We have shown that by using the netCDF libraries we were able to decrease I/O time and reduce the file sizes of both input and output files relative to the original implementation using ASCII case. We have merged these additions to the main trunk version of the code of CCPForge such that Prof Fagan's group may make immediate use of them. The impact of this work is that it is now feasible to use HECToR as a platform for running PARA-BMU rather than small-scale local clusters; this paves the way for bone modelling at unprecedented scale and accuracy.
