POE Lab Exercise: Question 1 Solution

Solution to Question 1

C version:

First compile hello.c:

cc -o hello hello.c For practice, you can compile the sample program with one of POE's compiler scripts, although the sample program contains no message passing calls:

mpcc -o hello hello.c

Fortran version:

First compile hello.f:

xlf -o hello hello.f For practice, you can compile the sample program with one of POE's compiler scripts, although the sample program contains no message passing calls:

mpxlf -o hello hello.f Note for HPF programmers: The steps shown in the rest of this lab exercise are useful for all parallel programs, including HPF programs, but because of the way HPF handles output, the sample program provided here does not produce interesting output if compiled with pghpf or xlhpf. A later exercise will introduce you to the use of those compilers.
