Here's one.
tar cf - <foldername> | ssh <compute node> "cd <desired top level dir>; tar
xvfBp -"
that will create <foldername> underneath your <desired top level dir> on
<compute node>
There are many variations including using rsync.
-P
Nothing rocks-specific about the above pipeline.

for tar, "-" is the name of file (stdin for extracting, stdout for creating)

(cluster) to root of compute node (compute-0-0). This is the command I
entered but its clearly not working. Any suggestions.
[root@cluster ~]# tar cf -eucalyptus-2.0.3-centos-i386 | ssh compute-0-0
cd; tar xvfBp-

You might get better/faster results asking for help on a more general Linux forum. Do you have a local Linux Users Group in your town?
This was the command you gave:
# tar cf -eucalyptus-2.0.3-centos-i386 | ssh compute-0-0 cd; tar xvfBp-
The directory (or file) named "-eucalyptus-2.0.3-centos-i386" must exist on the frontend, in a location relative to the directory in which you typed the command. I seldom see directories that start with a dash ("-"), so that's pretty suspect. In Linux/Unix, command-line options often begin with a dash. So most people avoid using a dash as the first character in a file name or directory name -- because it's ambiguous, the computer can't tell if you meant to give an option or refer to a file.
If you can do "ls -- -eucalyptus-2.0.3-centos-i386" and get some valid output, then that file/directory exists. If it responds with "ls: -eucalyptus-2.0.3-centos-i386: No such file or directory" then it doesn't exist. Note the crafty use us two dashes ("--") to tell the command to stop interpreting a dash as an option, but instead assume it's a filename.
On the compute-0-0 side, you first gave a command to change to the user's home directory ("cd"). With no arguments, "cd" just changed to /root. So you should find the directory at /root/-eucalyptus-2.0.3-centos-i386 on the compute node.
An alternative method, with my comments on the right side (don't type them):
# su - (become root)
# cd /path/to/eucalyptus-dir (substitute the real path)
# tar zcvf eucalyptus.tar.gz euc[TAB] (press the Tab key to auto-complete the dir name)
# scp eucalyptus.tar.gz compute-0-0:/path/where/you/want/it
(the path must exist)
# ssh compute-0-0 (log into a compute node)
# cd /path/where/you/want/it (move to where you put the file)
# tar zxvf eucalyptus.tar.gz (extract the directory)
