From Ralph@home: Starting this week, we will begin testing RoseTTAFold All-Atom, our state-of-the-art application designed to predict the structures of proteins in complex with ligands such as DNA and other biological molecules. It also models post-translational modifications. We are initially targeting only Windows machines with or without Nvidia GPUs for this test I would prefer and opencl/rocm/oneApi app that run over all platforms (i'm Amd boy), but it's, despite all, an historical moment for this project!! |

Looks like a new CPU application, with, maybe, possibly, a GPU application at some stage (maybe...). Grant Darwin NT |

The first batch of this app on Ralph: all errors!! Waiting for a better app |

Looking at the error messages, the Tasks sent out were faulty. A quick search gives this result the reason you typically see the “End-of-central-directory signature not found” error when working with a zip file is because the file is either corrupt, the file download is incomplete, or it’s a multi-part archive file and the other components are not found, or the zip file is not actually a zip archive file. The most probable reason for most users to encounter this error when trying to unzip a zip archive though is that the zip file download is either incomplete, or the zip archive is corrupt.With everyone getting the same error, i can't see it being a download corruption issue (unless there is some really odd configuration issue with the download server). I'm guessing it was archived incorrectly- wrong flags set or there are files within that archive that are missing from the archive that should be there. Grant Darwin NT |

After YEARS and YEARS of waiting for a gpu app, i think we have to be satisfied (a little bit)If they had released a GPU maybe, maybe. So far, it's only a CPU application. Grant Darwin NT |

If they had released a GPU maybe, maybe. In Italy we say "Se son rose, fioriranno" (letteraly "if they're roses they'll bloom", something like "time will tell"). |

After some days of down, the servers of Ralph restarted and are releasing some wus. All errors, as a week ago :-( |

The new app (0.02) has a lot of problems.... |

The new app (0.02) has a lot of problems....But at least they are running now. They just need to fix up the CPU usage & the lack of any checkpointing, and the inability to suspend them, and the fact that they never seem to complete... Grant Darwin NT |

Seems that the hw request for this app is an Nvidia gpu with, at least, 6gb of ram... |

Seems that the hw request for this app is an Nvidia gpu with, at least, 6gb of ram...Actually, with the latest version, it's (effectively) an 8GB minimum (i can't think of any cards with more than 6GB and less than 8GB). With the previous version my 6GB card was able to process work with no issues. With the new version, it is 1MB short of the minimum needed to process work. 1MB 6144 MB is the minimum, i've got 6143 MB on the GPU in this system. 1MB! Grant Darwin NT |

Not every R@H volunteer has a gpu with 8gb of memory... Meantime, i continue to run Folding@home |

I hope that, after the debug of problems, they will start to think to "optimize" the code.As i mentioned, it was running in 6GB of VRAM before. So hopefully they can bring it back under 6GB again. Grant Darwin NT |

With the previous version my 6GB card was able to process work with no issues. With the new version, it is 1MB short of the minimum needed to process work. Writing this in complete ignorance, so ignore if not relevant. Is it like the situation we had with Raspberry Pi devices that time(?) when an amount of RAM needed was hard-coded in but free RAM was fractionally below, so only 4Gb devices could run tasks, even though actual RAM called was way less? Similarly now 6144Mb VRAM hard-coded, but only 6143Mb free on those cards? Or doesn't it work that way with VRAM? Disappointing if so. Not so relevant for me as I think I've gone over the top having 2Gb & 4Gb cards and I doubt that will change anytime soon. Or ever ![]() ![]() |

Is it like the situation we had with Raspberry Pi devices that time(?) when an amount of RAM needed was hard-coded in but free RAM was fractionally below, so only 4Gb devices could run tasks, even though actual RAM called was way less?At this stage we don't know. The previous version was able to run on cards with 6GB of VRAM without issue. Updated version came out and with it the message about the 6144 MB minimum if you had less than that. But we don't know if the new version can't run on 6GB of VRAM, or if the minimum they've set is just that little bit higher than it needs to be. To my way of thinking, if 8GB was the minimum amount then you'd set it that (or even 7.9GB), but to pick a value as specific as 6144MB? (to me that would be 6.2GB, or 6.1GB if it needed just that little bit more than 6GB). It's just an odd value to use. And from an installed base perspective, the vast majority would still be 4GB or so, but ruling out even those with 6GB would take another pretty big chunk out of the available compute resources. It wasn't until the RTX 20 series that all models of card (including the bottom end models) had more than 4GB of RAM. Grant Darwin NT |
