I want to know what are the freely available multiprocessor (physical multiple processors) OS available.

I know there are some Linux / Unix variants but don't know any specific one.

Preferably the specific OS with a download link.

Purpose: To experiment with multiple Raspberry Pi clusters to do parallel computation jobs. (e.g. http://www.mersenne.org/)

If possible also suggest some links of POCs for this kind of project.

    You should be more specific about your needs/goals. Are you looking to use multiple computers to split a large task in to a bunch of sub-tasks to be completed separately? Is so, you need an implementation of grid computing rather than a specific operating system. Jan 14, 2017 at 6:22
  • @Basil: My need is to make a small replica of a supercomputer which can be scaled by plugging in more units of Rpi.

  • I suspect you will need to get much more specific about what you mean, to get any helpful answers. Jan 14, 2017 at 6:51

You are actually asking for the wrong thing - you are actually looking for "Cluster Computing" or "Distributed Processing" - and Rasbperrian already supports this sort of processing via python and dispy or numerous other frameworks.

In general all Linux distros share the same kernel. The main differences are the applications installed as standard and the desktop manager. Just ask at https://unix.stackexchange.com/ "Does support multi-procssor".

Don't bother. I looked up the documentation for it

2.1.4. Multiple Processors

Multiprocessor support — also called “symmetric multiprocessing” or SMP — is available for this architecture. The standard Ubuntu 16.04 kernel image has been compiled with SMP-alternatives support. This means that the kernel will detect the number of processors (or processor cores) and will automatically deactivate SMP on uniprocessor systems.
