Sum of Array using Multi-threading (pthreads)

• A simple program utilizing multi-threading to calculate the sum of an array using 2 techniques.
• This program is beginner-friendly and should be implemented by folks starting to work with multi-threading to get the hang of it.

Methods:

1. Using local variable

• This method allows for faster calculations since each thread does not have to wait for the memory resource

2. Using global shared variable

• Implementing using a global variable requires the use of mutex or similar resource management techniques on the critical section of the code to achieve concurrency and avoid bad reads and potential deadlocks.
• Since each thread has to wait for the resource, the compute time naturally goes up.

Workload Division:

• The workload is divided equally among the available threads.
• If any workload remains after maximum equal assignment to each thread, the extra workload is assigned to the threads in a round-robin fashion.

Pre-Requisites:

• pthreads library.
• Use the pthread flag when compiling the code.
• See Guide.txt regarding running pthreads library in Windows.
