multiprocessor and multicomputer
In the context of operating system build types, "multiprocessor free" refers to an operating system build that does not support multiprocessor systems. This means it is designed to run on single-processor systems only. On the other hand, "multiprocessor kernel" refers to an operating system build that supports multiprocessor systems, allowing for parallel processing and improved performance by utilizing multiple processors simultaneously. The inclusion of a multiprocessor kernel enables the operating system to take advantage of the capabilities offered by multiprocessor hardware configurations.
for improving the efficiency of the computer system.In multiprocessor environment , instructions can be executed parallely.
Multiprocessor systems have gained popularity over the years as they allow the user to do more than they could with a single processor system. Xbox 360, CELL, and Sequent are examples of multiprocessor systems.
The difference between distributed system and multiprocessor system is whether the processing units in the system share the main memory. If yes, then the system is multiprocessor system; otherwise, it's a distributed system.
Transactional Synchronization Extensions was created in 2012.
Multiprocessor
current is load dependent,after synchronization only current will flow
SONET
Because they are completely unrelated things? Synchronization can be implemented with semaphores or mutexes.
synchronization mean arrange all process in sequence for that not occured no colusion in the system.
Interrupts are not sufficient in multiprocessor systems since disabling inter rupts only prevents other processes from executing on the processor in which inter rupts were disabled; there are no limitations on what processes could be executing on other processors and therefore the process disabling interrupts cannot guarantee mutually exclusive access to program state.
