System: AMD Phenom 9650 quad core
4 GB RAM
Windows 7 64 bit (RC1 build 7100)
400GB hard drive (75% free)

I installed BOINC on Windows 7 (release candidate 7100) 64 bit version. The boincmgr.exe will continually use 100% of one CPU at all times. This is true whether the tasks are limited (I normally allow only 50% usage of the CPU to keep heat down on the phenom chip)

The seti processes are running just fine, and respond correctly to CPU throttling, the boinctray.exe task never uses more than 1-2% of the CPU.

Boincmgr.exe however, consistently stays at 90-100% of a CPU (22-25% of the system) and is very unresponsive.

I do have a CUDA enabled Nvidia card (8400GS) but it's slower than the CPU so I have GPU use disabled.

My only option right now is to kill the boincmgr.exe process and only restart it every few hours to allow tasks to be fetched.

Now hold on.

You say you kill boincmgr.exe ... and boinc.exe keeps running? That means you have BOINC installed as a service, but I thought CUDA didn't work under Vista and above when BOINC was installed as a service.

When BOINC isn't installed as a service, killing BOINC Manager will kill the client. So please explain that one.

Also, how many tasks do you have in cache, both ready to start, running and ready to report? We know that BOINC Manager will take up a lot of CPU (eventually boinc.exe as well) when it's going through a lot of shorties. The real-time data in the manager has to be shown somehow and that somehow will take up CPU.

make sure that the manager is set to normal piorty, under task manger....

I recommend Secunia PSI: http://secunia.com/vulnerability_scanning/personal/

Actually, Ageless, you an tell the client to stick around after you close BM.. there are 2 check boxes in that window that pops up on closing BM.
Close the core clinet and
stop asking the above question on close.
I run all my machines in stand alone but NOT as services. I bypass BM all together. I just launch boinc.exe by its self using a short cut in my startup folder.
This keeps the CPU usage at a bare minimum other then actual crunching.
Seeing how so many dont understand the differences between the GUI and the CORE.. maybe a nice wiki page explaining all this is in order?
Sounds like a job for Nicolas.. he's good at the wikis :)
Peace..

I never noticed that, but just tried it. It seems so. Never had that behaviour before. Must be something new (as in BOINC 6 behaviour).

Not weird I never knew about it as it is a bug, which was introduced with the option that World Community Grid wanted on exiting BOINC Manager and which the developers have no intention of fixing. It has progressed to be an undocumented feature, so to say, one that shouldn't exist.

But then again, you can start boinc.exe in a variety of ways without it showing in a command line window on your task bar. For example, you can start it from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, where it will happily run for each user that logs in and just not run when no one is logged in.

Anyway, I'd appreciate it if certain people would post what they have to say in a less aggressive manner. You can also communicate what you have to say in a civil way.
