The provided codes cpp/pi.c / fortran.pi.F90 calculate approximate value for pi by generating random numbers within a square and calculating how many of them falls within a unit circle.
The code uses combination of OpenMP offloading and CUDA library functions:
- Memory management is done with OpenMP offload constructs
- Random numbers are generated with
curandlibrary - Calculation of pi is done with OpenMP offload constructs
Add appropriate OpenMP constructs according the TODOs in the code. You can compile the code
in Mahti with the provided Makefile by typing make.
(Fortran code uses a custom curand.F90 module for making interfaces to C library routines)
