Ordering issue on occigen
There is an issue into the ordering of pastix on the occigen cluster when launching the simple example on a laplacian.
Pastix has been installed with both scotch 6.0.4 and 5.1.10b, with mkl and intel compiler 17.0.0.
The simple example with a 1D laplacian (e.g. ./simple --lap 100 -t 4) is fine.
However, when considering a 2D laplacian (e.g. ./simple --lap 100:100 -t 4), the run gets stuck into the ordering step of pastix, more precisely into scotch. See this ddt screenshot for more details:
A similar behavior has been observed when attempting to use pastix into maphys on occigen on maphys' classical examples.
