Hi,
I downloaded a 30 day trial to try out the new 2019. Currently, I'm using version_info.c as a test case, which is from the Intel webpage:
https://software.intel.com/en-us/articles/using-intelr-mpi-library-50-wi...
Is there an "environmental variable" that I can export or something else I can set to suppress the warnings like "I_MPI_HYDRA_UUID environment variable is not supported" as shown below in Update 4 so that it has output without those messages like Update 2? I experienced a memory error (i.e. core dump) similar to the segmentation fault reported for non-legacy mpiexec.hydra in the post at:
https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technolog...
Thanks,
Gavin
