Short: Bench a Mandelbrot set in a console
Author: Dino Papararo (Dino.Papararo@gmail.com)
Uploader: Dino Papararo (Dino.Papararo@gmail.com)
Architecture: ppc-amigaos; ppc-morphos
Requires: AmigaOS4 or MorphOS compatible Amiga computer
Version: 2.4 (14-May-2020)
AsciiMandelbrot - coded by Dino Papararo (Fl@sh) 29 apr 2018. Based on ascii
mandelbrot app taken over the web, it's the only one I know to use altivec
extensions, and for OS4 version GMP Library, to draw an ascii mandelbrot set
in a console :-) It was developed on QEMU/WinUAE AmigaOS4 and MorphOS
(PowerMac g5 quad), mainly for testing and benchmarking purposes. I hope this
can be useful to test in a fast way FPU and Altivec speed of PowerPc cpus.
AsciiMandelbrot is compiled with GCC v8/v9 to run under AmigaOS4 and MorphOS.
It's also easily portable to other platforms like Linux, MAC OSX and Windows
OS. C Source code is included, to compile it just type MAKE in the shell :-)
Usage: AsciiMandelbrot iterations rows cols - where iterations is number of
iterations (default 100000), rows is number of printed rows (default 100),
cols is number of printed cols (default 100) AsciiMandelbrot -? for help
New in this 2.4 version (14-May-2020) * Optimized even further Altivec routines
New in this 2.3 version (10-May-2020) * After many researches and tests now
Altivec routines are speeded up to 3x, processing 4 pixels per instruction!
New in this 2.2 version (04-Apr-2020) * Added GMP Library support only for OS4
MorphOS version is not changed because there isn't a porting of GMP Library
New in this 2.1 version (3-Nov-2019) * Default iterations lowered to 100000
for fast results on slowest machines
New in this 2.0 version (26-Oct-2019) * Now it's compatible with MorphOS! *
Added some input controls * Some bugfixes and a lot of code added/rewritten
New in this 1.5 version (20-Dic-2018) * now rendering engine and resulting
computation time is separated from printing text routine on console window
New in 1.4 version (03-Nov-2018): * One executable for both Altivec and non
Altivec routines, so no more crashes if you run the wrong exe! * Now you can
choose the number of iterations. * Elaboration time is printed on screen for
speedtest purpose for bot Altivec and non Altivec calculations. * Added a new
charset to draw the Mandelbrot set.
