deadlock kernel synchronization atomic operation spin locks semaphores 参考文献 An introduction to kernel synchronization 当一个thread正在对数据进行读写操作时,另一个thread对同一个数据进行读写操作,这就会产生冲突竞争,比如重写数据单元等。为了解决这样的问题,必须考虑synchronization的问题。这样的竞争问题,并不总...

The Kernel synchronization delay fuzzing option randomizes thread schedules to help detect concurrency bugs in drivers.Caution This option is not intended for use when you are verifying all (or a large collection of) drivers on a computer. This option should be used only when you are doing ...
parts of the kernel are not run serially, but in an interleaved way. Thus, they can give rise to race conditions, which must be controlled through proper synchronization techniques. A general introduction to these topics can be found in the section "An Overview of Unix Kernels" inChapter 1....
敌方师内部的士兵可以共享情报(shared memory),在某些时候也要确保没有一个士兵掉队从而动作一致(synchronization)。两师遭遇后,真实战斗中,敌方以团(warp)为单位作战,全团成员只服从团长的命令(sigle instruction in a warp)。团长同一时刻只能下一个命令,因此,团长对部分士兵下命令后,其他士兵只能等待,不能分头行动...

(thread block)的数据依赖,很难做算子融合,这是因为在GPU中由一个thread block产生(produce)的数据如果要被另一个thread block消费(consume)就需要通过HBM做同步(global memory synchronization),即需要把产生的数据写到HBM中,然后另一个thread block再从HBM读取,而且这个过程还需要调用一个负责读写的kernel,即除了...
RCU (read-copy update) is a kernel synchronization mechanism that increases a Linux system parallelism by enabling the concurrent access of readers and writers to a given shared data. Although RCU readers and writers are always allowed to access a shared data, writers are not allowed to free dy...
We have implemented AP-RCU in the Solaris kernel (UTS) and experimentally confirmed the expected benefits over traditional forms of synchronization, comparable with previous RCU implementations. The prototype RCU implementation in the UTS kernel, presented in this thesis, is based around a similar ...
