5th easybuild hackathon meeting minutes day 2

5th easybuild hackathon - notes day 1 - notes day 3

Markus: implementing a custom module naming scheme for a hierarchical scheme

• currently missing in EasyBuild:
• prepend to $MODULEPATH in generated compiler/mpi modules should be automagic
• provide full parsed easyconfig file to module naming scheme module, so e.g. module class is accessible (see related framework issue)
• need to provide %(modulesroot)s, allow specifying absolute paths via modextrapaths (prepend_paths)
• generated modules use full module names, while they should only use the module names relative to the $MODULEPATH in a hierarchical setup...
• see also https://github.com/hpcugent/easybuild-framework/issues/862

Pavel: testing build of new Cube version with EB (using system provided deps)

• plan is to create easyconfig files and store them in own repository, then issue pull request shortly before release
• Cube silently enforces --disable-gui if the provided Qt dependency is not OK (configure doesn't complain)
• missing in EasyBuild:
• SystemModule easy block?
• support in --robot for specifying URLs to remote easyconfig repos

Christian: write easyblock for installing Score-P dev tools in the same prefix (libtool, autoconf, …) after patching them

• issues with setting up 'production' and 'development' environments for writing own easyblocks/easyconfigs

Marc: install gmpich2 based on existing gcc/mpich3 modules, build FFTW on top of that

• missing in EasyBuild
• documentation or cmdline option on generating module for system-provided tools or existing modules

Inge: imkl testing tool with static build, building and installing ELPA

• figure out problem with imkl include files not being found => add -I$EBROOTIMKL/mkl/include/intel64/lp64 to $FCFLAGS

• fix BLAS linking issues by defining $LIBS => makes sure that libraries are added at the end, which is a strict requirement when statically linking (cfr. http://software.intel.com/en-us/articles/static-linking-with-mkl-ipp-or-tbb-may-give-unresolved-references)

• building of examples is broken due to use of -ldl ?!?

Alan: look into multi-user setup

• properly set umask
• set sticky bit on top install directory

Bernd: plans to flesh out easyblock for Tau, and also look into HPC Toolkit (dep for PerfExpert)

• lots of documentation available at JSC (Anke) on building perf tools (like HPC Toolkit)

discussions

• hierarchical modules
• multi-user usage
• get software installed via JSC policies (no write access to shared FS, now using an old packaging system)
• different groups look after different tools (compiler, math libs, IO libs, …), have to be provided to each other
