http://stackoverflow.com/questions/17816136/cuda-what-is-the-threads-per-multiprocessor-and-threads-per-block-distinction 


quadro FX 5800 정보 인데요. 


30 multiprocessors x 8 CUDA cores/MP = 240 cuda cores


max. number of threads per multiprocessors = 1024 


그려면 전체 최대 threads 는 1024 x 30 x 8 = 245760  threads 


24만개 쓰레드라는 말인데요.  


이거 좀 이상한거 아닌가요? 설명 좀 부탁드립니다.
