OPN1 tasks on my computer are completed after about 1:45 hrs while OPNG are completed in less than 2 minutes.
----------------------------------------From the scientific value, is there a difference between the OPN1 and OPNG tasks? Do they provide the same or comparable results? [Edit 1 times, last edit by GolfSierra at Oct 14, 2022 8:25:09 PM] |

Do they provide the same or comparable results? Hi GolfSierra, the basic difference is OPN1 uses CPU and OPN1-GPU (OPNG) uses GPU for its results. As described in this article , GPU calculations use an updated docking algorithm and thus provide more accurate results, and also some speedup in average. Also, since GPU has many more cores compared to CPU it does run faster. [Edit 1 times, last edit by Cyclops at Oct 14, 2022 10:07:49 PM] |

My Nvidia Titan X running at 1.5GHz runs a task in less than 2 minutes. (I run five tasks concurrently in a little over  [Edit 5 times, last edit by Vester at Oct 15, 2022 12:35:48 AM] |

Similar difference here, though on much older hardware.
----------------------------------------However, there's no OPNG tasks since at last a week and i wonder, if there are any plans posted anywhere, announcing future schedule for OPNG WUs. [Edit 1 times, last edit by jayrope at Dec 5, 2022 9:41:00 PM] |

I've got an old GTX-750 GPU in a 20-thread i9-10850k machine. OPNG easily outperforms all 20 of the CPU threads combined, based on points earned. The difference would be really huge on a bog standard 4-core machine. Bring 'em on!

Will there be OPNG work units again?
