Hi All, I am begining to learn use of parallel computing for CFD.I want to ask u all what is a Vector Machine? I read some parallel computers are not Vector Machines. Is it true? What's the difference & how does it affect the performance of the two ?

thanks Abhijit Tilak

(1). Vector machine is like a zipper, you prepare the elements in order and grab it and add two long vectors together in a few operations. (instead of picking the element one-by-one. (2). The parallel mechine is to perform similar tasks at the same time, and then exchange information between machines (or processors) when needed. (3). Some operations can be done in parallel independently, while some require certain degree of information exchange. For linear logic problem, you will have to do it one-by-one anyway. (you can't educate your kids before they are born. But you can have many schools to educate many kids. You can also have intensive courses in language or art to train kids in a shorter period of time.)
