We present Open Multi-Processing (OpenMP) version of Fortran 90 programs for solving the Gross-Pitaevskii (GP)
equation for a Bose-Einstein condensate in one, two, and three spatial dimensions, optimized for use with GNU and
Intel compilers. We use the split-step Crank-Nicolson algorithm for imaginary- and real-time propagation, which
enables e cient calculation of stationary and non-stationary solutions, respectively. The present OpenMP programs
are designed for computers with multi-core processors and optimized for compiling with both commercially-licensed
Intel Fortran and popular free open-source GNU Fortran compiler. The programs are easy to use and are elaborated
with helpful comments for the users. All input parameters are listed at the beginning of each program. Different
output files provide physical quantities such as energy, chemical potential, root-mean-square sizes, densities, etc. We
also present speedup test results for new versions of the programs. |
