Could you or someone else build FEniCS with fenics-install.sh (takes time but is presumably automatic) and compare?
The alternative would be for me to build FEniCS manually but that takes a lot of manual effort and it's not clear I can make a "good" build. It would be good to get a number, not only to check for a possible regression but also to test whether something is suboptimal in the HashDist build. Johannes, is the HashDist build with optimization? -- Anders mån 30 mars 2015 kl 17:05 skrev Garth N.
