Improve Software for More Logical Processors - DONE

[Dave1394]

I am running this tool on a Dual Quad Core system on Win7 x64. It only lets me stress Core 1 and Core 0. I recommend improving this software so that it gets a list of all Logical Processors in the system and allows you to stress them all. I would like to stress any of my 8 cores or all of them. Also, Logical Processors is a better description than Cores because if I used this tool on a HyperThread enabled processor, I can stress the logical processors as opposed to the cores.

Thanks. We will add the feature. At the time the software was created only CPU's with 2 cores were available.

I think 'core' it is more popular than 'logic processor'. Google returns only 20000 results for 'logic processor' and many many millions for 'cpu core'.
Most people count their processing units in 'cores' not in 'logic processors'. It is not about technique - it is about marketing.

Done.
Application supports now up to 8 cores.

Application supports now up to 16 cores.

Thanks for the quick improvement. As for the "Logical Processor" vs. "CPU Core" terms, I agree, from the point of view of marketing, you are right, but from the point of view of "technically correct", both are useful. For example, in Win7 MSINFO32, I see this on my PC:

Processor Intel(R) Xeon(R) CPU X5482 @ 3.20GHz, 3192 Mhz, 4 Core(s), 4 Logical Processor(s)
Processor Intel(R) Xeon(R) CPU X5482 @ 3.20GHz, 3192 Mhz, 4 Core(s), 4 Logical Processor(s)

Even Microsoft improved their tool to show reality. I found out how to programmatically get the number of cores vs. logical processors. Take a look at this open source project:

When you get it to compile, it can extract both of these. The Windows API for SetAffinity() only thinks in "Logicla Processor" terms. The best improvement you could make to the software is to list the cores, then list a subset of logical processors for each core when the Logical Processor count is larger than the Core count. The trick I do not know yet is if the Logical Processor count, for example is 8, and the Core count is 4, I think this is true, but I never did research to check:

SetAffinity() to Logical Processor Index 0 is to Core 1, HyperThread Core 1.
SetAffinity() to Logical Processor Index 1 is to Core 1, HyperThread Core 2.
SetAffinity() to Logical Processor Index 2 is to Core 2, HyperThread Core 1.
SetAffinity() to Logical Processor Index 3 is to Core 2, HyperThread Core 2..
SetAffinity() to Logical Processor Index 4 is to Core 3, HyperThread Core 1.
SetAffinity() to Logical Processor Index 5 is to Core 3, HyperThread Core 2.
SetAffinity() to Logical Processor Index 6 is to Core 4, HyperThread Core 1.
SetAffinity() to Logical Processor Index 7 is to Core 4, HyperThread Core 2.

Anyway, just a suggestion for further improvements. For now, what you made is good for me.

Actually, I just tested your newest program. On my 8 Core machine, when I do Test All or select Cores 1-8, Core 6, 7, and 8 do not get stressed. You may want to check this. Also, you may want to disable (gray out) the selections which don't apply to my machine. If I only have 8 logical processors, then having 9-16 enabled doesn't make sense.
