sorry if this is an easy thing, but I tried to make it run the whole morning, but it doesn't work so far...
I am logged in on a visualization node of a high performance cluster. On this node I can run several gui-based software for the postprocessing of my cfd-data.
As the visualization node is always very busy, I would like to do the compute nodes the work.
My idea was to submit a bash script where I tell the compute nodes to start the specific software and to forward the display to my local display.
I read out the adress of my display with
and tried to start the software on the compute node with the following:
As this did not work, I also tried this:
In both cases no X-window opened on my screen.
As I am a noob in unix I would be happy about any advice.
Hi,
I am trying to get the cpu usage of a job/process. The machine that has these jobs is a cluster with 1 master node and 10 compute nodes.
Now, the complexity is that not all jobs are on the master node. So, in order to get the cpu usage of a job at another node, I have to ssh into it and... (0 Replies)
Guys, have any idea for the script like this? also to compute w/ decimal.
thanks
a=10
b=20
c=30
d=40
if a < b then ( a -b)*1024 = free space
b + (c -d) = total space
if a > b then (b / d)*1024 = cpu (3 Replies)

Hi,
Is it possible to have a Solaris cluster of 2 nodes at SITE-A using SVM and creating metaset using say 2 LUNs (on SAN). Then replicating these 2 LUNs to remote site SITE-B via storage based replication and then using these LUNs by importing them as a metaset on a server at SITE-B which is... (0 Replies)

Tree::Simple::Visitor::CreateDirectoryTree(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::CreateDirectoryTree(3pm)NAME
Tree::Simple::Visitor::CreateDirectoryTree - A Visitor for create a set of directories and files from a Tree::Simple object
SYNOPSIS
use Tree::Simple::Visitor::CreateDirectoryTree;
# create a Tree::Simple object which
# represents a directory heirarchy
my $tree = Tree::Simple->new("www/")
->addChildren(
Tree::Simple->new("conf/")
->addChildren(
Tree::Simple->new("startup.pl"),
Tree::Simple->new("httpd.conf")
),
Tree::Simple->new("cgi-bin/"),
Tree::Simple->new("ht_docs/"),
Tree::Simple->new("logs/")
->addChildren(
Tree::Simple->new("error.log"),
Tree::Simple->new("access.log")
),
);
# create an instance of our visitor
my $visitor = Tree::Simple::Visitor::CreateDirectoryTree->new();
# pass the visitor to a Tree::Simple object
$tree->accept($visitor);
# the www/ directory now mirrors the structure of the tree
DESCRIPTION
This visitor can be used to create a set of directories and files from a Tree::Simple object hierarchy.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter", "setFileHandler"
and "setDirectoryHandler" methods to customize its behavior.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are used to create the directory tree, it can be basically used as a node pre-
processor. An example usage of this might be to enforce the 8.3 naming rules of DOS, or the 32 character limit of older macintoshes.
setFileHandler ($file_handler)
This method accepts a CODE reference as its $file_handler argument and throws an exception if it is not a CODE reference. This method
can be used to create custom file creation behavior. The default behavior is to just create the file and nothing else, but by using
this method it is possible to implement some other custom behavior, such as creating a file based on a template. The function is passed
the full path of the file to be created (as built by File::Spec).
setDirectoryHandler ($dir_handler)
This method accepts a CODE reference as its $dir_handler argument and throws an exception if it is not a CODE reference. This method
can be used to create custom directory creation behavior. The default behavior is to just create the directory and nothing else, but by
using this method it is possible to implement some other custom behavior, such as creating a directory on a remote server. The function
is passed the full path of the directory to be created (as built by File::Spec).
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
The tree is processed as follows:
Any node which is not a leaf is considered a directory.
Obviously since files themselves are leaf nodes, this makes sense that non-leaves will be directories.
Any node (including leaf nodes) which ends in either the character "/" or "" is considered a directory.
I think it is a pretty standard convention to have directory names ending in a separator. The separator itself is stripped off
before the directory name is passed to File::Spec where the platform specific directory path is created. This means that it does
not matter which one you use, it will be completely cross platform (at least as cross-platform as File::Spec is).
All other nodes are considered to be files.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
