Revision as of 19:53, 19 September 2018
Background
The operating system on Abel dates back to the original year of installation (2012, for all we recall). While many development tools and libraries are available in newer versions (through the module system), the version of the basic GNU C Library is intricately linked to the Linux kernel. Some packages that are distributed in pre-compiled form (typically as Python wheels) require more recent versions of the C Library. A little bit of trickery makes it possible to get these binaries to execute on Abel, using a custom, NLPL-specific installation of the GNU C Library and its dynamic linker.
Installation
wget https://ftp.gnu.org/gnu/glibc/glibc-2.18.tar.bz2 tar jpSxf glibc-2.18.tar.bz2 cd glibc-2.18 mkdir build cd build module purge module load gcc/4.9.2 cuda/8.0 ../configure --prefix=/projects/nlpl/software/glibc/2.18 make -j 8 make install make localedata/install-locales ln -s /usr/share/zoneinfo/Europe/Oslo /projects/nlpl/software/glibc/2.18/etc/localtime
To pre-configure the custom dynamic linker, allowing it to make use of ‘standard’ library locations that need not be on $LD_LIBRARY_PATH. In mid-September 2018, at least, basic CUDA libraries appear to be installed into /usr/lib64/, but only on GPU-enabled compute nodes.
