using 100% of cpu

[bwolfsohn]

Reviewing old threads, it doesn't seem possible to determine what cpu an application is running on.

when starting up an app, (and testing it), i'm thinking of showing the cpu via spiking the cpu usage and viewing it in task manager.

This used to work on "slower machines", but it doesn't even cause a blip on my new machine when i test it from xdot

a:={1,2,3,0}
nSeconds:=seconds()
do while seconds() <= nSeconds+2
asort(a)
enddo

any suggestions ??

Hi Brian,

Roger has DC_SetCpu(), which you can set the desired CPU, possibly a start?

Rick,

I'm using that... I want to spike the cpu being used at start-up so i can confirm in task manager that it's using that cpu..

Sometimes, the above function spikes the cpu, sometimes not.. but in my new machines, it hardly ever spikes it..

hi,

what Value do you use for SmpSetCPU() ?

hi,

what Value do you use for SmpSetCPU() ?

nCpu:= val(dc_xtoc(DC_INIREAD('my.ini','something','CPU',@cTemp)))
SmpSetCPU(nCpu)

FUNCTION SmpSetCPU(nCpuMask)
******************
DllCall("Xpprt1.dll",DLL_CDECL, "_sysSetCPU", nCpuMask)

etc etc

nCpu:= val(dc_xtoc(DC_INIREAD('my.ini','something','CPU',@cTemp)))
SmpSetCPU(nCpu)

but what Value does nCpu have ? it must be 2^x

Jimmy,

nCpu is 3

there are 2 physical cpu's and each has 4 cores + hyperthreading.. so, in performance tab of taskbar, there are 16 windows

[Auge_Ohr]

nCpu is 3

please try Alaska Sample c:\ALASKA\XPPW32\Source\samples\solution\smp\smprun.prg

as i can say Description is "old" while 3 for "CPU 1+2" will not work.
it can be only 1 CPU and it must be 1, 2, 4, 8, 16, 32 -> 2^x

[bwolfsohn]

I've also tried 2 with no success

I've also tried 2 with no success

hm ... are those CPU Xeon or "normal" ?
