mSHEC r33 release

mSHEC r33 release

[Miyamae, Takeshi]

Hi Loic,

We have released mSHEC r33 just now.

https://github.com/t-miyamae/ceph

NOTABLE CHANGES
  - ensure thread safety
  - support generator matrix cache (added ErasureCodeShecTableCache.cc)
  - refer to the shared jerasure 2.0 library
  - improve verification of return code in test codes
  - add test code for verifying thread safety (added TestErasureCodeShec_thread.cc)

LIMITATION
  - There are still lots of minor problems in test codes.
    We will fix it by 1/26(mon).

Best regards,
Takeshi Miyamae

Thanks, I'll take a look. Could you please create a pull request against the master branch ? When you do so, it will be convenient if you submit from a branch that has a descriptive name such as wip-mSHEC or something similar.

Cheers

Hi,

Since the SHEC plugin depends on the jerasure plugin, it would be simpler if it loaded it instead of including it. The main problem with the current inclusion is that it does not compile any SIMD acceleration code and loses the benefit of optimization when the CPU can provide it. 

There are two ways out of this 

a) add to the SHEC plugin the same selection that jerasure has (in the Makefile and with something like http://workbench.dachary.org/ceph/ceph/blob/master/src/erasure-code/jerasure/ErasureCodePluginSelectJerasure.cc

b) compile jerasure as a convenience library that can be included by both the jerasure and SHEC plugin.

The LRC plugin loads the jerasure plugin but the SHEC plugin cannot do the same because the standard API at http://workbench.dachary.org/ceph/ceph/blob/master/src/erasure-code/ErasureCodeInterface.h is not enough.

Note that this is not a blocker for the inclusion of the plugin and can be done afterwards.

Cheers

Hi,

I see the following error when running make check http://paste2.org/dNChVpL1 . Does it ring a bell ?

RE: mSHEC r33 release

[Miyamae, Takeshi]

Hi Loic,

Thank you for your advice and information.
Both approaches are attractive and we have started to consider which one to take.
However, I'm afraid that we might not have enough time to implement and test it
until the first release of Hammer.

Best regards,
Takeshi Miyamae

Hi Loic,

I have created a pull request of wip-mSHEC.

wip-mSHEC pull request #3484
https://github.com/ceph/ceph/pull/3484

Besides, we changed the name of our fork repository.
https://github.com/t-miyamae/wip-mSHEC

I'm not sure that it was done correctly because I am a beginner.
Would you check it, please?

Best regards,
Takeshi Miyamae

It looks like the branch from which you created the pull request still is master and not wip-mSHEC. That's not a problem. It only really becomes a problem if you have more than one pull request going on.

I'm sorry that I didn't have such a common sense.
We recreated the pull request from wip-mSHEC branch.

wip-mSHEC : multiple Shingled Erasure Code #3488
https://github.com/ceph/ceph/pull/3488

Could you change the branch you will pull from?
If it were difficult or not good for the reason of logging comment already written, pulling from master branch would also be OK for us and I would remove the latter pull request.

Takeshi Miyamae

Hi Loic

> We recreated the pull request from wip-mSHEC branch.

I'm sorry. I had thought twice and judged it would not be better to change the branch.
I'd close our 2nd pull request and delete wip-mSHEC branch.

Only #3484 is alive as our mSHEC pull request at this moment.

wip-mSHEC : multiple Shingled Erasure Code #3484
https://github.com/ceph/ceph/pull/3484
