[reported by blelbach] [Trac time Wed Aug 17 17:54:07 2011] This is a meta-ticket for the next generation of HPX distributed launches (e.g. the replacement for hpx_pbs.py/hpx_run.py).

[comment by hkaiser] [Trac time Mon Aug 29 19:19:55 2011] Direct support for PBS has been added. All HPX applications now evaluate the PBS_NODEFILE, PBS_NODENUM and PBS_NUM_PPN environment variables to deduce information about the distribution configuration of the application.

In addition the command line parameters --nodefile and --nodes have been added to allow to directly specify the node file or the list of nodes.

For local runs, the command line options -1, -2, ... -N have been added, which allow seemless startup of distributed runs on single nodes.

The hpx_run.py/hpx_pbs.py scripts still need to be adapted to use the new command line options.
