Hi Loic,

Thank you for your advices.
We have uploaded our latest codes to the following folk repository for an early review.

https://github.com/miyamae-takeshi/multiple-shec

SHEC is located in src/erasure-code/shec directory.

We are verifying SHEC's advantages on our Ceph cluster. It takes a little bit more.
Would you please start the review before that?

Best regards,
Takeshi Miyamae

The work you have done is quite impressive :-)

Although we're late in the Hammer roadmap, it's a good time for an early preview. It will help show what needs to be changed to accomodate the SHEC plugin.
