Your PVM applications must contain the header files that defines all the functions and constants used by the PVM. Programs written in C should include header file pvm3.h, as follows
The Fortran programs should include header file fpvm3.h as follows
- In order to create your PVM executables, you must compile and link them with th appropriate libraries. For example the command
cc/f77/CC [compiler flags] [source files] [loader flags] -L$PVM_ROOT/lib/$PVM_ARCH -I$PVM_ROOT/include -lfpvm3 -lgpvm3 -lpvm3 [libraries needed by PVM] [other libraries]
will compile your program and link it to all needed libraries and include files.
The -lpmv3 is always required in the compile command,
the -lfpvm3 flag is required only in case you are using Fortran,
the -lgpvm3 flag is required only in case you are using dynamic groups.
- A more portable and efficient way to compile your programs is the use of the aimk makefile utility that come with PVM, it is a wrapper program for the UNIX make that determines the PVM machine architecture and sets the ARCHLIB to the necessary system libraries. To keep a portable environment for your PVM applications you can create your own portable aimk makefile called Makefile.aimk and use it to build and compile your codes.
