Cyril would know better but he's currently on vacation. I don't think the required scotch release is already officially publicly available online.
I am not sure what problem you're trying to solve here. This feature isn't really useful if you only have two nodes. It was rather designed for process placement on large clusters (by the way, you'll need something to build a communication pattern of your MPI application as a communication matrix). Regarding configure, once the right scotch release is installed, there's no configure options if I remember correctly, you just need to point your compiler to scotch include and lib directories. Something like this may help: export C_INCLUDE_PATH=/opt/scotch-6/include export LD_LIBRARY_PATH=/opt/scotch-6/lib export LIBRARY_PATH=/opt/scotch-6/lib Brice Le 22/02/2017 13:38, Михаил Халилов a écrit : > I tried to configure hwloc with scotch, but I still haven't success > with that case.
