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