For one, you are running cuda which is extremely slow. That card should handle SoG - I think. |

Anymore ideas please? |

blcXX_2bit_guppi_........... The "guppis" need about twice as much calculation time for identical crediting as the old ones. According to the server status, there are only these. |

Anymore ideas please? That's it. Run SoG, not CUDA. Make use of the command lines, aggressive settings if it's not a daily use machine, and you will get a lot more work out of those cards. Your GTX 690 runtimes using CUDA 47min Your GTX 690 runtimes using SoG 18min 30 sec (better times possible with command line values) More than double the output. My GTX 750Tis runtimes using SoG 13-14min I've no idea why all the more recent SoG WUs errored out, change in video driver AV programme, or other CPU intensive programme on that system? Given each card has 2 GPU chips, and each SoG GPU requires the support of 1 CPU core/thread, you need every CPU thread that system has to feed the GPUs. Have another CPU hungry programme there & things could get very ugly. And using SoG on your other system's GTX-750Ti would almost double it's output with the right command line values.
