Parallella Community

Greetings,

I recently received an email which suggested the possibility of a project to port the R Statistical language to the Parallella platform using Open CL. While I am a relatively newbie to R , I am member of a large R users group some of whose members might be interested in contributing to such an exciting project for R.

Hi

yes, the idea is to enable R to use the Epiphany parallel processor of the Parallella board as an accelerator, similar to how R can use GPUs as accelerators. One way to do this without having to reinvent the wheel is through OpenCL. just send me a private message on what you have in mind.

Cheers

Hi censix,

Great tutorial on R and OpenCL. I wonder if MPI interface is already available within E16/64 framework, i.e. doSNOW or doMPI

Thank you,
Juan

doMPI is just an R wrapper for MPI, I believe. So as soon as we have a working MPI for the Epiphany we are done.

Thanks. So it means if we manage to install OpenMPI then it would be ready to go? Sorry, I am new to this parallel world

I may have been wrong. looks like 'doMPI' depends on 'Rmpi'. And the latter one I have had not time to look at. You could read the docs and see if it is possible to adapt 'Rmpi' to work with the Epiphany.... Soren

Thanks censix and Andrew, I got answers from both of you

You are correct, my questions came from 2 parts:

- Would MPI be faster than OpenCL, when communicate between the cores on the same board. Though my gut feeling tells me it is OpenCL.
- Next is how to establish the communication between the boards?

Apart from simulation, I am really interested in using this for big-data analysis. Keep up the great works
