I'm not using Hydra; just the "distributed builds" feature of regular Nix, with the twist that the nodes have a shared filesystem where the store lives. Perhaps Hydra also works this way, but I know nothing about it. I still trigger individual builds manually with nix-env and so forth. > What kind of hardware are you using and how many machines are you running? It's a research cluster at UC Berkeley. So far I'm only using a small fraction of it, but in total there are about 268 nodes (8 cores, 24GB each) with Nehalem processors and Infiniband interconnect. > I know you've only just got it to work but will you be able to post > any statistics in the future, say for instance how long it takes to > build the desktop CD?

Unfortunately not... it's a shared resource so it wouldn't be appropriate for me to run this kind of benchmark. > Are you writing a paper on it or is it just for fun? I've repurposed Nix to manage data analysis workflows, in this case for bioinformatics computations. I do plan to write up my whole infrastructure around that at some point, but first I have to finish my dissertation (biology, not CS) :) -ds _______________________________________________________ David Soergel (650) 303-5324 [email protected] http://www.davidsoergel.com _______________________________________________________ _______________________________________________ nix-dev mailing list [email protected] https://mail.cs.uu.nl/mailman/listinfo/nix-dev
