Numatop uses autotools. If you're compiling from git, run `autogen.sh`
and then `make`. Otherwise, use `./configure && make`.

To install, run `sudo make install`.

To run the test program, run `make check` after compilation or check
the `mgen` program for help information.

## Directories

common:	common code for all platforms.

intel : Intel platform-specific code.

powerpc: PowerPC platform-specific code.

test  : mgen source code. mgen is a micro-test application which can
        generate memory access with runtime latency value among CPUs.
        Note that this application is only used for numatop testing!

kernel_patches: the required kernel patches.


## Supported Hardware

numatop is supported on Intel Xeon processors: 5500-series, 6500/7500-series,
5600 series, E7-x8xx-series, and E5-16xx/24xx/26xx/46xx-series. 

E5-16xx/24xx/26xx/46xx-series had better be updated to latest CPU microcode
(microcode must be 0x618+ or 0x70c+).
