README
About
AzureMARS is a versatile Core War simulator written in Free Pascal. Tested on x86-64 under Windows and Linux, may work on even more platforms.
Compiling and Usage
AzureMARS can be used in four different modes:
- as a standalone binary
- as a library
- as a FreePascal unit
- as a Julia module via provided bindings.
Standalone Mode
Compile with fpc -O4 -oAzureMARS Main.pas, use with AzureMARS [options] file1 file2. Options mostly mirror PMARS. Only two-warrior matches are supported. Warrior compilation is not implemented, input files must be in load file format. Available options:
| Arg | Type | Description |
|---|---|---|
-r |
Integer | Number of rounds |
-s |
Integer | Core size |
-c |
Integer | Cycles until tie |
-p |
Integer | Max. processes |
-l |
Integer | Max. warrior length |
-d |
Integer | Min. warriors distance |
-h |
String | Hill preset, one of nano, tiny, 94nop |
-P |
Permute starting positions | |
-Tp |
Test performance | |
-Tc |
Test correctness |
Library Mode
Compile with fpc -O4 -dlib AzureMARS.pas. See the list of exported functions at the end of AzureMARS.pas. Calling convention is cdecl.
FreePascal Unit
Place AzureMARS.pas in your project folder, import with uses AzureMARS. See the interface section for documentation.
Julia Module
Place the compiled library and AzureMARS.jl in your project folder, then use as
include("AzureMARS.jl")
using .AzureMARSUse the REPL help mode to see the documentation of exported types and functions: help?> AzureMARS.
Performance
All tests performed with stock Ryzen 5950X. Built-in performance test: Nano 102 MIPS, 94nop 108 MIPS.
Comparison against other simulators, 4000 rounds, random warrior positions, time in seconds:
