Thank you for all your answers.
Our nodes does have internet access, so it won't be a problem.
Il will recreate all the modules next week using the wonderful 2.8.1
version and the eb --job test.

Laurent

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.

Dear Easybuild users,
first I would like to thank all developpers for this great tool
that helps us a lot in installing software on the new cluster we
bought.
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.
Best regards,
