Some benchmarks done with the software correlator

====== SFXC performance======

A couple of test performed on the adam cluster (6 nodes with one dual-core opteron 246 each).

A) The correlation time as a function of the number of channels {{:scarie:channel_bench.pdf|pdf}}.\\
B) The correlation time as a function of the number of the number of stations {{:scarie:stations_bench.pdf|pdf}}.\\
C) The correlation time as a function of the number of CPU cores {{:scarie:core_bench.pdf|pdf}}.\\

====== SFXV VS DiFX ======

Some benchmarks comparing the performance of SFXC and DiFX, the benchmarks were performed on Adam.
