There is a caveat to building on the nodes themselves, some software actually requires internet access at build time, so not everything will work that way. The amount of software that requires this is not large...and if your nodes are connected to the internet you don't have a problem.

Thanks! I should really look into a "happy EB users" page in the documentation, or maybe a corner on the website... I have some issue with OpenMPI modules which may be related to the fact that we compile in a virtual machine, which has a virtual mellanox interface, and we execute the code on nodes that have a Qlogic interface. This two cards does not use the same MPI communication layer. I would like to now what it the solution for building optimised modules : - configure easybuild to force compilation options (e.g. optarch=HASWELL, ...) - use eb --job with our Slurm scheduler - reserve a node independently and build the module in a sbatch script I would strongly recommend to build on the actual workernodes themselves. Although you may get a long way with more generic compilation options via --optarch=GENERIC (--optarch=HASWELL wouldn't work, since GENERIC is a keyword and any other value is treated as the name of a flag, so you'd end up with "gcc -HASWELL"). We use --job all the time, and it works really well, especially since it also parallelizes the installations. We use easybuild 2.6.0 This is EasyBuild 2.6.0 (framework: 2.6.0, easyblocks: 2.6.0) I would recommend upgrading to the latest & greatest v2.8.1, which should be fully backwards compatible. regards, Kenneth We use the following toolchains : - intel2015a - foss2015a - iompi-2015.03 Thank you for any help.
