Posted 19 Apr 2021 by Bryn Mawr Found a bad host: http://gene.disi.unitn.it/test/show_host_detail.php?hostid=25653 Good spot, that’s as bad as they come. |

I keep a very small cache and all I can say is that since the announcement of this challenge I’ve been getting very few WUs to process and even fewer of the WUs I have processed are moving out of pending - their counterparts must still be in someone’s cache waiting to run. |

FMA application for windows_x86_64
(Message 2193)
Posted 3 Feb 2021 by Bryn Mawr The server software is supposed to try different apps to see which one is faster and more reliable. It needs at least N (don't know exactly this number, could be 10 or 20) successfully validated results for each app before it can get an APR (Average Processing Rate), this was the DCF some time ago. You can see the APR numbers for each app when you look at your computer details under your account. Its supposed to pick the fastest app and occasionally send one of the others to see how they go. (documentation about this feature is not so easy to find...) Interesting and it does show that it works, the machine I updated the other week was almost exclusively fma (r5 2600) and has now swapped to almost exclusively avx (r7 3700x). The odd thing is that my old old machine that started as an FX8370 then inherited the r5 2600 shows it was getting sse2 ? |

(Message 2185)
Posted 1 Feb 2021 by Bryn Mawr In Linux, my 3900X, 3950X and Epyc 7402P settled on FMA exclusively as fastest app. Takes about two weeks trying out AVX, SSE2 and FMA before declaring a winner. My 3600 is fma whereas my 3700x is avx so I just leave them to it :-) |

Posted 30 Dec 2020 by Bryn Mawr Could you be so kind and have a look at my system 65300, please? Almost certainly because the work generator cannot keep up with the demand. As I recall, flat out it can generate a few thousand work units per day. At 24/7 your 1,024 threads would process around 8,000 work units. |

Posted 30 Dec 2020 by Bryn Mawr Wow, a wonder happened. The Athlon got now 7 additional WUs (for the next 20 days...). Then you need to examine your default profile very closely because it is showing non-standard behaviour |

Compiling for AVX-512
(Message 2088)
Posted 18 Nov 2020 by Bryn Mawr Oh. I thought the WU needed to match its program since all WUs say what instruction set they're for. Diagnostic for troubleshooting when things go wrong. |

Compiling for AVX-512
(Message 2082)
Posted 18 Nov 2020 by Bryn Mawr FMA against AVX only provided a very small speed gain, that's one of the reasons I do not distribute FMA for Windows... Not convinced by this statement. Almost all my WUs are fma and if I look at the wingmen the very often receive avx or sse2 equivalents - see Workunit 25706025 or 25705750 as examples. |

Server Status - No Work Available
(Message 2025)
Posted 21 Oct 2020 by Bryn Mawr Wasting in the meaning of computing power going somehwere else (or nowhere) instead of being crunching TN-Grid because there are no Wus. No project can guarantee to have WUs all day, every day, year in year out. I run four projects side by side for exactly this reason, recently three of those projects were out of work at the same time - so be it, I was still crunching with no wasted cycles. TN-Grid is a small project with limited resources, expect best endeavours rather than perfection. |

Waiting for Validation
(Message 2005)
Posted 13 Oct 2020 by Bryn Mawr Looking at the server status page shows that there are zero WUs waiting for validation It could be either way, counting pairs or counting each WU, I was hoping it was pairs which would make sense of the data available. |

Posted 12 Oct 2020 by Bryn Mawr Yes, this project requires 2 results per workunit for validation. Thanks for the confirmation. |

Waiting for Validation
(Message 2001)
Posted 12 Oct 2020 by Bryn Mawr I have noticed a massive drop in throughput on my two main computers over the past day and it turn out to be because everything I’ve processed over the past two days is completed, waiting for validation. Looking at the server status page shows that there are zero WUs waiting for validation. Can I assume that my WUs are waiting for a wingman to complete processing before both are passed to the validator? |

Lost Credit ?
(Message 1878)
Posted 2 Jul 2020 by Bryn Mawr Hi everyone. For a long time I stoped crunching and dont remember what my contribution might have been for this project. According to my account data I am a member since 26 Apr 2020 and have no credit. But I am inclinded to believe that I have been a member since before. BAM and Free-DC sites show no credit for me in this project, however, and this is what has lead me to write this post, in Free-DC I have the indication that I have achieved a milestone of 100.000 credits in 10-JAN-2015 in TN-Grid (see here https://stats.free-dc.org/stats.php?page=userbycpid&cpid=863520b4459fdd4ae4ec9f00eed5bf19). Are you certain that you have “rejoined†using the same e-main / username? It sounds as though you are now on a different account. |

Resource Share Problem
(Message 1867)
Posted 25 Jun 2020 by Bryn Mawr OK, I’m still confused but the problem has resolved itself overnight with the resource share being downloaded from TN-Grid default profile. More confusion, the resource share has changed again, this time taking the value from the BAM host within project level. It would appear that sync with account manager does not update this value but the 6 hourly refresh does. |

Resource Share Problem
(Message 1866)
Posted 25 Jun 2020 by Bryn Mawr OK, I’m still confused but the problem has resolved itself overnight with the resource share bein downloaded from TN-Grid default profile. Why the delay I don’t know, it now updates immediately if I change it in TN-Grid and do update which it wasn’t yesterday. Many thanks for the helpful suggestions made. |
