[Beowulf] doubt about job queuing systems

[Jin, Yao]

Dear all,

We've just bought a program named  CST <http://www.cst.de> Microwave Studio
2009(CST MWS)
Engineer from CST says their program could be scheduled by Platform LSF. Our
cluster is built with Rockscluster, only torque or SGE is avaiable. We
cannot affort LSF as it is too expensive.

Engineer from Dell(vendor of our cluster) says torque, SGE and LSF have just
the same functionality, what makes difference is stability, schedule
algorithm and price.

We don't have LSF in hand, and engineer from CST refuses to demostrate
running CST MWS with LSF.(They says they don't have LSF either, the test is
carried on other customer's cluster.)

CST MWS is traditionally a program run on a single PC.  Version 2009 is the
first release with MPI parallell code. It uses a modified MPI Library.

Even console execution would start GUI interface. If no X server is found,
it would redirect graphical output to *Xvfb*(a virtual X11 server that
performs all graphical operations in memory)

When I argue that many other computational electromagnetics programs such as
FEKO <http://www.feko.info> can run in batch mode without any X output and
can be sheduled directly by external job queueing system, engineer from CST
declares that kind of  program not starting a GUI is old-fashioned...

Are they telling the truth, or just lying?


Best Regards,
Jin, Yao
