The bulk of SCANPS was written between 1989 and 1997 while I was a Royal Society University Research Fellow in the Laboratory of Molecular Biophysics at the University of Oxford, UK. Parallel code for the SGI Challenge and Origin was developed during 1996 on the SGI Challenge at the Wellcome Trust Centre for Human Genetics, University of Oxford. I acknowledge the technical assistance from Silicon Graphics, in particular Nick Camp and Pam Bremer, in helping me get good parallel performance from the SGI shared memory machines.
Development of iterative searching was done at EMBL-EBI during 1999. Development of MMX/SSE code and statistics were done in collaboration with Steve Searle and Caleb Webber. Other developments in progress include an MPI parallel version for Linux and a version for OpenMP.
