The DiFX homepage

DiFX is a suite of programs which allow the correlation of interferometric baseband radio data. It is designed to run on in a cluster computing environment, and uses MPI to enable parallel processing. The main program is mpifxcorr (the actual software correlator) but there are a bunch of associated programs handling geometric model generation, FITS file building etc. DiFX has been compiled and tested on Suse 9.x Linux, but should run on any 32 or 64 bit Linux machine with a 2.6 kernel. DiFX is described in detail in Deller, Tingay, Bailes & West 2007, PASP, 119, 318
