In the case of shared memory, there is also a set of synchronization primitives needed to allow concurrent access. 1. Cooperating processes require some type of inter-process communication, which is most commonly one of two types: Shared Memory systems or Message Passing systems. A named pipe is allocated for each renderer process for communication with the browser process. An independent process is not affected by the execution of other processes while a co-operating process can be affected by other executing processes. Defining Inter-process Communication • Communication on same PC or Target • Communicate between parallel processes or loops • Offload data logging or processing to another CPU/Core/Thread within same VI/executable • Loops can vary in processing priority • Used to communicate synchronously and asynchronously ACQ LOG High Med Low mutex, waiting. Inter Process Communication in OS There are 2 types of process - Independent Processes - Processes that do not share data with other processes. There are different open standards for IPC today, with the more prevalent standards being Transparent Inter-Process Communication (TIPC) and Multicore Communication API (MCAPI).
