The ChorusOS IPC feature is an optional component of the ChorusOS kernel which can be added in three different configurations:
local IPC. This configuration provides only local IPC communications.
local IPC + remote IPC. This configuration enables local and remote IPC communications to take place over a network data-link such as Ethernet or ATM (Asynchronous Transfer Method). This data-link is also called an external data-link, which means that the data-link driver is implemented within an independent driver outside of the kernel. It is also unreliable.
local IPC + remote IPC over the VME bus. This configuration allows local and remote IPC communications to take place over the VME bus.
The comand-line configuration tool configurator(1CC) is used to set up each configuration.
To configure the local IPC feature:
% configurator -set IPC=true |
To configure the local IPC + remote IPC feature:
% configurator -set IPC_REMOTE=true % configurator -set IPC_REMOTE_COMM=EXT |
To configure the local IPC + remote IPC feature over the VME bus:
% configurator -set IPC_REMOTE=true % configurator -set IPC_REMOTE_COMM=VME |
