PureBench32 progress laughable, consistancy question!

This seems to work!

Could you explain it a bit? You buffered the global vars with dummy's but I don't understand it well enough to use in a different situation. Is this only because there isn't much code and any number of globals more than this wouldn't be a problem?

Thanks

With the globals, the results of the two tests can be compared, because they're accessing the same data space, with the same alignment. When you're using normal variables, they're allocated on the fly by pb and can be anywhere in the memory, depending of the order of the new variables when compiling. The "dummy" are, I think, to align a bit more. The test should be better with the floats also global, with the high priority I sent you before, with the same delays, with the ElapsedMilliseconds just before the test. The code alignment would be a must too. As you're comparing pure PB code, I don't see the point to use assembly, just to verify, maybe.
Your new test is nice

Fixed some more bugs...

New Version Has some more features and some fixes.

My PC outputs this:

Starting...
Single thread iterations: 19468
24 Thread iterations: 172203
Difference Multiplier: 8.85x
Cached Disk Writes: 17085
Disk Reads: 897605
2D Graphics iterations: 27463
Done!

My PC with as a 2cpu VM has this

Starting...
Single thread iterations: 14449
24 Thread iterations: 59799
Difference Multiplier: 4.14x
Cached Disk Writes: 10026
Disk Reads: 567543
2D Graphics iterations: 9971
Done!


Needs threadsafe compile option on still... please throw at me any painfully obvious flaws, I'm sure there's plenty
