Code jams and homework exercises for Parallel Programming in Modern Fortran course at the University of Cyprus
In this assignment, you start writing the world's longest Hello world program with modern Fortran features:
- Blocks
- Deferred-lenth character variables (
character(len=:), allocatable :: foo
) - Collective subroutine:
call co_broadcast(input,source_image=1)
- Write the my_message() function
- Go out for frappe
In this assignment, you will use the co_sum collective subroutine to sum integers across all images.
- Fork this repository by clicking "Fork" in the upper right corner of the browser page (don't click the number next to "Fork")
- Clone your fork and install the sourcery library:
git clone https:github.com/<your-github-username>/UCY-parallel-fortran
cd UCY-parallel-fortran/src/homework2/library
make install
- Complete the steps listed after the text "Assignment" in the file src/homework2/procedural_fireworks/main.f90
- With your working directory set to
src/homework2/procedural_fireworks
, build and run the application using themake
utility:
make
cafrun -n 4 ./procedural_fireworks < fireworks_input.txt
which executes procedural_fireworks
in 4 images and redirects the standard input to the file fireworks_intput.txt
.
- Bring your instructor a frappe to receive an A for the day.
- Generate a pull request on your repository and merge the latest central repository into yours central repository. (Alternatively, you could clone the latest central repository, but you don't have write permissions on it so you won't be able to push your changes, which loses you some GitHub functionality that is only available online.)
- Try building the updated/cloned repository with CMake, e.g.
cd UCY-parallel-fortran-<insert-github-user-name>
mkdir build
cd build
FC=caf cmake ..
make
- The resulting build failure will point you to the new Homework 3 main program, which is identical to the homework 2
main
except that theco_sum_binary
replacesco_sum
and the correspondingresult_image
argument has been eliminarted. - Follow the instructions below the text "Assignment" in the new [main] program to complete Homework 3. A completed assignment will cause all tests to pass when you run
ctest
after the abovemake
