::pwtk::pseudo::etot_test_many

SYNOPSIS

proc ::pwtk::pseudo::etot_test_many {args} {

USAGE

   ::pwtk::pseudo::etot_test_many ?OPTIONS? ppFileList

DESCRIPTION

Perform the ::pwtk::pseudo::etot_test pseuo-potential test for many pseudopotentials.

In most case no options are needed, hence use options only if the default setup fails.

For each pseudopotential, the calculations will be performed in a separate subdirectory. The subdirectory name is derived from the name of pseudopotential by stripping the ".UPF" extension and adding the ".d" postfix ("d" standing for directory. For example: 

      pseudopotential:  O.pbe-n-kjpaw_psl.1.0.0.UPF
      subdirectory:     O.pbe-n-kjpaw_psl.1.0.0.d/

whereas for old naming: 

      pseudopotential:  AgUSPBE.RRKJ3
      subdirectory:     AgUSPBE.RRKJ3.d/

OPTIONS

Options are the same as for ::pwtk::pseudo::etot_test

ARGUMENT

RETURN VALUE

The hardest ecutwfc and ecutrho values among the tested pseudopotentials, as the "$ecutrho $ecutwfc" list.
