mpicc is a symlink pointing to ompi_wrapper_script I guess we do not correctly support the --target option, unless you changed your configure options meanwhile, so you have to manually update the broken symlinks so they point to arm-openwrt-linux-muslgnueabi-ompi_wrapper_script Cheers, Gilles

Re: [OMPI users] communications groups

2016-10-18 Thread Gilles Gouaillardet
Rick, if you look at the big picture, i think 3 communicators make more sense. now keep in mind that a given task is only part of two valid communicators. depending on how you implement communicator creation, there could be 2 communicators per task, or 3 communicators, and one is MPI_COMM_NULL.

Hi George and Jeff, Thank you for taking the time to respond to my query. You did inspire me in the right direction. Some of the variables involved in the calculation of B were not broadcast. In addition, a double do-loop combined with an IF statement was overwriting on the correct B values.

After looking into this a bit more it appears that the issue is I am building on a head node which does not have the driver installed. Building on back node resolves this issue. In CUDA 8.0 the NVML stubs can be found in the toolkit at the following path: ${CUDA_HOME}/lib64/stubs For 8.0
