每个block最大的threads数为:2014 Maximum number of threads per block: 1024 这里我们是一个二维的threads,所以每个维度最大为32.同理三维的也是一样的。
首先,如何根据ThreadsPerBlock和RegisterPerThread计算Theoretical Occupancy? 假设预先设置ThreadsPerBlock,可以得到WarpPerBlock 计算BlocksPerSM=RegisterPerSMRegisterPerThread∗ThreadsPerBlock(注意整数相除,下取整) 计算WarpsPerSM=WarpsPerBlock∗BlocksPerSM,对比该值与MaxWarpsPerSM,是否达到100%。 上述计算中,Regis...

Lots of percpu_rw_semaphore readers are blocking before starting those critical sections whereas the writer sets the sem->block to 1 for writer-writer exclusion then waiting for all active readers to complete. A possible cgroup_threadgroup_rwsem deadlock. Solution Unverified - Updated June 13 ...
