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 pdf.
B) The correlation time as a function of the number of the number of stations pdf.
C) The correlation time as a function of the number of CPU cores pdf.
