c1 c2并不能独⽴立对待 • 要么全部成功，要么失败，否则可能死锁 • 单纯对select结构加锁⾏行不通!!! • 共享⼀一个全局锁？ select • 研究课题：能否实现lock-free channels？ • 使⽤用前获取select中的所有channel的锁 • 按channel结构体的地址顺序加锁 ⼤大纲 • 并发 • 接⼝口 • 垃圾回收 • 调度

Receivers Channel/Queue DLB-Assist Channel removes the penalty of CAS to achieve a safety-guaranteed, lock-free and scalable channel. Intel Confidential Department or Event Name 12 Intel Confidential MiNetRun

liveness bugs add unexpected blocking code, so the obstruction-freedom check will also help with lock-free and wait-free algorithms. Get the full code of the example. See another example where the Michael-Scott
