On the outside chance.....maybe an event of dual core.....but that should/could report 50%....stumped, but to be sure the system variable needs to be set in the Systems Variable section, not the User variable section. You have to boot to let it take effect....maybe  PS i run the enigmatic HT version of a P4! It doesn't even report 60% it keeps going between 47 and 50 (sorry I said 60 earlier, I was looking at the total CPU usage in the Performance tab, rather than at the single WCGrid_AutoDock.exe CPU usage in the Processes tab). So yeah, it doesn't go over 50 at all. Both northwood pc's have wcgrid_max_cpu in the system variables section and both have been rebooted.. still.. nothing  I guess it's kind of like Prime95 if you're familiar with it. If you use that on an HT processor, you have to run two instances to get it to 100%. Each Prime95 instance will only use 50%. |

Hello Youssef Abdelaal,
On a Hyperthreading Pentium 4, 50% is 100%. Remember, hyperthreading allows a CPU to run 2 threads, so if the CPU is 100% utilized, Task Manager divides that by 2 and says that it is 50% utilized.  That is just the way that Task Manager reports on a hyperthreading CPU. So you ARE running 100%.  Lawrence |

Hello Youssef Abdelaal , There are 2 places where the throttle variable is set. According to Rick Alther ( http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=7712#62035 ) the registry value has priority over the environment value. ' WCGridMaxCPU.exe -t 100' should set both values to 100%. Lawrence I just tried that, but both values had already been set to 100, the registry one was set manually. It still doesn't use more than 50% total (100% of any one of the "two" CPUs it thinks there are). This thing needs to start supporting dual core  oh well..Thanks |

Last, an off chance. I dont know if the throttle tool allows for the Registry variables to be deleted....i went in and performed the dangerous manual act, after it did not do what i expected, but strictly speaking 50% is 100% of one virtual core...Taskmanager does not know i suppose.
----------------------------------------The Throttle tool actually does read the environment variable btw. It offers to assume that value when u use it. Of course, there is BOINC that uses both cores, but not on an HT....i've not been able to coax it to do that, so run UD+BOINC side by side to get the max. ciao

If you want to utilize 100% of CPU on the Dual cored or HT machine, use BOINC to run the grid. Boenic can assign 1 task for each CPU so if you have 2 CPU, BOINC runs 2 task at a time and causes the CPU utilizations to go up to 100%. It does now show the graphic though, work well.
