Using https://en.wikipedia.org/wiki/Mmap, a Unix system call that maps files/devices into memory to read metadata from a Large Language Model (LLM) file. This is a small snippet to demonstrate usage of mmap and expects the model file(s) to be in a predetermined format. Implementations are defined in C and Java so far.
This is just a reference implementation for now. To compile, use gcc mmap.c -o mmap and to run use ./mmap /path/to/model.bin. If the argument with the file path is not provided, it will error out saying the number of arguments supplied is invalid.
Java implementation uses MappedByteBuffer created by the FileChannel::map method. To compile, use javac MMap.java and to run use java MMap model.bin. If the argument to the file path is not provided or too many arguments are provided, it will error out.
