10 Nonblocking I/O
In this chapter:
- You learn about message-passing interprocess communication in a distributed network of computers
- You learn about client-server applications
- You learn the limits on using multiple threads or processes in I/O operations
- You learn about nonblocking operations and how they can help hide I/O-bound operations
As processor speeds have historically increased, allowing for the execution of more operations in a given time, I/O speeds have struggled to keep up. Applications today heavily rely on I/O rather than CPU operations, resulting in longer durations for tasks such as writing to the hard disk or reading from the network, compared to CPU operations. Consequently, the processor remains idle while waiting to complete ...
