BPFS - byte-addressable file system * Requirements For a correct system: - 64-bit Linux (2.6 tested) - FUSE >= 2.8 For development: - 32/64-bit Linux (2.6 tested) - FUSE >= 2.5 * Installation $ make * How to Use BPFS can use a memory-mapped file/device or run in DRAM: - File/device: 1. (File) Create the file. E.g., dd if=/dev/zero of=bpram.img bs=1M count=$N 2. Format the file system: ./mkfs.bpfs bpram.img 3. Mount the file system: ./bpfs -f bpram.mnt $MNT - DRAM (no need to create a file and contents are lost at exit): 1. ./bpfs -s $((N * 1024 * 1024)) $MNT There are several configuration macros at the top of bpfs.h and bpfs.c. You can also profile BPFS's memory write traffic using the Pintool bench/bpramcount.cpp. bench/bpramcount runs BPFS inside of Pin and contains setup directions.
