insert struct file in numerical codes using parallel calculations

I work on numerical codes (numerical solution of NLSW). The solution including different functions (e.g. physical fulx, numerical flux, RHS, ...), some of these functions uses the struct file,have 32 length. the file is as 32 different incident waves. How can I distribute this file, using cluster (32 worker). The codes are work perfectly for only for one file.

Thank you in advance
