[edit] Cg

Make the main program ( for CPU) in C, which loads and run the Cg program ( for GPU ).^[1][2][3]

[edit] Perl

To mix Perl and C, we can use the XS. XS is an interface description file format used to create an extension interface between Perl and C code (or a C library) which one wishes to use with Perl.

The basic procedure is very simple. We can create the necessary subdirectory structure by running "h2xs" application (e.g. "h2xs -A -n Modulename"). This will create - among others - a Makefile.PL, a .pm Perl module and a .xs XSUB file in the subdirectory tree. We can edit the .xs file by adding our code to that, let's say:

void
hello()
  CODE:
    printf("Hello, world!\n");

and we can successfully use our new command at Perl side, after running a "perl Makefile.PL" and "make".

Further details can be found on the perlxstut perldoc page.
