What do you mean by block and grid in Cuda?


 
             Thread is a single instance of execution. On one SP, one or more threads can be executed. A group of threads is called a Block. On one SM, one or more blocks can be executed. A group of blocks is called a Grid. One Grid is generated for one Kernel and on one GPU. Also, only one kernel can be executed at one time instance.
