<br>
There used to be two reasons for running commands through a
non-graphical shell; one was that GUI was not yet available. The other
is that programs talk to each other through 1 dimensional streams, not
2D visual layouts. One reason has long since gone away, but the other
still holds. Vendors of pretty GUI interfaces forget the latter, they
aren't programmers. <br>
<br>
Integrating the GUI with the OS arguably benefits end-users but is
misterable for programmers; contrast remote administration of an NT
server with PCAnywhere (pushing bits of the GUI through phone lines) vs
X server/client, in the 90's. Really made MSWin a nutty choice for
servers (but that's my soapbox, sorry).<br>

Hello,<br>
<br>
<br>
do you know that there is an open source, entry level version of LSF available named Lava from<br>
<br>
<a href="http://www.hpccommunity.org/index.php?pageid=lava" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.hpccommunity.org/index.php?pageid=lava</a><br>
<br>
This might be helpful if you want to test without buying LSF licenses.<br>
<br>
Best regards,<br>
<br>

Dear all,<br>
<br>
We've just bought a program named CST <<a href="http://www.cst.de" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.cst.de</a>> Microwave Studio<span class="q"><br>
2009(CST MWS)<br>
Engineer from CST says their program could be scheduled by Platform LSF. Our<br>
cluster is built with Rockscluster, only torque or SGE is avaiable. We<br>
cannot affort LSF as it is too expensive.<br>
<br>
Engineer from Dell(vendor of our cluster) says torque, SGE and LSF have just<br>
the same functionality, what makes difference is stability, schedule<br>
algorithm and price.<br>
<br></span><span class="q">
We don't have LSF in hand, and engineer from CST refuses to demostrate<br>
running CST MWS with LSF.(They says they don't have LSF either, the test is<br>
carried on other customer's cluster.)<br>
<br></span><span class="q">
CST MWS is traditionally a program run on a single PC. Version 2009 is the<br>
first release with MPI parallell code. It uses a modified MPI Library.<br>
<br></span><span class="q">
Even console execution would start GUI interface. If no X server is found,<br>
it would redirect graphical output to *Xvfb*(a virtual X11 server that<br>
performs all graphical operations in memory)<br>
<br>
When I argue that many other computational electromagnetics programs such as<br></span>
FEKO <<a href="http://www.feko.info" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.feko.info</a>> can run in batch mode without any X output and<span class="q"><br>
can be sheduled directly by external job queueing system, engineer from CST<br>
declares that kind of program not starting a GUI is old-fashioned...<br>
<br></span><span class="q">
Are they telling the truth, or just lying?<br>
<br>
<br></span>
Best Regards,<br>
Jin, Yao<br>
