Webb10 apr. 2024 · Abstract: “Shared L1 memory clusters are a common architectural pattern (e.g., in GPGPUs) for building efficient and flexible multi-processing-element (PE) engines. However, it is a common belief that these tightly-coupled clusters would not scale beyond a few tens of PEs. In this work, we tackle scaling shared L1 clusters to hundreds of PEs ...

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. small cute characters

"WebbShared memory If a thread block has more than one warp, it’s not pre-determined when each warp will execute its instructions – warp 1 could be many instructions ahead of warp 2, or well behind. Consequently, almost always need thread synchronisation to ensure correct use of shared memory. Instruction __syncthreads(); " - Shared memory l1

Is `groupshared` memory stored in L2 cache of GPU?

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. WebbWe'll discuss concepts such as shared memory requests, wavefronts, and bank conflicts using examples of common memory access patterns, including asynchronous data copies from global memory to shared memory as introduced by the NVIDIA Ampere GPU architecture.

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.
