bindmem [ 0 1 ] [nodes]

Set flag marking if this nodes will use memory-binding as NUMA policy. Relevant values are 'false', 'true', 'no', 'yes', 0 or different from 0.

cpumap map [nodes]

Set the map used to assign CPU-slots to physical cores to map. Map is a quoted string containing a space-separated permutation of the number 0 to Ncore-1. Here Ncore is the number of physical cores available on this node. The number of cores within a distinct node may be determined via 'list hw'. The first number inmap is the number of the physical core the first CPU-slot will be mapped to, and so on.

supplementaryGroups [ 0 1 ] [nodes]

The supplementaryGroups flag defines whether a process spawned should belong to all groups (true) defined for this user or only to the primary group (false). Relevant values are 'false', 'true', 'no', 'yes', 0 or different from 0.

statusBroadcasts [ num ] [nodes]

Set the maximum number of status broadcasts initiated by lost connections to other daemons. See also parastation.conf(5).

rdpTimeout [ ms ] [nodes]

Set the RDP timeout in ms for all selected nodes. See also parastation.conf(5).

deadLimit [ num ] [nodes]

Set the dead-limit of the RDP status module. After this number of consecutively missing RDP- pings, the master declares the node to be dead. Only relevant, if MCast is *not* used. See also parastation.conf(5).

statusTimeout [ ms ] [nodes]

Set the Timeout of the RDP status module. After this number of milli-seconds a RDP-ping is sent to the master daemon. Additionally, the master daemon checks for received ping-messages. Only relevant, if MCast is *not* used. See also parastation.conf(5).

rdpClosedTimeout [ ms ] [nodes]

Set the RDP closed timeout of the RDP status module. See also parastation.conf(5).

rdpResendTimeout [ ms ] [nodes]

Set the RDP resend timeout of the RDP status module. See also parastation.conf(5).

rdpMaxACKPend [ num ] [nodes]

Set the maximum number of pending ACKs within the RDP facility. See also parastation.conf(5).

shutdown [nodes]

Shutdown the ParaStation daemon on all selected node(s). As a consequence all processes using the selected node(s) are killed!

test [ quiet normal verbose ]

All communications links in a ParaStation network are tested.
