::pwtk::serial_prefix

SYNOPSIS

proc ::pwtk::serial_prefix {args} {

PURPOSE

Set or query the serial_prefix for the serial execution of programs. In serial mode programs are run as: 

     $serial_prefix program.x

Another example where this options needs to be used is when using QE executables from the container. For example the following instructs PWTK how to run serial code from the singularity container: 

    serial_prefix "singularity exec /path/to/qe-6.7.simg"

where /path/to/qe-6.7.simg is the singularity container image.

RETURN VALUE

The value of the serial_prefix.
