That disclaimer about the code means that you can in fact compile Chimera from the provided source, but the result will not be able to compute/show molecular surfaces or any attributes based on such calculations (such as solvent-exposed surface area). Depending on why you need Chimera on Summit, this may or may not be good enough. The other disclaimer in the code about getting the compile to work being challenging is absolutely true, so that should be taken into account when deciding what course of action you want to take from here.</div><div><span class="gmail-m_7835092081312335076Apple-tab-span" style="white-space:pre-wrap"> </span>Another option to consider is compiling ChimeraX on Summit instead. Again, since I don’t know your motivation I can’t say if ChimeraX’s current capabilities would meet your needs, but it seemed like something worth mentioning.</div><div><br></div><div>—Eric<br><div><br><blockquote type="cite"><div>On Jan 18, 2019, at 8:31 AM, Victor Padilla-Sanchez <<a href="mailto:70padillasan@cua.edu" target="_blank">70padillasan@cua.edu</a>> wrote:</div><br class="gmail-m_7835092081312335076Apple-interchange-newline"><div><div dir="ltr">Hi Eric,<div><br></div><div>The engineer at Oak Ridge says Summit architecture is incompatible:</div><div><br></div><div><span style="color:rgb(80,0,80)">SummitDev is based on the PowerPC (ppc64le) architecture, and is binary</span><br style="color:rgb(80,0,80)"><span style="color:rgb(80,0,80)"> incompatible with Chimera as it's distributed.
