1) Message boards : The Lounge : Laptop cooling ideas (Message 109914)
Posted 29 Sep 2022 by carmar
Post:
I run boinc at 100% so cooling ideas are always helpful. I didn’t see a thread on this topic - did a general search for “cooling”. Here are mine to share - not the best ideas but any critique should be to my benefit. Others can post their ideas or tell me “WTH are you thinking??!!” 🙂

I have two machines that I use.
1. Toshiba satellite (occasionally) - Copper cooling channel was easy to access by cutting out some of the bottom panel. Fixed small aluminum heat sinks over CPU & GPU interface of copper. Of course, now I have to elevate with enough clearance for the fins but I can even get the laptop fan to stop when I blow enough air over the fins with boinc running (at helpful ambient temps, of course 😉 ).

2. Daily driver - https://www.newegg.com/gateway-ne56r34u-everyday-value/p/N82E16834101303
Put this one on a metal box with fan intake port exposed and port grill removed. Removed front panel that covers the memory & drive bays. Finally, I have a desktop case fan (hooked to separate 12 v supply) blowing air into the exhaust vent fins. At night I turn off the external fan since the ambient temperature drops and since the fan is noisy.
When I opened up this machine, it looked like a nightmare to get to the CPU, so I resorted to just cooling the exhaust vent fins.

Feel free to share your ideas on your own setups or mine.

In the interest of a record for future reference, summarizing what I’ve learned. The disappeared tasks issue can be mitigated (no guarantee to eliminate) by one or more of the following:
1. Shutdown boinc and avoid use when accessing the internet through a different network.
2. Preferring File -> Exit Boinc Manager as the mode to shutdown Boinc as well as Shutting down the computer (reboot’s helpfulness is iffy).
3. If you have just added a project that has zero new tasks (even if you’ve done work for it in the past but just newly re-added it), remove it until you definitely get new tasks for it.
4. Use the file deletion method I referenced in my prior post, shutdown machine, boot up.

Thanks, Bryn.

This week after adding LHC, the "Disconnected" problem resurfaced.
Instead of reinstalling I simply went through the home folder and deleted the following (anything that seemed tied to boinc):
https://tinypic.host/i/boincdelete.AG0G8

Hope this helps as a much easier future solution.

PS - 2-3 files may not have been boinc related but erred on the side of caution and then boinc manager was fine after that.

The .BOINC folder and .BOINC Manager text file both persisted into this installation that works. Additionally, there’s a BOINC Manager-<username> file. I don’t recall seeing this third file last time but I can’t be certain.

I’ve had no problems since, as noted in my last post.

Hope this helps.

Closing the loop on this by confirming what worked for me (YMMV).

Short answer: Shutdown BOINC manager and client before leaving home network and keep them off until you return to home network. This works for me because my laptop rarely leaves the house.

Long answer: Reinstallation alone doesn't fix the problem. Use Synaptic Package Manager (Complete Removal option) or
sudo apt purge
. But this only removes files in root, not in home. For home, you have to intensively go through each file and each subfolder. There were files in the home folder and subfolders that didn't have "boinc" anywhere in the names. For example, a file in home named "processedtasks" and a subfolder in home named "projects". The names will give you hints that these are for boinc but will not show up in any searches for "boinc". Most of the files I removed were XML, a couple of text files. There was also a ".BOINC" hidden folder and a ".BOINC" text file. Yes, hidden files need to be made visible (ctrl+h for nautilus, nemo, thunar). I also used BleachBit after the Synaptic removal step and before this manual intensive home folder cleanup but I'm not sure if BleachBit is necessary. Once all this is done, reinstall boinc manager, add your projects, run the tasks, reboot to test, voila it works.

Hope this precludes, or at least alleviates, headaches for some users in the future.

Thanks.

In addition to entering a password in the gui_rpc_auth.cfg file, I tried all the steps up to this point: https://boinc.berkeley.edu/forum_thread.php?id=14013&postid=103913#103913 - this one didn't make sense to me so I didn't try it. I also set permissions to both BOINC folders (in etc and in var/lib) to have the client get full create and delete permission. Also added myself (only user) to boinc group. The manager stays disconnected.

I think the easiest fix, until I get tired of it, would be to just manage my tasks so that if I go to another location (which I rarely do) I don't lose any work. And then I'll just purge and reinstall as necessary.

Update: that didn’t last. On this morning’s boot, nothing showed under project list. Thankfully I haven’t run any tasks since starting this thread.

I have now completely removed boinc, including folders, and done a fresh install. I am now running some tasks. I will report back if I learn anything new. If the problem persists, I may just quit boinc since I haven’t had luck searching for solutions to this problem - it seems very unique.

Thank you all for your help.

An update. On the same thread I cited earlier, I tried the commands listed here: https://setiathome.berkeley.edu/forum_thread.php?id=84654&postid=2011927

When I run only
sudo systemctl stop boinc-client
and then launch Boinc manager, MLC shows on my project list. None of my older tasks (which it seems were either sent or abandoned) but at least the project shows. I think there does seem to be a second client/account run as you suspected but I don't know how.

The first time when I managed to connect, I had to get MLC back on the project list from scratch. It is the only project though, and I used the same email and password that I had in account with MLC.
However, before I managed to connect with File -> select computer , I had tried entering my system user and password (rather than leave both blank). I didn’t get anywhere with that but maybe the information helps you ? I don’t know.

PS - my main concern is that if I run some tasks here, shutdown, and go back to my own network, boinc manager may again wipe out my tasks. Or if it may happen even without switching networks if I happen to shutdown. I haven’t run any new tasks since this happened.

It shows nothing, blank.

Thanks for that. I checked. Some tasks did go through, that's a relief. The rest were all abandoned. Not a big deal, however, now when I shutdown and started up a little later, I again got the Manager showing as disconnected. I'm still not on my home network. How should I resolve this properly so I stay connected the next time I decide to shutdown and boot up later?

PS - Sorry, just saw your second post. I found ".BOINC Manager" in my home folder and deleted it after I exited the Manager. Starting it up it still shows as disconnected. There's a Boinc folder in my home folder but that has "stderrgui.txt" and "stdoutgui.txt"

Hi all.

I've been running https://www.mlcathome.org/mlcathome/ on Zorin 15 (Ubuntu 18.04) using Boinc manager version 7.9.3.

Last night I set it to not receive any more tasks - it had several on my laptop that were continuing to be processed and I left them running. I had turned off my router overnight and this morning had a few tasks finished but not yet sent to the server since my router was off. I have done this before numerous times and once I reconnect the router the tasks get transmitted just fine. Anyway, I shutdown the laptop in the morning.

Later in the morning, I connected to another router at a different location (trusted). Boinc manager wouldn't start. I used the command here to stop Boinc https://setiathome.berkeley.edu/forum_thread.php?id=84654&postid=2011880 since I could tell based on the CPU usage that the client was running but the manager was not launching.
This allowed me to launch Boinc manager but it showed Disconnected. I used File -> connect to client and just clicked OK (blank) and then had to start again to connect to MLC. Manager connected to MLC, showed no credit, then after about a minute showed my correct credit.

But my tasks, processed and unprocessed, are all gone. This is where I hope you can help me - is it possible to get those back on or have I lost them?

Thanks.
