds, then it drops to 3-12%, average 10%. Later in the task though it runs more like 12-22%. I saw spikes, both ways with the cpu anywhere from 2-23%. Mostly though you could say the average was 10%. A lot less than GPUGRID. I do not know how credits compare yet. ____________ Alpha Tester ~~ BOINCin since 10-Apr-2004 (2.28) ~~~ Join team USA ![]() | |

On my System is very more CPU usage @GPU-Grid | |

I got a couple returned results. | |

I ran some over there too & had it figured about 420 Per Hour where I get about 600 Per Hour here on the same Box with a Overclocked GTX 260 (216 Version) ... | |

I got a couple returned results. I'm running both, but more slanted towards gpugrid because its more stable, offers better credits, the science is better, and the user base are tech savvy. Based on the current deadlines I guess I'll be crunching more gpugrids than seti: 1 month seti vs 4 days gpugrid. | |

A thing that I like from SETI is that you can have a lot of units in cache (which seems to contrdict the statement that it is BOINC, not GPUGRID that limit WU to 1 by each CPU) | |

(which seems to contrdict the statement that it is BOINC, not GPUGRID that limit WU to 1 by each CPU) GPU-Grid limits the amount of concurrent WUs to 1 per CPU because BOINC oes not yet allow one to tie the amount of WUs to the number of GPUs. GPU-Grid needs this limitation because they need results back fast, whereas for SETI only the long term throughput is important. MrS ____________ Scanning for our furry friends since Jan 2002 | |
