slurm::hostlist
Slurm::Hostlist(3pm) User Contributed Perl Documentation Slurm::Hostlist(3pm)NAME
Slurm::Hostlist - Hostlist functions in libslurm
SYNOPSIS
use Slurm;
$hostnames = "node1,node[2-5,12]";
$hl = Slurm::Hostlist::create($hostnames);
$cnt = $hl->count;
$hl->push("node21,node[27-34]");
while($host = $hl->shift()) {
print $host, "
";
}
print $hl->ranged_string(), "
";
DESCRIPTION
The Slurm::Hostlist class is a wrapper of the hostlist functions in libslurm. This package is loaded and bootstrapped with package Slurm.
METHODS
$hl = Slurm::Hostlist::new($str);
Create a new hostlist from a string representation. Returns an opaque hostlist object. This is a CLASS METHOD.
The string representation ($str) may contain one or more hostnames or bracketed hostlists separated by either `,' or whitespace. A
bracketed hostlist is denoted by a common prefix followed by a list of numeric ranges contained within brackets: e.g. "tux[0-5,12,20-25]".
To support systems with 3-D topography, a rectangular prism may be described using two three digit numbers separated by "x": e.g.
"bgl[123x456]". This selects all nodes between 1 and 4 inclusive in the first dimension, between 2 and 5 in the second, and between 3 and 6
in the third dimension for a total of 4*4*4=64 nodes.
If $str is omitted, and empty hostlist is created and returned.
$cnt = $hl->count();
Return the number of hosts in the hostlist.
$pos = $hl->find($hostname);
Searches hostlist $hl for the first host matching $hostname and returns position in list if found.
Returns -1 if host is not found.
$cnt = $hl->push($hosts);
Push a string representation of hostnames onto a hostlist. The $hosts argument may take the same form as in create().
Returns the number of hostnames inserted into the list,
$cnt = $hl->push_host($hostname);
Push a single host onto the hostlist hl.
This function is more efficient than slurm_hostlist_push() for a single hostname, since the argument does not need to be checked for
ranges.
Return value is 1 for success, 0 for failure.
$str = $hl->ranged_string();
Return the string representation of the hostlist $hl. ranged_string() will write a bracketed hostlist representation where possible.
$host = $hl->shift();
Returns the string representation of the first host in the hostlist or `undef' if the hostlist is empty or there was an error allocating
memory. The host is removed from the hostlist.
$hl->uniq();
Sort the hostlist $hl and remove duplicate entries.
