Yes, that seems to be the problem. I minimized the configuration using Conjugated Gradient and everything looks right now. Thank you again! -- View this message in context: http://gromacs.5086.n6.nabble.com/Potential-energy-from-a-previous-configuration-mismatch-tp5003352p5003432.html Sent

Hi, I think this happens either because you have cmake 2.8.10 and the host-compiler gets double-set or because something gets messed up when you use clang/clang++ with gcc as the CUDA host-compiler. Could you provide the exact error output you are getting as well as cmake invocation? As I don't

the most efficient way is just give up a macOS and switch to a more reasonable OS like Linux. macOS is definitely a pain in the neck , and it is completely nightmare to use it for computational work. On 12/03/2012 04:10 PM, Szilárd Páll wrote: On Fri, Nov 30, 2012 at 11:01 AM, Carlo

Hi, Preferably we should avoid starting an OS flame-war here. However, before this thread turns into an ode to Apple, I have to say: Mac OS X is/can be a pain both for development and computational use. As long as you use it to code for iPhone or write some Mac app in Xcode, it's probably

Looks like a compiler bug to me, and google agrees http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47318. Even if there were not this bug, we would strongly encourage you to get the better performance available from more recent versions of gcc. I was about to suggest 4.6 or newer, but the above URL

Hi, a small addition to Mark's answer. If you want/need to use an older gcc version 4.4.6 and 4.5.3 have the necessary fix too. Also you can disable AVX with cmake -DGMX_CPU_ACCELERATION=SSE4.1 . But you will get somewhat lower performance (AFAIK only 10% with group kernels but more with verlet
