<div dir="ltr"><div>Hi Bishwajit,<br><br></div>I hate to be the bearer of bad news, but the K20c was a specific model of Tesla that is restricted to compute functionality only and is not capable of performing OpenGL functions via EGL. As such, it won't be usable by ParaView for rendering. Almost all other Teslas, including the other K20 models (K20m and K20x), can be switched into either compute-only, graphics-only, or both modes, but the K20c only has compute mode available. So even though you may get it building with the libraries in the folder Andy is pointing to, I don't believe you'll actually get a working EGL device. If you do, then fantastic, but don't get your hopes up :-/<br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div>- Chuck<br></div></div></div></div></div></div></div>
