CPU usage

[NudgeyNR]

I have recently setup BoincTasks and was working fine and now the CPU usage is 100% of an AMD 3900X.

Don't know of any changes that have been made to the system. Any help would be great.

BoincTasks shouldn't effect the CPU usage.
You can exit BoincTasks and watch for any changes.
Or pause the tasks and resume it.
There are some BOINC Tasks that use up a lot of CPU and GPU at the same time.
Better wait for a system reboot, to see if that solves the problem.

I monitored task manager in windows 10 (1909) and the boinctask executable is using all spare cpu cycles, even after update of system os and reboot. i am using version 1.80.

• close the BoincTasks window not the program itself and see in the usage drops.
  BoincTasks can be very active if if displays many taks, it goes dormant the moment the display is invisible.
  Using the space CPU is relative, how much compared to the whole CPU usage.

Closing the BoincTasks window made no difference. Is there a theoretical / practical limit as to how many computers it can monitor at once ?

There is no hard limit, it depends on the computer and the remote computers.
If the history is not enables it should be able to handle hundreds.

If History is enabled.
In the History Tab make sure "Move to long term history" is set and the number of days is 2.

OK Go to BoincTasks Settings.
Click on the Expert tab.
Check "Enable thread runtime graph"
Restart BoincTasks.

Wait half an hour and go back to the expert tab and press on Thread graph.
That should show how much of the CPU BoincTasks is actually using.
It shows the main program and all the threads for connecting computer.

I hope i am reading the graph correctly, but i am seeing above 1900% for the Thread  "_BoincTasks"

I hope i am reading the graph correctly, but i am seeing above 1900% for the Thread  "_BoincTasks" 

If it's the vertical axis with % yes.
_BoincTasks is the main program, so something keeps it busy.
What's the load of your computer.
How many computer are connected to BoincTask?

Without Boinc running any wu's around 5%.

Currently there are 348 Computers.  Most of them are NCI instances.

Did you group the computers?
Probably wise to disable the History.

In the computers tab, do you use an IP address?
Do some or all computers connect to BoincTasks as shown in the Computer tab.

[NudgeyNR]

Yes they are grouped.  Each instance of boinc on a computer in one group etc etc.

I use an IP address and MAC address.

All computers / instances connect successfully.

All computers / instances connect successfully.

In grouped I mean the computes , like 50 in one 25 in another.
So BoincTasks is fully functional?

Can you download the following, it does not install.
https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

At startup the BOINC Client runs as child of BoincTasks.
See who is using the CPU BoincTasks or BOINC itself

If you exit BoincTasks
And restart it with e.g. the Explorer, BoincTasks is a child of Explorer and BOINC should now run on it's own.

[NudgeyNR]

The size of the groups range from 50-100 and they are in 5 groups.

"boinctasks64.exe" is using on average 84-85% of the cpu and my system becomes almost unusable. That is with boinctasks only running in the background, not with it opened on the desktop.

I don't use boinctasks to start boinc. i run boinctasks after i have run boinc.

You might want to try disabling your Virus scanner / Firewall to make sure this isn't causing the overhead.

And history is disabled or enabled?
With the history disable BoincTasks should do nothing when minimized.

What you can try is exit BoincTasks.
Open regedit
Computer\HKEY_CURRENT_USER\Software\eFMer\
Rename BoincTasks into BoincTasksx

Restart BoincTasks.
That should set some settings to default, that might help.

Disabling Both firewall and antivirus made no change to the behaviour.

Disabled history, no change.

Made the change to the registry.  Am able to now use boinctasks. CPU usage is still around 85% for "boinctasks64.exe"

Have run full system antivirus scan, nothing found.

Can i backup the computers list and do a fresh install of boinctasks, then restore the computers list ?
