1) Message boards : News : More xoroshigo2 configs (Message 1269) Posted 21 May 2025 by Keith Myers Post: Thanks for the heads up. Hope the server configuration for outstanding, pending results you spoke of works this time.
2) Message boards : Number crunching : GPU calculation error (Message 1264) Posted 16 May 2025 by Keith Myers Post: Could be, the Maxwell 2 cards are supposed to be supported, but the app has to make some drastic changes in running to accommodate those cards. Your card might be an Maxwell type 1 card in fact and why it fails. Might PM boysanic specifically and ask him what the error indicates. He is the admin and main tester for the app developers.
3) Message boards : Number crunching : Stronghold Bookfinder - High Memory Usage (Message 1259) Posted 6 May 2025 by Keith Myers Post: My recommendation for beta apps is to also produce very small sized runs first to see how they fare among the crunching populace. No point in generating a ton of faulty work which wastes bandwidth and is going to have to be reissued anyway. When the return rate is above 90% successful, then you can go for full deployment and remove beta status.
4) Message boards : Number crunching : Stronghold Bookfinder - High Memory Usage (Message 1255) Posted 6 May 2025 by Keith Myers Post: Did you just run the task locally on a host? Or did you run it through an actual production Boinc environment? I never saw a beta release for the app where you set up a very limited run of tasks sent to a few hosts before sending it into production. I just saw the app in the applications list with no tasks available and then overnight, there were thousands of the tasks generated and ready to send and all my hosts were fully loaded with these faulty tasks. If there was a beta period, it was staggeringly short. We appreciate your work running the site. Didn't know you were a one-man show though. I had assumed from your Discord server there were more of you, admins and developers.
5) Message boards : Number crunching : Stronghold Bookfinder - High Memory Usage (Message 1252) Posted 5 May 2025 by Keith Myers Post: Same here. All Stronghold Bookfinder tasks are erroring out with file missing errors. 95 failures so far. No successful attempts.
6) Message boards : Number crunching : Very slow downloads All tasks in long backoffs (Message 1245) Posted 2 May 2025 by Keith Myers Post: Very slow downloads All tasks in long backoffs for the last couple of hours
7) Message boards : News : New Badges (Message 1197) Posted 21 Apr 2025 by Keith Myers Post: Nice!
8) Message boards : Number crunching : 1.20 Find seeds with zero villages within a radius v1.08 failing on Quadro M5000 (Message 1186) Posted 20 Apr 2025 by Keith Myers Post: The error message says it detects specifically a case for the Maxwell class gpu and makes some changes in the app code for it. But it does not handle the card correctly after that and produces instant errors. You still need to check with the developer boysanic and see if the app really CAN handle the Maxwell card and if it supposedly can, need to report to him the app is busted on your host.
9) Message boards : Number crunching : New CUDA app?? 1.21.4 Pale Garden Panorama Cracker (Message 1175) Posted 19 Apr 2025 by Keith Myers Post: New CUDA app. What's the story here?
10) Message boards : News : Xoroshigo2 v1.05 - Runtime fix (Message 1168) Posted 19 Apr 2025 by Keith Myers Post: @boysanic didn't indicate that any task returned after deadline would get credit AFAIK. So no point in continuing to run the work after deadline in my opinion.
11) Message boards : Number crunching : 1.20 Find seeds with zero villages within a radius v1.08 failing on Quadro M5000 (Message 1163) Posted 18 Apr 2025 by Keith Myers Post: I believe the card is too old an architecture to run on the app. Check with boysanic the developer.
12) Message boards : News : Xoroshigo2 v1.04 - New plan classes (Message 1155) Posted 16 Apr 2025 by Keith Myers Post: Credit was already quite high for the given run time. I wouldn't suggest going higher. You're fixing the issue. If run times return to a more normal 1-2 hours the deadline is acceptable too. Doesn't matter, the runtimes are 10-20x and more longer...the credits need to be adjusted to make up for not only the extended runtimes, but also the fact that even before this batch a lot of tasks from earlier this month went Invalid. That is quite a bit of resources wasted with no reward. +1 I agree, especially for the already returned ones that were in fact valid and only invalidated because the tasks were cancelled by bad admin configurations.
13) Message boards : Number crunching : Xoroshigo2 v1.1 Issues Megathread (Message 1148) Posted 15 Apr 2025 by Keith Myers Post: The News sub-topic has the developer's answer on what happened with these tasks and the current investigation into their intended fix. https://minecraftathome.com/minecrafthome/forum_thread.php?id=212&postid=1145
14) Message boards : News : Xoroshigo2 v1.04 - New plan classes (Message 1147) Posted 15 Apr 2025 by Keith Myers Post: If the tasks get fixed back to the intended fixed runtimes, there will be no need to update the fixed credit system. But I agree we are getting shorted on credit for the current long running tasks for the amount of calculations we are inputting into the effort. Maybe we can be credited accordingly for these temporary long running tasks in the meantime.
15) Message boards : News : Xoroshigo2 v1.04 - New plan classes (Message 1144) Posted 15 Apr 2025 by Keith Myers Post: Thanks for the progress update. Hope it gets resolved soonest.
16) Message boards : News : Xoroshigo2 v1.04 - New plan classes (Message 1141) Posted 14 Apr 2025 by Keith Myers Post: Is this new app making WUs run 10x longer? Don't know. We never saw this on the earlier apps. Developer said he tested the app for the first 50 confguration files and saw no issues. But the latest configuration files are screwing the app up or something.
17) Message boards : Number crunching : Xoroshigo2 v1.1 Issues Megathread (Message 1140) Posted 14 Apr 2025 by Keith Myers Post: I asked why the change in completion times on the project's Discord server from the developer. This is his reply. "The summary is that each config file tells the app to search with different sets of constraints. When developing the app I made sure to track the total number of loop iterations to ensure each version ran for the same amount of time, no matter how large of a space it was asked to search. My method seemed to work perfectly for the first 50 or so config files we sent out, but there seems to be some kind of pathological case that's screwing it up." No response after that so don't know whether they are working on a fix for this in a new app, or whether they are going to adjust the deadline dates or what?
18) Message boards : Number crunching : Xoroshigo2 v1.1 Issues Megathread (Message 1133) Posted 14 Apr 2025 by Keith Myers Post: Several others already past 12 hours of computation time and most not yet to 50% completion. The Epyc cpus 7713 and 7B13 can only manage around 2Ghz so those ones are in danger of not completing in 72 hours. An example on a Ryzen 9950X cpu running north of 5.2 Ghz.

19) Message boards : Number crunching : Xoroshigo2 v1.1 Issues Megathread (Message 1132) Posted 14 Apr 2025 by Keith Myers Post: I too am seeing much, much longer completion time estimates and progress percentages than all the prior tasks. The slower cpus are not going to be able to complete tasks within the current deadlines. Also, is the credit awarded going to be commensurate with the longer compute times needed. We're talking a 10X factor here at least compared to the credit awarded for the prior series of tasks that took 1 hour on modern cpus.
20) Message boards : News : Xoroshigo2 v1.04 - New plan classes (Message 1127) Posted 13 Apr 2025 by Keith Myers Post: Thanks for the new apps. Should reduce the error rate from older hosts. Running some lin-modern now already with no issues.
