libdsmu was tested on Ubuntu 14.04 x86/64 running the 3.13.0-24-generic kernel. Older kernels on a non-x86/64 machine probably will not work because the code that detects fault types is non-portable.
Third party libraries:
$ sudo apt-get install libb64-dev
$ cd src
$ make
$ python manager/manager.py &
matrixmultiply uses the alternation-style sharding algorithm for nodes-to-rows mapping, while matrixmultiply2 allocates rows to nodes in contiguous chunks to reduce the effects of page thrashing. They are both launched the same way.
First, start the manager:
$ python manager/manager.py &
Next, start up instances of matrixultiply in parallel. To start three instances, launch them like this:
$ cd src
$ make
$ ./matrixmultiply2 127.0.0.1 4444 1 3 && \
./matrixmultiply2 127.0.0.1 4444 2 3 && \
./matrixmultiply2 127.0.0.1 4444 3 3:
