HOSTNAME — User Commands

NAME

hostname − Print name or sprite ID of host

SYNOPSIS

hostname [−v] [−p] [−i] [−type]

OPTIONS

−vPrint out information about the virtual host, which is the host on which the process is executing if it is not migrated, or the process’s home node if it is migrated. This is the default.

−pPrint out information about the physical host, which is the host on which the process is physically executing, regardless of whether it is migrated.

−iPrint out sprite ID instead of host name.

−type
Print out the machine type.

DESCRIPTION

By default, hostname prints out the official name of the host on which the process “appears” to be executing, as specified in the host description file. (This is equivalent to the −v, or virtual host, option.) Other options may be used to specify that information about the host on which the process is currently physically executing be printed, or that the integer sprite ID of the host is to be printed instead of host name.
