Ok, few DAKOTA issues here,

1) I tried running DAKOTA on CAHABA (note: mpirun in CAHABA is taken from /usr/local/lam/7.0.5/pgi/4.0/PBSPro/5.4.0/bin/mpirun) for some example test cases given along with the distribution and it gave me the same MPI_Init error message at the end.

so i used mpich mpirun in CAHABA i.e (mpirun taken from /usr/local/mpich/1.2.6/gnu/3.4.0/PBSPro/5.4.0/smp/bin/mpirun) and it ran without any MPI_Init error message at the end. This worked even for np greater than 1 as well.

on cahaba:
/usr/local/mpich/1.2.6/gnu/3.4.0/PBSPro/5.4.0/smp/bin/mpirun -np 2 dakota -i dakota_pce.in

To understand and use DAKOTA (Design and Analysis Kit for Optimization and Terascale Applications) toolkit certain basic concepts of optimization
should be known,

In mathematics, optimization is concerned with finding the maxima and minima of functions, possibly subject to constraints. Example: maximize the profit of a manufacturing operation while ensuring that none of the resources exceed certain limits and also satisfying as much of the demand faced as possible. Optimization has many practical applications in logistics and design problems.

In computer science, optimization is the process of improving a system in certain ways to increase the effective execution speed and/or bandwidth, or to reduce memory requirements. Despite its name, optimization does not necessarily mean finding the optimum solution to a problem. Often this is not possible, and heuristic algorithms must be used instead.

The reason we were getting a blank page in browser after logging into the administrator page was with having some blank lines at the end of class_auth.php file in classes directory. At the end of php script ?> remove any remaining blank lines.

This problem was found in mambo configuration file as well,

http://forum.mamboserver.com/archive/index.php/t-32414.html

http://forum.mamboserver.com/showthread.php?t=9482&page=2

a diff between revision 1 and revision 3 revealed it.

In the administrator page there are two logouts, one among the toolbar and other at the right end. the logout in the right end closes the window and the logout in the toolbar goes back to the index page with user as "admin".

The problem with display in Limbo was, in the config.php file we have to set the URL as https:// instead of http://
the reason being, after index.php is loaded, the requests for certain images to be displayed will be sent to pubcookie server and since Pubcookie requires authentication these requests will not be valid and gets rejected.

also in your .htaccess files you have to add

PubcookieAppID username or anyname

pubcookie application ID is used to give a common cookie name which changes with the directory path.
for more information refer http://pubcookie.org

In the registerExtAuth() function $conn->Execute("INSERT INTO #__users (name,username,email,password,registerDate) VALUES('".dbencode($username)."','".dbencode($username)."','','','$time')" );

There is a plethora of CMS available, I found phpCMS, Guppy and CathDesign CMS to be ideal for our requirements,

http://www.phpcms.de/index.en.html

http://www.freeguppy.org/

http://cms.cathdesign.nl/

here is a link comparing the above three CMS

http://www.opensourcecms.com/index.php?option=com_wrapper&Itemid=139

Based on comparisons Guppy or phpCMS looks good to test (actually guppy has more security features)
but unfortunately guppy is not available in english, it is available in spanish, german, russian, italian languages !!

I will try phpCMS to begin with...

Thanks,

I have listed down some "things to be done" and my experience with myVOCS usage,

1) for a new user the first question will be " What are VO's ? how will it be useful ? " ...something which has to be made clear so that it will be used.
The link "What is this tool" is a link to yubnub, rather this can be customized explaining the concept of myVOCS (yubnub relationship) and giving some more examples.

2) Once a user gets into any VO (say cms), there should be some link to get back to myVOCS page or see the list of subscribed VO's to jump into.

3) There should be a create command on myVOCS page and a small list of created commands and a brief description of the same.
