Event Based System - Practical Homework

Parallelization

• Threads were implemented in the application in order to parallelize operations. The amount of objects required by each thread to create subscriptions and publishes was shared evenly.
• Especially for subscriptions, the amount of items that must have specific fields was estimated in advance based on the percentages provided as a parameter and distributed to each thread.

Testing Results

• The tests were performed on an Intel Core i7-13700H CPU with 14 cores and 20 logical processors, up to 5 GHz frequency, and 32 GB of DDR5 RAM at 5200 MHz.
