// ( cluster_size == 1 ) implies no distributed shared memory, just thread block local shared memory int cluster_size = 2; // size 2 is an example here int nbins_per_block = nbins / cluster_size; //dynamic shared memory size is per block. //Distributed shared memory size = cluster...
Shared memory features a broadcast mechanism whereby a 32-bit word can be read and broadcast to several threads simultaneously when servicing one memory read.request. This reduces the number of bank conflicts when several threads read from an address within the same 32-bit word. More precisely, ...

避免的bank conflict的一种方法是对shared memory使用padding,通过在尾部padding一个元素,数组变为s_data[32][33],这样相同列的不同行的元素的bank值不再一样,在转置时就避免了bank冲突。如下图所示: 新的代码如下: __global__voidmatrix_trans_shm_padding(int*dev_A,intM,intN,int*dev_B){introw=blockI...

3、 共享存储器 shared memory 可以被同一block中的所有线程读写 特点:block中的线程共有;访问共享存储器几乎与register一样快. //u(i)= u(i)^2 + u(i-1) //Static __global__ example(float* u) { int i=threadIdx.x; __shared__int tmp[4]; ...

我这里重点不在bank conflict,而是主要讨论shared memory和 memory bank的对应关系。 文中有这么一段描述: Example Scenario Let’ssay we have an array of size 256 of integer type in global memory and we have256 threads in a single Block, and we want to copy the array to shared memory.Therefore...
Shared Memory Example Declare shared memory in CUDA C/C++ device code using the __shared__ variable declaration specifier. There are multiple ways to declare shared memory inside a kernel, depending on whether the amount of memory is known at compile time or at run time. The following complete...
