DESCRIPTION
Functions in this module are for the implementation of the script parpush.
parpush
The main function is parpush
:
(
$okh
,
$pid
) = parpush(
configfile
=>
$configfile
,
destination
=> [
'cluster1:/path1'
,
'cluster2:/path2'
],
scp

$scp
,

=>
$scpoptions
,
sourcefile

and destination
are required. The other arguments are optional.
In a list context returns two hash references ($okh, $pid)
.
%$okh
-
Is a hash with keys the names of the machines considered during the connections. The value is true (1) if all the connections with the corresponding machine were closed succesfully, false otherwise.
%$pid
-
Is a hash with keys the names of the machines considered during the connection. The value is an anonymous list with the process identifiers of the connections (
undef
if the fork failed) to that machine.
