i remeber for Read only data using constant memory is very fast if in cache. How much constant memory do i have? (i havent found it from any nvidia references). Does it partition into different SM (Cuda core) like shared memory? Otherwise how much texture cashe do I have?
i remeber also, in G80, blocks under the same SM share 16KB shared memory. Does it mean, if my graphics card has 30 multiprocessor, it has totally 16*30=460KB shared memory?
