This message transmission lag delays the entry of threads into the critical section, and the system efficiency decreases.Mutex LocksAs the synchronization hardware solution is not easy to implement for everyone, a strict software approach called Mutex Locks was introduced. In this approach, in the ...
How Hardware Handles Synchronization Emulating Hardware A Sample Operating System Ruediger R. Asche Software ConsultantOctober 1997AbstractThis article describes ways to emulate the synchronization mechanisms found in operating systems (that is, interrupt-driven concurrency and appropriate mutual exclusion pri...

Specifically, we focus on several of the new thread synchronization features introduced with the new operating system: condition variables, slim reader/writer locks, and one-time initialization. Condition Variables The condition variable has existed in other threading libraries for some time and has ...

Different applications utilizing NVIDIA swap-sync functionality need to be split in terms of sync groups, or for two separate clusters running on the same hardware. Additional Comments A 0 value is not allowed. A 0 value is used internally to detach/leave a group/barrier. Only natural numbers...
lock and a sequence number. The spin lock is used to protect the list while entries are inserted or deleted. The sequence number is incremented each time an entry is inserted or deleted. On some hardware architectures, using a sequence number enables these routines to avoid using a spin lock...
