 | | Multiprocessing is also used to achieve increased computing power. | | | As mentioned, these types of locks don't usually require modification for a multiprocessing environment (although the scheduler interlock may come into play when making these resources visible to the scheduler when such a lock is relinquished), but it may be advantageous to introduce additional locks of this type when implementing symmetric multiprocessing. | | | Multiprocessing software determines the degree to which cpus share the workload. |

| | During multiprocessing development, locking strategies were designed to o Reduce the total number of locks per subsystem o Reduce the number of locks taken per subsystem operation o Improve the level of parallelism throughout the kernel At times, these goals clashed: enhancing parallelism usually involves adding a lock to some structure or code path. | | | This task was accomplished by funneling all major subsystems to a single processor while stabilizing the underpinnings of the multiprocessing system (i.e., the scheduler, the virtual memory subsystem, the virtual file system, and the hardware support) in the new environment. | | | On a multiprocessing system, locking a spin lock involves testing the lock location for a value of zero and then atomically setting the value to one before continuing into the critical code section, assured of exclusive access. |

| | Symmetric multiprocessing and cache memory systems are important cost-effective technologies for improving performance in today's state-of-the-art systems. | | | Written for the UNIX kernel developer, this book provides a complete yet comprehensible explanation of the operation of caches and symmetric multiprocessors, how they work together, and the issues operating systems must address in order to run on the machines that incorporate them. | | | It examines the problems these multiprocessors present to the operating system, such as race conditions, deadlocks, and the ordering of memory operations, and looks at how the UNIX kernel can be adapted to run on such systems. |

| | ASMP vs. SMP |
| | In asymmetric multiprocessing the program tasks (or threads) are strictly divided by type between processors and typically, each processor has its own memory address space. | | | The processors are symmetric, that is, they can do anything the others can. | | | Each can look at or alter any element of memory, and each can do any kind of I/O. It is symmetrical because the view from any processor of the rest of the system is exactly the same. |
