Peltier via RT To: chao@fas.sfu.ca, ljilja@fas.sfu.ca CC: mma98@sfu.ca Hi Ljiljana, I spoke with a couple of your students yesterday and notified them that on *all* GNU/Linux machines there is a /local-scratch directory on them. The sizes of these directories varies but on the ENSC 427 lab machines this amounts to roughly 200GB. This should be more than sufficient to run their simulations. Of note, by running their simulations in this directory they will also run faster since there is little latency involved. The only thing they must ensure they do is copy the results of the simulations back to their home directory. This will improve performance and allow them to get what they want to get done; done. This has been the recommended mode of operation for all users of The Colony HPC cluster, however, it was never really documented for FASNet machines as a whole. Also, while I mention that this is on GNU/Linux machines only right now, we are discussing adding this functionality to our Solaris workstations that have sufficient disk space. I hope this is suitable enough for you. -- James A.

The work around for this is to install there own version of ns-2 so they will have a full access to their own file systems files.

To: ljilja Subject: ENSC 427 - Digital clock Hi. Dr. Trajkovic, I just wanted to let you know that I found the the digital clock and also wanted to provide you with the steps on how to open it in-case that you want to share it with other people in the class: 1. Run the Solaris OS. 2. Click on the Applications button (4th triangular button above the 'Text Note' icon) 3. Click on Applications 4. Application Manager box will show up 5. Double click on Desktop_Tools 6. Double click on Digital Clock. best regards, Shervin Asgari Pour Systems Engineering Option Simon Fraser University 8888 University Drive | Burnaby, BC, Canada | V5A 1S6 saa34@sfu.ca | www.sfu.ca ****************************************************************************** Date: Mon, 07 Feb 2011 10:42:41 -0800 From: "Chao C.

Cheng" To: ljilja@cs.sfu.ca CC: "'Chao Cheng'" Subject: Re: Firefox for Solaris machines I was working with two of your students and we discovered that it was better to use the machine called "css" as the firefox server. When firefox and OPNET are opened at the same time, the display on dogwood is not clear on dogwood. Please kindly change the note to replace "dogwood" with "css". Cheers!

Cheng" To: Marish Lalwani CC: ensc-help , chao , Ljiljana Trajkovic Subject: Firefox for Solaris machines Hi, Marish: For your problem with Firefox on Solaris desktops in the lab, here are the answers: You have Solaris desktops running Sun OS 9 which is not compatible with newer version of Firefox locally. Yet, you can still run Firefox remotely on a server and display it on the local Solaris desktop by following the commands and steps: 1. On local terminal window: hostname (to find out your local host name) xhost +dogwood (to add dogwood - a Solaris 10 server to your X-Windows access list) ssh dogwood (to remote login to dogwood - use your ID and password at the prompt) 2. On remote dogwood window: 2.1 For C shell users: setenv DISPLAY hostname:0.0 (redirect dogwood display to your lcoal display - replace hostname to your host name from step 1) OR 2.2. For bash users: export DISPLAY=hostname:0.0 (redirect dogwood display to local display - replace hostname to your host name from step 1) 3. On dogwood remote window: /usr/local/bin/firefox & (to start firefox on dogwood and display to your local display) Hope this helps, Cheers!

They are reachable on the SFU campus (all labs). The students may run the tutorial by simply coping the URLs to the browser address bar: file:///ensc/local2/opnet/14.0.A/doc/modeler/modeler.html file:///ensc/apps/opnet/15.0.A/doc/modeler/modeler.html file:///ensc/apps/opnet/16.0.A/doc/modeler/modeler.html Note: Students have to be logged to the SFU network (Linux or Unix machines).
