Nettet22. des. 2011 · Definite YES. Graphic cards offer parallelism, and switching from CPU to parallel computation on GPU can save a lot of time. A linear time algorithm can have a monumental speedup when executed in parallel. See GPGPU and "applications" section, or google for "graphic card computation". NettetAmdahl’s Law¶. Amdahl’s Law is a formula for estimating the maximum speedup from an algorithm that is part sequential and part parallel. The search for 2k-digit primes illustrates this kind of problem: First, we create a list of all k-digit primes, using a sequential sieve strategy; then we check 2k-digit random numbers in parallel until we find a prime.

NettetAmdahl's law is a widely used law used to design processors and parallel algorithms. It states that the maximum speedup that can be achieved is limited by the serial component of the program: , where 1 – P denotes the serial component (not parallelized) of a program. This means that for, as an example, a program in which 90 percent of the code can be … NettetInherent Non-Parallelism Amdahl's Law 1 S of program is inherently sequential ⇒ Speedup < S • 50% sequential ⇒ maximum speedup of 2 • 90% sequential ⇒ …

NettetWe can calculate T (1) = 4+5+60+5+1 = 75. A formula to compute the time in parallel would be T (p) = 15 + 60/p since the 60 minutes for section 3 will run in parallel over p processors, while the remaining 15 minutes only runs on one processor. Using this equation, here is what happens to speedup as you increase the number of processor …
