Shared Memory Architecture (pthreads)

System-critical

• Implement relaxation technique sequentially
• Run relaxation in a single thread
• Implement relaxation on multiple threads (lock array for now, no need to be efficient)
• Find 100% sequential code from past commits and store in own file
• Implement relaxation on multiple threads efficiently (sync float array with mutex array to lock individual values)
• Polish code for batch submission on Balena (print parameters and time at the end).
• Set number of threads from command line input.
• Gather data in an Excel spreadsheet and plot it in a graphs.
• Write report in LaTeX

Code design

• Move all code from the main() to individual functions.
• Move log print statements to own funciton.
• Create a makefile for compiling the code with GCC then running it.
• Move array-related functions in own C file.
• Move print-related functions in own C file.
• Refactor code to fit all within 80 chars per line.
• Use global value for "debug mode" to activate/deactivate print statements (and surround print statements with if statements).
• Use floats instead of doubles.
• Remove global function definition in main().

Balena

• Add email address in job script for notifications when job finishes running.

Distributed Memory Architecture (MPI)

• Implement basic MPI code
• Fix warnings
• Move helper code into separate source files
• Replace duplicate hard-coded code with loops
• Take user input from command line to determine parameters
• Measure time (using MPI_Wtime)
• Implement relaxation in child processes
• Gracefully exit program (uses "exit(0)" and "mpirun -quiet" for now)
• Gather data on Balena
• Write report
