Slot-Based Scheduling

January 14, 2023 by No Comments

A slot is a narrow opening or passage. It is also the name for a keyway in machinery. In the modern day, slots are used to receive signals. Slots are also used to manage air traffic in busy airports.

Various companies and industries rely on slot-based scheduling. These methods allow workers to better allocate their time and resources. Moreover, they help organize meetings, appointments and consultations. They are also a way for professionals to establish important deadlines and track positive outcomes.

For financial consultants, for instance, slot-based schedules are a great way to set deadlines and book appointments. Similarly, health care providers use the method to organize staff appointments and consultations. Also, technology firms can use it to track urgent deadlines and plan their objectives.

The mechanism is simple. In general, the overhead of emitted signals connected to slots is much less than the cost of any operation. However, the actual impact of a job on performance can vary depending on the future usage.

Slots can be invoked by any component. They follow normal C++ rules when called directly. But when called through a signal-slot connection, they follow different rules.

Specifically, slots are slower than callbacks. Emitting signals connected to slots is ten times slower than calling the receivers directly. That’s because the connection object needs to be found, which involves overhead. Plus, there’s also the overhead of safely iterating over all the connections. This makes slot-based scheduling a great tool for organizations with complex code.
