I'm not sure what SIMD means yet, but I'll figure it out ;-). I tend to favor fecpp because it is more self contained and may be easier to embed than https://pypi.python.org/pypi/zfec >> >> Cheers >> >> -- >> Loïc Dachary, Artisan Logiciel Libre >> > > > Having played with zfec (more the underlying fec.[c,h] file) it's well written and self-contained as I remember it; but you will need to write a bunch of wrapper functions to chunk up data and pad out blocks and of course turn it into a library before you can use the underlying zfec implementation for ceph. If my memory is right, zfec's c code requires a C90 or C99 compiler to build it, I'm not sure if you care about that. Hi Jimmy, fecpp and zfec compile and run using g++ 4.7 . The requirements for http://code.google.com/p/holostor/ may be different but I suspect it also works.
