81) Message boards : News : Temporary slowdown (Message 154) Posted 8 Jan 2019 by Jim1348 Post: Thanks for the update. That is what we need to know to prepare. The last batch ran quite well; a few errors, but I am sure you can take care of them.
82) Message boards : Number crunching : Short time limits require short buffer (Message 146) Posted 20 Dec 2018 by Jim1348 Post: that would be okay, if the admins would communicate this. Yes, I agree. We really don't know what is going on, and how our machines are being used. They need to tell us.
83) Message boards : Number crunching : Short time limits require short buffer (Message 144) Posted 19 Dec 2018 by Jim1348 Post: I keep the default buffer of 0.1 + 0.5 days, and have no problem with a 24 hour limit. It is entirely possible that some of this work is for student projects, and they may need the faster turnaround. Not all projects are for all crunchers.
84) Message boards : Number crunching : Huge number of downloads (Message 141) Posted 17 Dec 2018 by Jim1348 Post: You are stating the problem, not the solution. They need to implement more realistic estimates.
85) Message boards : Number crunching : Quite a few of my tasks end with 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED (Message 137) Posted 17 Dec 2018 by Jim1348 Post: one work unit now is at the 9 hour point; most finish in about 2 to 4 hours. I ended it at the 11 hour point, as the CPU% continued to drop. Clearly, it was not doing any work.
86) Message boards : Number crunching : Quite a few of my tasks end with 197 (0x000000C5) EXIT_TIME_LIMIT_EXCEEDED (Message 136) Posted 17 Dec 2018 by Jim1348 Post: I have not seen that error message, but I have had several that apparently got stuck. I am running on an i7-3770 (Ubuntu 16.04), and one work unit now is at the 9 hour point; most finish in about 2 to 4 hours. Also, the Progress % is shown at 100% on BoincTasks, and the CPU% is now decreasing. https://boinc.nanohub.org/nanoHUB_at_home/result.php?resultid=441643 I will let it go for a few more hours, and then get rid of it. It may be the same thing you see, but without the error message.
87) Message boards : News : Welcome alpha testers (Message 134) Posted 15 Dec 2018 by Jim1348 Post: I did not see any multi-threaded work units. They each ran on a single core of my i7-3770 (Ubuntu 16.04, VBox 5.1.38). But I did see high write-rates; about 190 GB/day (total for all the cores), though I did not notice which ones. I will check it again when I get more.
88) Message boards : Number crunching : Short time limits require short buffer (Message 119) Posted 12 Dec 2018 by Jim1348 Post: Thru, but then they should make somekind of statement of that on the frontpage. I am all in favor of more communications when they have peculiar requirements. (They are still in the learning phase.) At the moment, I have a couple of WUs that appear to be stuck, or maybe it is just a problem with the progress report. That will be interesting.
89) Message boards : Number crunching : Short time limits require short buffer (Message 116) Posted 12 Dec 2018 by Jim1348 Post: A longer deadline is the only option that will work for everybody. Except perhaps the researchers. They may need a shorter time limit.
90) Message boards : Number crunching : Short time limits require short buffer (Message 113) Posted 12 Dec 2018 by Jim1348 Post: The present work units have an 8-hour time limit. So to ensure that I don't receive more work units than that, I am shortening the buffer to 0.1 + 0.15 days = 6 hours max. Maybe nanoHUB has a built-in limit? I have not seen it yet.
91) Message boards : Number crunching : Huge number of downloads (Message 112) Posted 12 Dec 2018 by Jim1348 Post: My next download picked up 16 work units. That is much more reasonable, and I will have no problem finishing them in time.
92) Message boards : Number crunching : Huge number of downloads (Message 110) Posted 12 Dec 2018 by Jim1348 Post: When it rains, it pours. After getting nothing for months, I now have so many downloads I can not count them. And they all have a time limit of later today. This will not work. I will abort them, and hope that the time estimates are better next time. I know, it is a learning curve.
93) Message boards : Number crunching : BSOD, Stop Code: Video Memory_Management Internal (Message 106) Posted 11 Dec 2018 by Jim1348 Post: It could be an anti-virus problem. Be sure to exclude the BOINC Data folder from the AV. Sometimes you even need to stop the AV entirely. (I use dedicated machines, and avoid AV's like the plague.)
94) Message boards : News : Welcome alpha testers (Message 102) Posted 11 Dec 2018 by Jim1348 Post: If I run this project it seems to write several GB every minute on my ssd. Thanks for the warning. I haven't received any work to even check it. But I use a write-cache (or place the BOINC Data folder on a ramdisk) in that case. For Windows, I use PrimoCache or Primo Ramdisk Pro (Dataram RAMDisk also works). For Linux, you can set up a write cache of any size by just increasing the parameters of the built-in write cache. Of course, you need enough DRAM to do any good; probably 2 GB at least, though I usually do 8 to 12 GB for the cache/ramdisk (beyond what you otherwise need). If anyone needs setup info, I can provide it; even better if/when I get any work to test it out here.
95) Message boards : News : Welcome alpha testers (Message 76) Posted 18 Nov 2018 by Jim1348 Post: All of the applications are marked "vbox64_mt". Do they require VirtualBox? You would think they would say so someplace.
96) Message boards : News : Running again (Message 67) Posted 10 Nov 2018 by Jim1348 Post: I don't think we are causing the problem. I don't get any on BOINC.
97) Message boards : Number crunching : Error in request message: xp.get_tag() failed (Message 63) Posted 9 Nov 2018 by Jim1348 Post: Works for me too.
98) Message boards : Number crunching : Error in request message: xp.get_tag() failed (Message 59) Posted 8 Nov 2018 by Jim1348 Post: If you encounter this error, please post the (UTC) time at which you encountered it. 22:00 hours UTC on 8 November (today). 1924 nanoHUB_at_home 11/8/2018 5:00:53 PM Error in request message: xp.get_tag() failed
99) Message boards : Number crunching : Error in request message: xp.get_tag() failed (Message 54) Posted 7 Nov 2018 by Jim1348 Post: I get "Error in request message: xp.get_tag() failed" also on both a Win7 64-bit machine (i7-4771) and an Ubuntu 16.04 machine (i7-3770) each time I request a work unit.
