How do I set maxtasks during regtest?

[Nico Holmberg]

Hi,

The number of tasks and other settings can be defined in a configuration 
file, which is passed to the regtest script with the -c flag (see 
./do_regtest -h). You can find example configuration files in the folder 
cp2k/tools/regtesting/regtest_conf. 

For example, to use 4 tasks in total and 2 tasks per test (popt binary), 
you can set

numprocs=2
numthreads=1
maxtasks=4

You should also comment out the line "maxtasks=$(nproc --all)" if you are 
using one of the example configurations files as a template.


BR,

Nico
