Hi Mark, thank you for your reply. I inspected CMakeError.log and CMakeOutputlog: though several errors were reported in the first one, no mention to GmxDetectCpu at all. When trying "cmake --debug-trycompile $builddir -UCPU_DETECTION_COMPILED", the output is: "debug trycompile on -- The

Hi, In that case, I would look at $builddir/CMakeFiles/CMakeError.log (and maybe $builddir/CMakeFiles/CMakeOutput.log) to see what was reported about that attempted compilation of GmxDetectCpu program. Depending what is learned, you might want to try your usual cmake call, and then cmake

Hi Mark, actually running cmake in the output I can read "Did not detect build CPU vendor - detection program did not compile". Any suggestions about the origin of the issue and possible solutions? Thanks Stefano

Hi, There will have been reports by cmake about whether the detection program compiled and/or ran successfully, which would be useful diagnostic information. Please run cmake in a fresh build directory and look for that. It is possible to run that program individually, if the issue is that it

I cannot say about BIOS/firmware yet, I made a quite "standard" installation of centOS 7, but I'll try to check; as for cpu, for what it means, I made the stress test which brought up temperature for two hours together with gpu_burn, so I would exclude cooling failure. A further update: I

Hi Szilard, thanks for your reply. The compiler is gcc 4.8.5. I put below the link where you can find the files coming from cmake and the output for "AUTO" SIMD instruction. As for cpu only, as you had suggested previously I tried a run (after compiling with AVX2_256) and it worked without any
