Webb26 feb. 2024 · Shared memory is shared by all threads in a threadblock. The maximum size is 64KB per SM but only 48KB can be assigned to a single block of threads (on Pascal-class GPU). Again: shared memory can be accessed by all threads in the same block. Shared memory is explicitly managed by the programmer but it is allocated by device on device. Webb1.2、L1和shared memory是共用的，且可以做一定几种情况的配置，例如48K+16K，或者32K+32K等情况，部分芯片的L1/shared可能比较大，不过单个thread block仍然只能只用48K。超过kernel launch会失败。 1.3、使用L1做缓存的时候，如果启用-Xptxas -dlcm=ca编译模式，需要注意cache的粒度是128字节的，其他情况下是32字节的。 2、Maxwell（ …

WebbL1 and L2 play very different roles. If L1 is made bigger, it will increase L1 access latency which will drastically reduce performance because it will make all dependent loads slower and harder for out-of-order execution to hide. L1 size is barely debatable. If we removed L2, L1 misses will have to go to the next level, say memory.

Webb13 maj 2024 · Nvidia can also change their L1 and shared memory allocation to provide an even larger L1 size (up to 128 KB according to the GA102 whitepaper). But for OpenCL, it looks like Nvidia chose to allocate 64 KB as L1. Past the first level cache, RDNA 2’s L1 and L2 offer lower latency than Ampere’s L2. WebbDifferent from the shared architecture of L1 cache and the shared memory in the conference paper, L1 cache and the shared memory are separated in this paper, which is consistent with that of recent GPUs.
