Re: [OMPI users] "Warning :: opal_list_remove_item" with openmpi-2.1.0rc4

Roland, the easiest way is to use an external hwloc that is configured with --disable-nvml an other option is to hack the embedded hwloc configure.m4 and pass --disable-nvml to the embedded hwloc configure. note this requires you run autogen.sh and you hence needs recent autotools. i guess Open

Hi Akshay, Would it possible for you to provide the source to reproduce the issue? Yes, I've appended the file. Kind regards Siegmar Thanks On Tue, Mar 21, 2017 at 9:52 AM, Sylvain Jeaugey > wrote: Hi Siegmar, I think this

If you installed CUDA libraries and includes in /usr, then it's not surprising hwloc finds them even without defining CFLAGS. I'm just saying I think you won't get the error message if Open MPI finds CUDA but hwloc does not. On 03/21/2017 11:05 AM, Roland Fehrenbacher wrote: "SJ" == Sylvain

Re: [OMPI users] "Warning :: opal_list_remove_item" with openmpi-2.1.0rc4

Hi Siegmar, I think this "NVIDIA : ..." error message comes from the fact that you add CUDA includes in the C*FLAGS. If you just use --with-cuda, Open MPI will compile with CUDA support, but hwloc will not find CUDA and that will be fine. However, setting CUDA in CFLAGS will make hwloc find

Hi, I have installed openmpi-2.1.0rc4 on my "SUSE Linux Enterprise Server 12.2 (x86_64)" with Sun C 5.14 and gcc-6.3.0. Sometimes I get once more a warning about a missing item for one of my small programs (it doesn't matter if I use my cc or gcc version). My gcc version also displays the
