Shared memory is a powerful feature for writing well optimized CUDA code. Access to shared memory is much faster than global memory access because it is located on chip. Because shared memory is shared by threads in a thread block, it provides a mechanism for threads to cooperate.

Each thread can allocate from its TLAB without coordinating with other threads, except when it needs a new TLAB. Much work has gone into the sizing of TLABs, and adjusting their sizes based on the application thread performance, to balance the number of TLABs needed, the ...
