Hello Kenneth, it will be great to have you there!
I am aware of that paper since it was presented at Reppar15 this year (at EuroPar15) where we also had a paper (their presentation was right before our one) and yes I agree they did not fully get the power of EasyBuild, anyway we had a nice conversation with these guys that day. I told my supervisor about your BoF, hope he can pass by.

Besides the things mentioned by Alan below, to have a truly reproducible setup, EasyBuild should be combined with Nix (see https://nixos.org/nix/), in order to be in full control of the build environment. Here's a very interesting paper on the use of Nix in an HPC context: http://arxiv.org/pdf/1506.02822.pdf . They discuss some of the shortcomings EasyBuild has w.r.t. reproducibility, and they do a good job at it. I feel they're not fully grasping the power of EasyBuild, but I can forgive them, I really like the paper. I hope to get them to submit a talk to the HPC & Big Data devroom at FOSDEM'16 I'm co-organizing (see http://hpc-bigdata-fosdem16.github.io<http://hpc-bigdata-fosdem16.github.io/>). And since we're on the topic of BoF sessions at SC15, here's a link to our own "Getting Scientific Software Installed" BoF (Tue Nov 17th, 12.15pm): http://sc15.supercomputing.org/schedule/event_detail?evid=bof113 . Tell your colleagues to join us there, and bring up the topic of reproducible builds. I'll be happy to let them advertise their BoF which is shortly after ours. regards, Kenneth On 10/11/15 19:07, Alan O'Cais wrote: Hey Danilo, I won't be at SC but this topic is something that interests me. As EasyBuild develops, some features make reproducability better (like becoming as independent from the system compiler as possible) while others are introducing potential unknowns (--include-easyblocks, --include-toolchains, --minimal-toolchains). I've already been thinking about making a PR that attempts to improve reproducability by including the toolchain and easyblock classes (*that were actually used* when producing the build) in the easybuild directory of the installation along with the easyconfig of the installation that already exists there. I think with some tweaking and a few more features this could be very useful.

I exploit this mailing list to sponsor a BOF organised by the group, High Performance and Web Computing of the University of Basel, where I am a PhD candidate. We are developing a tool targeting reproducibility in computational sciences, allowing collaboration between users. During the last SC I discovered EasyBuild and lately decided to rely on it for getting “reproducible builds”. That’s why we are integrating it as a basis for our tool “PROVA!”. I won’t be at SC this year but my supervisor, prof. H. Burkhart, is organising the BOF in collaboration with prof. G.Wellein from FAU-Erlangen. It will be a good occasion for talking of the difficulties for reproducible research.
