1) Message boards : BOINC Manager : Boinc 100% disk activity, locks up (Message 103399) Posted 3 Mar 2021 by tbzep Post: Edit: actually 3 units running, 2 on the single core and 1 on the GPU. Ah. You hadn't mentioned a GPU. That brings O2MDF and FGRPB1G into play as well, with a wider range of dates. My understanding is that for the tasks using the large data files - the Gravity Wave tasks - the first action is to read and unpack the raw data. Possibly, the portions related to the parameters of the current task have to be extracted. But only after the data pre-processing is complete, can the mathematical processing begin. Only the Einstein team would be able to guide you through all that. Thanks, Richard and everyone. I've posted the info on the Einstein page to see what they say. I may just have to stop running Einstein on this computer or keep running it on a single core. Dr. Who Fan, have you often dreamed of using the Tardis to go back in time to make sure Alou caught that foul ball? :)
2) Message boards : BOINC Manager : Boinc 100% disk activity, locks up (Message 103397) Posted 3 Mar 2021 by tbzep Post: Understood, and you may be on to something. I was just pointing out that I've run Einstein a long time and see the different work unit names all the time. I didn't think it was the problem since it runs fine for over 4 minutes before going nuts. However, I just started it using a single core (two work units) and closely watched the memory and disk usage. At about 4.5 minutes the memory usage doubled, but well within the 8gb limit. The disk stayed at zero. It does seem to be a page swapping issue, but I don't understand why it runs fine for more than four minutes and then doubles the memory usage. Edit: actually 3 units running, 2 on the single core and 1 on the GPU.

Their Gravity Wave search, in particular, relies on having something like 48 downloaded data files, some 150MB - 200MB of raw data, present while the task is running. I don't have figures for the effect this has on memory usage by the application, but I suspect it can't be small. I ran a split of Seti and Einstein for a year or two before Seti shut down. I've been running Einstein on this computer ever since. This issue started week before last. I've always run all four cores and GPU with this computer and allowed 100% CPU and memory use when the computer isn't in use. Suspend is set at 25%. A shake of the mouse has always suspended it within a second or two. With it set to "run always", I have always been able to browse, and do minor stuff with minor lagging. Unless Einstein work units have changed in the last couple of weeks, it shouldn't be an issue. However, I did purge all work units and started new ones last week to see if there was a bad one causing havoc.
4) Message boards : BOINC Manager : Boinc 100% disk activity, locks up (Message 103391) Posted 3 Mar 2021 by tbzep Post: Yes, I have permission to run it. I started running Seti@Home from work in 2001. I noticed task manager lagged behind events that were happening so I put Rainmeter on the desktop. I also timed the events. At approximately 4:20 after starting computations with 3 of 4 cores (and GPU), I saw hard disk and memory both max out. Taskmanager was locking up before I saw changes in memory. I excluded Boinc folders from AVG antivirus last week. 8gb ram total. 2.1gb is used at idle (with browser open). 3.1gb is used for the first ~4 minutes of running computations with 3 of 4 cores. I normally run all 4 cores, but there is still plenty of headroom normally. HD limit is set at 50gb in Boinc, which is what it has always been. I have 357gb of free space on the drive. Pagefile has always been set variable. Right now it is at 13,824mb with the usual stuff opened like the browser, Boinc (at idle), etc.
5) Message boards : BOINC Manager : Boinc 100% disk activity, locks up (Message 103385) Posted 3 Mar 2021 by tbzep Post: It is my work computer (govt owned) so I can't reinstall Windows. Memory usage looks normal. CPU usage drops a little. At the point where disk usage maxes out, task manager locks up as well. I will play with CPU core numbers and see if that keeps it from locking up so I can get some data from task manager. Edit: Just ran it with 3 cores (six threads) and noticed the memory usage doubled on each work unit as the disk usage climbed to 100%. Using 3 cores gave me an extra 20-30 seconds to watch task manager but it still locked up the system. I didn't made any changes to the system or Boinc settings when it started. I did the update windows update after the problem began. I wondered if there may have been an antivirus update or a change pushed out by our sysadmins. I put an exception in the antivirus software so it would not scan Boinc operations the other day, but it had no affect. Safe mode chkdisk is next.
6) Message boards : BOINC Manager : Boinc 100% disk activity, locks up (Message 103374) Posted 2 Mar 2021 by tbzep Post: I run Einstein on my Boinc manager. In the last couple weeks, it has started causing 100% disk activity and locks the computer up. As far as I know, nothing has been changed to cause this. I have purged work units, updated Windows, and finally, I did a reinstall/repair of Boinc. Nothing helped. When I start it, I get 3-5 minutes of good production with very little disk activity after the loading process. It then goes to 100% and stays there, locking up all functions. Meanwhile, my Linux computer at home has chugged away for about 15 years spitting out Seti and now Einstein work units like clockwork. Win10 Pro 20H2 Boinc version 7.16.11 (x64)
7) Message boards : Questions and problems : Boinc will not suspend with keyboard/mouse use (Message 75702) Posted 4 Feb 2017 by tbzep Post: The keyboard/mouse activity detection was broken on Linux for some time and got recently re-activated again. It should be part of version 7.6.33. Try to install this one. Sadly there is no package for 16.04 only 16.10. Thanks, ChristianB. That took care of the problem. If anybody else wants to do it, I removed 7.6.31 then rebooted before installing 7.6.33. When I tried without rebooting, 7.6.31 ended up being reinstalled. 7.6.33 for Ubuntu is located here: http://packages.ubuntu.com/yakkety/boinc-manager .
8) Message boards : Questions and problems : Boinc will not suspend with keyboard/mouse use (Message 75612) Posted 2 Feb 2017 by tbzep Post: I have both restarted and reinstalled while keeping my work units. I have also tried running it using the web preferences with no change. It keeps chugging along. The settings: Checked - "suspend when computer is in use". I have it set at 5 minutes. That alone should kill it while I am typing this, but it is still running. For what it's worth, I have it set to suspend if non-Boinc cpu use is over 25% and that does suspend it. It starts right back when cpu usage drops just like it should.
9) Message boards : Questions and problems : Boinc will not suspend with keyboard/mouse use (Message 75556) Posted 29 Jan 2017 by tbzep Post: I'm running Linux and have Boinc set to run based on preference with GPU set the same way. It never stops running when I use the mouse or keyboard. I have to manually suspend and resume anytime I want to use the computer. Also tried using web based settings. Ubuntu 16.04 Boinc Manager ver. 7.6.31 (x64) wxWidgets ver. 3.0.2 Intel based machine with nVidia GPU.
