Are there any PRAM simulators?

I want to test some simple pararell 开发者_Python百科algorithms.

There a language/compiler called Fork that claims to have a simulator in the distro called pramsim that's been recently ported to linux. http://www.ida.liu.se/~chrke/fork95.html

Disclaimer: I've no hands-on experience with it.

Please have a look at PRAM Machine Simulator by Adam Stański (the source code is also available).

PRAM is not a very realistic model, ignoring the two factors that make parallel computation so difficult: synchronization and communication. You might have more results looking at Bulk Synchronous Processing (BSP) for example. If you are looking for a practical library, you could look into a Fork/Join style library such as IntelTBB or Java util.concurrency.

edit: To actually answer the question: Sorry, I do not know of any PRAM simulator. I have only seen it used in modified form for complexity-analysis.
