Abstract:
The progress and demand of nanoscience, nanotechnology and molecular electronics is ultimately related to the progress and the perspectives of computational science. We report on the development of a new computing device which was termed 'ABC' with a meaning of 'Advanced Basic-C' compiler/solver. The device uses a double-conversion scheme with the input code of a program formulated in simple terms of the pseudo-basic dialect which is automatically translated into an appropriate C-code and compiled to a stand-alone executable. The C-code can be exported compatible to any of existing computational platforms including Windows, OS/2, Linux or UNIX, to be compiled to a stand-alone executable on a machine with higher resources. Special algorithms are implemented in the routine library of ABC, in particular, the eigenvalue problem for extremely large (of dimension up to 1.000.000 if executed on a standard Pentium PC) sparse Hermitian matrices, and user-friendly routines for multidimensional numeric integration, etc.
