Message boards : Number crunching : GERARD_A2AR Low GPU Utilization

I'm noticing the current A2AR tasks have a low GPU utilization. My 980Ti is crunching one currently at 44% and has therefore downclocked to its base clock speed. My 750Ti is also reporting lower than usual GPU utilization. Has anyone else noticed this or should I start investigating for problems with my machine? | |

See the following threads: "low GPU utilization with recent Gerard CXCL12?" "About the GERARD_A2AR batch" "GPU not fully utilized +Solution." | |

Has anyone else noticed this or should I start investigating for problems with my machine?Now that I got home I see that the workunits from the batch called "GERARD_A2AR_NUL" are those which are extremely slow. I had to suspend all CPU tasks to get the GPU usage up to 42~48%. I have no idea how to increase the GPU usage any further. (besides running two simultaneously on the same GPU) | |

No CPU tasks running on this machine. I've suspended GPUGrid on the 750Ti and am now running 2x on the 980Ti. I guess I'll keep it like this until we get this sorted out. | |

I have a refinement to make regarding the batch name: the "GERARD_A2AR_NUL" workunits were fine. (this is a previous batch). | |
