Hardware Interrupts

Hardware interrupts are signals sent by peripheral devices to the CPU to request immediate attention, forcing the processor to suspend its current activity. In trading systems, frequent interrupts from devices like network cards or disk controllers can disrupt the timing of critical algorithms.

Efficiently managing these interrupts is necessary to ensure that market data processing is not delayed. Techniques include assigning specific interrupts to particular CPU cores or using polling methods to check for data availability rather than relying on interrupts.

This ensures that the trading application maintains a predictable and deterministic execution path, which is crucial for managing risk and capturing fleeting market opportunities in derivatives trading.
