[OMPI users] MPI for microcontrolles without OS

[Mateusz Tasz]

Hello,

I am a student. I am attracted by concept of MPI and i would like to
apply ths idea to bare metel devices like mictrocontrollers e.g.
stm32. But your solution requires an operating system on board. May I
ask why is it necessary? Can I neglect it? And if so how can I do it?
I ask because I'd like to apply this concept to IoT system where data
can be processed by few device in local neighbourhood.

Thank in advance,
Mateusz Tasz

OpenMPI has been ported to microcontrollers before, but it does require at least a minimal OS to provide support (e.g., TCP for communications). Most IoT systems already include an OS on them for just that reason. I personally have OMPI running on a little Edison board using the OS that comes with it - no major changes were required.

Others have used various typical microcontroller real-time OS on their systems, and porting OMPI to them usually isn’t that bad. May require some configuration mods.

Hi,

Thank for Your answer. Although I am still confused. As I know TCP
communication is not a problem for microcontrollers, so that cannot be
crucial cause for OS choice. Maybe something else is also necessary -
maybe acording memory - do you know?
Do you know where I can find a ported version of OMPI to
microcontrollers(hopefully with documentation :) ? I admit that
having OS on the board is nice and gives a high level of abstraction.
But I belive that sometimes the lower level would be necessary - thats
why I force to find a solutions.
About this ported version - was it working properly?

Thanks in advance,
Mateusz Tasz

A quick web search can answer your quest, I believe - here are a few hits I got (Texas Instruments has been active in this area):

http://processors.wiki.ti.com/index.php/MCSDK_HPC_3.x_OpenMPI_Under_Review <http://processors.wiki.ti.com/index.php/MCSDK_HPC_3.x_OpenMPI_Under_Review>

Several of our members have Raspberry Pi systems running OMPI - looks something like this one:

and here’s a little book on how to do it:

or one of many online explanations:
