Re: wth -- Thread time .vs Subroutine time

@fxm In your "Full code with the 'ThreadInitThenMultiStart' and 'ThreadPooling' Types:" gcc -O2 and -O3 will 'rip out' For J As Integer = 1 To 73000000 Next J To avoid that use less than -O2 or gas. Alternatively with 32-bit and gcc use: (Tip from srvaldez some time ago) For J As Integer =...

Re: EZFree - Easier Windows 10

Can't wait for the EZGui guy's tantrum over this blatant misappropriation of 'his' trademark prefix I do not think that Chris Boss will mind. Gary normally uses gb as a prefix for his apps. Not sure why he didn't on this occasion. I used dr as a prefix for one of my apps on this forum but I cannot ...

EZFree - Easier Windows 10

This is a freeware application written by a PowerBASIC forum member, Gary Beene. Gary is now retired but writes software for 70+ Seniors with vision and physical limitations. Gary is one of the nicest guys that I have ever dealt with, and it is no surprise to me that he does this kind of thing in hi...

Re: wth -- Thread time .vs Subroutine time

Timing random number generators with gcc is a bit of a black art. I have tweaked one test and got the following. CryptoRndII throughput (MHz): gcc 8.3/-O3 for 32bit and gcc 5.2/-O3 for 64bit. 32bit 64bit 445 511 Microsoft 424 476 ThreadInitThenMultiStart 411 460 ThreadPooling (super-new) With the ab...

Re: wth -- Thread time .vs Subroutine time

@fxm Well, you certainly gave it a good try. 'ThreadInitThenMultiStart' is working with CryptoRndII to at least 1TB is readable and easy to use. If it is any consolation if anyone else other than FreeBASIC users want to use thread pooling as CryptoRndII does then they will have to use Microsoft's me...

@fxm In your post Feb 13, 2021 where you use " the current version of 'ThreadPooling' " and " the new version of 'ThreadPooling' " I put the new version to PractRand and got a catastrophic failure at 256MB; three times. I went back to the post Feb 13. I saved the code " the ...

'ptrBaseBuffer1' and 'ptrBaseBuffer1plus' are fixed until a buffer becomes exhausted when we go back to Sub SwitchBuffer.
