IPCOverhead
IPCOverhead refers to the cost in time and resources associated with inter-process communication (IPC) between processes or threads. It encompasses context switches, transitions between user and kernel mode, data marshalling and copying, protocol processing, and synchronization. Different IPC mechanisms incur distinct overhead profiles, including pipes, message queues, Unix domain sockets, network sockets, and shared memory.
Shared memory often offers low data-transfer overhead because it avoids copying data between user and kernel
Metrics used to characterize IPCOverhead include latency per operation, throughput (messages per second), CPU utilization, and
Optimization approaches aim to reduce IPCOverhead while preserving correctness. Strategies include batching messages, zero-copy transfers where
