(moderation:
This is my first time using the BONIC to run einstein@home,but the software make my computer too slowly.The two process 'einstein_S5R1_4.24_windows_intelx86.exe' running with 50% cpu ,and together is 100%.
If you can't resolve the problem I will stop to use the software!
CPU too high
)
BOINC is designed to allow the applications (in this case Einstein@Home) to use your computers unused CPU cycles. Normally this does not cause any problems such as the computer slowing down because the application is set on "low" priority, allowing it to take a back seat to other programs and processes running (which are normally at the default "normal" priority).
By default BOINC allows it's associate applications to run while the computer is in use. You can change this default setting so that BOINC will suspend the application while the computer is in use. To do this go to the Einstein@Home website. Click on the "Your account" link that is on the left side of the page. Under the heading "Preferences" find "General preferences" and click the "View or edit" link. On that page scroll down to the bottom and click the "Edit preferences" link. Under the first section "Processor usage" 2 lines down change the "Do work while the computer is in use" to "no". The next line under that is "Do work only after computer is idle for". Enter the amount of time (in minutes) that you want BOINC to pause the Einstein@Home application (or any BOINC related application that you may be running).
Hope this helps. Welcome to Einstein@Home!

What did you expected from a number crunching software other than to use all of the power your cpu is abled to deliver?
As nevermorestr said the workload of the einstein-app would be lowered to whatever your other application needs as the priority of the einstein-app ist lowest.
RE: The two process
)
And to clear things up about this, the reason why you are running two processes at 50% is because you are running a hyperthreading machine, which presents two virtual processors to your operating system. Windows displays CPU load as a percentage of overall processing power however, so each process can go up to 50% load.

I dare say that E@H runs at VERY slow priority. For example, I ran a perl script in background ( a daemon to be precise ) which checked every 300 seconds my router's address in order to update my dynamic DNS provider. Well... the script uses really far less that 1 second of cpu's time each cycle of 300 seconds; BUT script's priority was HIGHER than E@H... and E@H was practically frozen on 1 of my AMD64 X2.
The lesson is:
1) E@H runs at the lowest possible priority, it won't "steal" any cpu's cycle you'd want to use for yourself (even when the cat plays with thecomputer's mouse, a not very usefull use of computer... but my cat does love it anyway ;-) )
2) Always make a thorough in-depth search-and-look when you debug a script or programm. If everything is running fine, then it means that you haven't spotted the flaw yet. Took me 4 days to discover the error.
