I am setting up a Distributed Processing environment using cdsqmgr.
I have the following lines in my ~/.cdsenv
asimenv.distributed copyMode boolean t
asimenv.distributed remoteShell string "ssh"
asimenv.distributed loginShell cyclic "csh"
I found a cdsRemote.scr in /usr/cadence/IC610/share/cdsssetup/cdsRemsh and followed the instructions there. Somewhere in LINE 43 of this file, I see:
#remoteSystem=ssh # uncomment this line to configure for generic ssh
Since I do not have write privileges in /usr/cadence..., I copied
cdsRemote.scr to my home ~/cdssetup/cdsRemsh because the
instructions at the top of the file said so:
The default behaviour of the cdsRemote facility can be modified by
copying the file to a directory with a higher serach precedence
(such as $HOME/cdssetup/cdsRemsh/cdsRemote.scr) and then modifying
And so I modified the copy to read:
I have done the following necessary setup:
Add to my ~/.cshrc
setenv LBS_CLUSTER_MASTER calvin
Create a queue-config file with the following contents
Kill all cds... processes owned by root
$ ps -u root | grep cds
Run cdsqmgr as root
$ cdsqmgr ~/queue-config
Now, when I test using adptest, I get the following output:
BEGIN Analog Design Environment Distributed Processing Setup Test

Why is the cdsqmgr still using the rsh to login to the executiong
host, when I already set it to ssh in .cdsenv?
Why is the cdsqmgr still using the default cdsRemote.scr, when I
already copied a modified file in ~/cdssetup/cdsRemsh?
Don't know. Nothing obvious jumps out at me. Please contact tp so that somebody can debug this with you.

Whoops, something got messed up when I posted that. I meant to say contact customer support. I think the focus of my cursor slipped as I was typing in the URL... and it ended up as "tp".
Can you try again after changing the permission of ~/cdssetup/cdsRemsh/cdsRemote.scr to include execution permission?
chmod +x ~/cdssetup/cdsRemsh/cdsRemote.scr
