We would like to know others thoughts on this.<br></div><div>In EC, we have been doing CPU intensive computations to encode and decode data before writing and reading. This requires a lot of CPU cycles and we have<br></div><div>been observing 100% CPU usage on client side. Data healing will also have the same impact as it also needs to do read-decode-encode-write cycle. </div><div>As most of the modern servers comes with GPU feature, having glusterfs GPU ready might give us performance improvements.<br></div><div>This is not only specific to EC volume, there are other features which will require a lot of computations and could use this capability; For Example:<br></div><div>1 - Encryption/Decryption<br></div><div>2 - Compression and de-duplication<br></div><div>3 - Hashing<br></div><div>4 - Any other? [Please add if you have something in mind]<br></div><div><br></div><div>Before proceeding further we would like to have your inputs on this.</div><div>Do you have any other use case (existing or future) which could perform better on GPU?<br></div><div>Do you think that it is worth to integrate GPU with glusterfs? The effort to have this performance gain could be achieved by some other better ways.<br></div><div>Any input on the way we should implement it.<br></div><div><br></div><div>There is a gihub issue opened for this. Please provide your comment or reply to this mail.<br></div><div><br></div><div>A - <a href="https://github.com/gluster/glusterfs/issues/388">https://github.com/gluster/glusterfs/issues/388</a> <br></div><div><br></div><div>---<br></div><div>Ashish<br></div></div></body></html>
