Data ParallelismData Parallelism means concurrent execution of the same task on each multiple computing core.Let’s take an example, summing the contents of an array of size N. For a single-core system, one thread would simply sum the elements [0] . . . [N − 1]. For a dual-core system, however, thread A, running on core 0, could sum the elements [0] . . . [N/2 − 1] and while thread B, running on core 1, could sum the elements [N/2] . . . [N − 1]. So the Two threads would be running in parallel on separate computing cores.Task ParallelismTask ...

The message-passing facility in Windows is called the local procedure call (LPC) facility. LPC is used for communication between two processes on the same machine. It is similar to the standard remote procedure call (RPC) mechanism that is widely used, but it is optimized for and specific to Windows. Windows uses a port object to establish and maintain a connection between two processes, like Mach. Two types of ports are used by Windows: connection ports and communication ports.The communication works as follows −Server processes publish connection-port objects that are visible to all processes.When a client wants services from a subsystem, ...
