Parallella Community

Great!!!
Could EPython combine with Jupyter or IPython ? Thanks.

Hi - yes it should be possible especially as the source is available for both. Sounds like it would be an interesting project, let me know how you get on with this and if you have any questions/problems.

This is excellent! Exactly what I needed to begin learning how to use the epiphany chip. Will this work with libraries such as numpy scipy etc.?

When I run this on my Kickstarter board I have a problem:

parallella@parallella:~$ epython hello.py
epython-host: ERROR: SREC file support is deprecated. Use elf format.

Error loading Epiphany program

Any ideas what is going wrong?

Use the 2016.3.1 bugfix release, it should support loading SREC files again. The only long-term solution is to make ePython use ELF files instead.

Thanks for the report, I have updated ePython to additionally build an ELF device executable and default to loading this ELF version rather than the SREC so that should fix the issue.

Cheers,
Nick

I'm having some trouble getting the first hello world example to run properly. I've checked that the environment variables are configured correctly and that I haven't made any typo's. Also chmod'd the file to make it executable, although I don't think that's necessary. Here's the error I get:

root@parallella:~/epython# epython hello.py
/usr/bin/epython: line 28: 18620 Bus error $FILE "$@"

The bus number changes each time I execute it. Any ideas?

Thank you for writing a great intro to the Epiphany!

Hi - sorry to hear you are having issues, I guess this is a "normal" 16 core Epiphany chip? Which image are you using, are you using the latest (March) one? Can you run other (non-ePython) examples OK on your Parallella?

Yes, I just purchased the 16-core Parallela Micro-server off Amazon this week. I'm using the latest headless image of Ubuntu. I actually haven't attempted any other examples yet, but was planning on it. Do you have any recommendations? I'll start looking
