Nature of problem:In high energy physics the numerical integration package is used to obtain the cross section for the physical process. When the physical process is complicated, the integrand may become a very long Fortran source code. In such a case, the integration itself requires too much CPU time for practical use. | ||

Solution method:We have developed a program package VBASES, a super computer version of multi-dimensional integration package BASES. By using VBASES, we could shorten the CPU time by factor 80 of the integration of the radiative Bhabha scattering. | ||

Running time:The running time depends especially on the length of the integrand subprogram which gives the differential cross section for the process. |
