Dear all:

I’m trying to use parallel hdf5 on KNL nodes (interactive mode), but having some trouble. I’m able to compile my code (using libraries at /soft/libraries/knl/lib) but when I run the application I get segmentation fault. I get similar result with h5dump (KNL version): [bicer@knl06 ~]$ /soft/libraries/knl/bin/h5dump -H /home/bicer/data/hornby_1_x1.h5 Segmentation fault

I tried to compile parallel hdf5 from scratch but configuration fails while compiling a simple MPI-IO code: [bicer@knl06 hdf5-1.10.0-patch1]$ CC=/soft/compilers/intel/compilers_and_libraries_2017.2.174/linux/mpi/intel64/bin/mpiicpc ./configure --enable-parallel --prefix=/home/bicer/local/knl … checking for parallel support files... provided by compiler checking whether a simple MPI-IO C program can be linked... no configure: error: unable to link a simple MPI-IO C program

Has anyone used parallel hdf5 on KNL before? I would appreciate any help on this.

Regards, Tekin
