A Fetch&Inc object stores a non-negative integer and supports a single operation, fi, that returns the value of the object and increments it. Such objects are used in many asynchronous shared memory algorithms, such as renaming, mutual exclusion, and barrier synchronization. We present an ...

Elements of Datapath for the fetch and increment The first element we need: a memory unit to store the instructions of a program and supply instructions given an address. The program counter (PC), which is a register that holds the address of the current instruction. Lastly, we will need a...

putIndex(AtomicLong):通过getAndIncrement取得下一enqueue操作的元素位置。 popIndex(AtomicLong):通过getAndIncrement取得下一dequeue操作的元素位置。 注意,这里的putNode和popNode只是引用了单链node上的节点,随着程序的执行,它们会尽量更新为最新的节点。
void refcount_increment(RefCountedObject *obj) { __sync_fetch_and_add(&obj->ref_count, 1); } // 减少引用计数 // 如果引用计数减少到0,释放对象 void refcount_decrement(RefCountedObject *obj) { if (__sync_fetch_and_sub(&obj->ref_count, 1) == 1) { ...

simply by incrementing the turn such that the next waiting thread (if there is one) can now enter the critical section. Note one important difference with this solution versus our previous attempts: it ensures progress for all threads. Once ...
This fetch script is used to copy the incremental crawl output files to the appropriate directory for a partial update. The script is included in this section, with steps indicating the actions performed at each point in the script.
