[Radiance-general] ranimate Host directive

[Terrance Mc Minn]

I have been experiencing errors when attempting to use ranimate across 
multple host computers. Specifically if the remote host does not have 
the same user name accounts.

extracted from the .ran file:
host= localhost 1 /export/ranimate/current muser
host= remote1 1 /export/ranimate/current
host= remote2 1 /export/ranimate/current ruser

where muser is the user account name where the ranimate command is 
issued and ruser is the user name on the remote2 computer.

The ranimate man page states:

*host*
    A host to use for command execution. This variable may be assigned a
    host name, followed by an optional number of parallel processes,
    followed by an optional directory (relative to the user's home
    directory on that machine), followed by an alternate user name.
    Multiple /host/ assignments may appear. It is not advisable to
    specify more than one process on a single-CPU host, as this just
    tends to slow things down. The default value is "localhost", which
    starts a single process in the current directory of the local machine. 

clearly it seems that the intended operation is to work from the users 
account

However when the fourth parameter is used eg remote user name, ranimate 
only users this in the ssh command and reverts to the master user name 
in the cd commands (The user name on the master computer that initiated 
the ranimate process). This can be seen in the dump from remote 2 using 
the ps x command:

ruser    4403  1.0  0.1   4712  1700 ?        Ss   15:58   0:00 bash -c 
cd ~muser ; cd /export/ranimate/current ; pfilt -1 -e -2 -x 1854 -y 822 
-pa 1 animat
ruser    4404  3.0  0.0   2052   788 ?        D    15:58   0:00 pfilt -1 
-e -2 -x 1854 -y 822 -pa 1 animation_process_network/frame022.unf


Is this behaviour the intended process or a missing issue in the man pages.

It should also be noted that as soon as a dummy account is made on the 
remote2 computer under the name of muser, everything continues as 
expected (without any changes to the ran file - that is still using the 
ruser parameter)!
