Hi,<br>
<br>
I had Cuda v4.1 installed because OpenMM was compatible with that version. I removed it and installed successfully Cuda v4.2 (the latest production release) and Cuda SDK v.4.2.<br>
<br>
I then recompiled FFTW using different combinations of configure flags bust still no luck. Could you please provide a recommended configure command line for a 86_64 Linux laptop and the respective cmake options to compile GROMACS? I would greatly appreciate
that.<br></div></blockquote><div><br></div><div>Please try </div><div>cmake -DGMX_ACCELERATION=SSE4.1</div><div>and if that doesn't work</div><div>...=SSE2</div><div><br></div><div>If you could provide us more information of why your gcc doesn't understand -mavx that would be useful. Is gcc really 4.7 as cmake prints? Gcc 4.7 should support 4.7 thus this is confusing. How did you obtain gcc? Is it from your distribution (if so which one) or did you download and compile gcc yourself? If so how?</div>
