Hi al,
I have installed Dealii 9.4.2 using "spack install dealii" on Ubuntu 20.04
inside WSL. When I try to mpirun step-17 and step-18 I either encounter an
error message (attached at the end) when the number of cores is more than
two or for two cores the memory consumption is huge. In my case, the entire
48 gb of my laptop is getting used.
>From the online discussions, I gather this is because of METIS
installation. How do I fix it?
Regard,
Ananya
