CPU Core Isolation

CPU core isolation involves dedicating specific processor cores exclusively to a high-priority task, such as a trading algorithm, by preventing the operating system scheduler from assigning other processes to those cores. This ensures that the trading application has consistent, uninterrupted access to CPU resources, which is essential for maintaining low latency and high throughput.

By removing competition from background processes, the application avoids the jitter caused by resource sharing and cache pollution. This technique is a fundamental practice in optimizing performance for financial derivatives platforms that require microsecond-level precision.

It effectively creates a controlled environment where the trading engine operates without interference from the general-purpose OS activities.
