Hopper (Cray XE6) (for v1.8 and later) +------------------------- + +2.5.1 Building HDF5 for Hopper +------------------------------------------ +The following steps are for building HDF5 for the Hopper compute +nodes. They would probably work for other Cray XE6 systems but have +not been verified. + +Obtain a copy from the HDF ftp server: +http://www.hdfgroup.org/ftp/HDF5/current/src/ +(link might change, so always double check the HDF group website). + +$ wget http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-x.x.x.tar.gz + +unpack the tarball + +$ cd hdf5-x.x.x/ +$ CC=cc FC=ftn ./configure \ +--prefix=/project/hdf5/hdf5 --enable-parallel --enable-fortran \ +--disable-shared --disable-production +$ make + +Run make check. make check should be run on the compute nodes, not the +front end nodes. So using a PBS batch script, allocate 4 or more +cores. Always consult with the machine's website on how to create PBS +scripts and allocate nodes for your job. For Hopper, all the +information can be found on: +http://www.nersc.gov/systems/hopper-cray-xe6/ + +save the PBS script into your HDF5 build directory.
