Parallel computing:
the uses of multiple processors or computers that rely on each other/work together to perform a common task
–Each processor works on its section of the problem
–Processors can exchange information
Grid of problem to be solved
Why parallel computing is impoertant.
- single CPU computing constraint
-performance
-available memory
- Parallel computing allows one to:
-solve problems that don’t fit on a single CPU
-solve problems that can’t be solved in a reasonable time
- We can solve
-larger problems
-the same problem faster
-more cases
•All computers are parallel these days, even your phones has two cores
