Steve, I have no further good ideas. You could try simplifying your compile options to see if that will help produce a runnable binary. The KNL should support AVX but maybe the first thing to try is removing all the AVX flags. If that works, you can try adding -xMIC-AVX512. kevin >Well further tests have to wait until Monday now, but > >1) I used both mcmodel=medium and large -- both fail the same way >2) It runs on blues (haswell nodes and Intell 11 compiler) with mcmodel=medium >3) I forget the number of OMP threads I was using -- I think 32. >4) The size command does not show a huge executable (the big stuff will come > later from allocates): >>>>> text data bss dec hex filename >>>>> 2459352 124772 24979752 27563876 1a49764 x.testwf.4he-pn <<<< this works >>>>> 2192689 92004 623277384 625562077 254951dd x.testwf.12c-11_states-pn <<< this fails > >Steve > >Steven C.

Re: [JLSE-Intel-NDA] Help on knl00 segfault

I would say it has something to do with the memory model and the limitations that the large segments of the code cannot be correctly located by the OS. The problems shows up at the first executable statement. Two suggestions: try to set the number of OMP threads to some small number (4 or 8 to start with), and try -mcmodel large.

Re: [JLSE-Intel-NDA] Help on knl00 segfault

I'm not sure what you mean. random2.f is written in standard fortran 90. However the error doesn't seem to have anything to do with random2.f per se. I commented that line out and now the traceback points to the next non-comment line. So I think the segfault is happening at load time and the traceback just points to the first non comment line. I have to go now; I guess this will have to wait until next week. Thanks, Steve Steven C.
