<div dir="ltr"><div><div><div>Hi Richard/Barry,<br><br></div>I don't have any particular need just yet, but since most HPC clusters have Intel CPUs, I think an Intel Sparse MKL PETSc branch would bring immediate optimisations. I do realise that it does require quite a bit of work as Intel probably didn't design the API that well and which will require some re-factoring. I'm CC'ing Gennady from Intel whom I spoke to about this. Perhaps the MKL branch work can be coordinated with him.<br><br></div>Regards,<br></div>Wadud.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On 18 December 2015 at 19:50, Richard Mills <span dir="ltr"><<a href="mailto:richardtmills@gmail.com" target="_blank">richardtmills@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>Hi Wadud,<br><br></div>I work at Intel and plan to add support for
