Re: Seeding PRNGs with the Time Stamp Counter

So, there we have it. A bloke who has knocked out more than his fair share of PRNG implementations believing in randomness ending up being, how can I put it, uncertain whether randomness actually exists? Through the years I have followed your threads about rng's with interest and the topic of rando...

ARM CPU + FreeBASIC?

Hello all,

Soon we will have Windows laptops with ARM CPU, for example the "Snapdragon X Elite". Any idea how such a CPU would play with FreeBASIC? Will it run our x86 programs? And will GCC recognize the arch and optimize / generate proper code for it with the march=native flag?

Thank you

Example of the Manual polyalphabetic solver: You use this solver when you have a good idea or suspicion of how the polyalphabetism in the works. Or if you want to repair a message. 1) Example cipher, put it in the Input window: xfkkthbnkyovtonvd hidhotfhfrfortfvf rbkrfbtontbdtvbkk yfirttoffikovfhfr ...

Re: Parallel for loop in freebasic idea

You may have a hybrid CPU where some cores don't have hyperthreading. I know it's besides the point of your thread but with such a CPU make sure that in Windows under Power settings, you have selected the best performance scheme (Beste prestaties) or Windows will offload your FreeBASIC program to th...

Re: Missing in action.

Thanks deltarho/Lothar/srvaldez. I am still here, but only half. My wife died on Sept 7 after an horrific but short illness. (a few weeks). She was buried on Sept 18 in Stoneykirk Cemetery, a few hundred yards from our home. Sorry I missed the first "Missing in action" post, I am a little...

Re: Working with bits

Thanks srvaldez,

It worked but it was slower, probably because the ASM interrupts the GCC optimizations.

Re: Working with bits

One other issue of working with bits is that bit retrieval is slower than getting the value from a normal array. Because underlying bitwise arithemetic is used to retrieve the n'th bit from a data type. It posed to be a bottleneck for my specific use. For example: a+=bit(array(x+y),n) 'slower a+=arr...

Re: Working with bits

hello Provoni :) the sum of bits in an integer is known as population count or POPCNT you can use the gcc __builtin_popcountll function or use the FB version by dodicat https://www.freebasic.net/forum/viewtopic.php?p=299802#p299802 to use the gcc builtin you must compile with the gcc backend, -gen ...

Working with bits

Hey all, For an algorithm I'm trying to work with bits as fast as possible. Here's roughly what I need and any hints and tips are welcome. Currently working with 64-bit integers but could be persuaded to work with 32-bit numbers if that would provide other benefits. 1) Need to set bits possible (gen...

Thanks, I have absolutely no idea where these files are supposed to go. It put them in the root of my program but that didn't work.

Re: Programming Languages Benchmark

What operating system? You need the GSL shared libraries installed or downloaded. They are not part of FreeBASIC. If on Windows, are you doing 64-bit or 32-bit FreeBASIC? I have dlls for both 32 and 64-bit windows that are known to be good; they are part of my Fedora Linux distribution stock packag...
