Hello John,
Is it possible for you to share the scripts that you had generated to
run Ansys in the Alchemi grid.
Thanks
V Anand

Anand,
Sorry for the slow response....been out on business. Anyway, I'm not
sure I understand your question.
I will say that alchemi does not have any reporting information
available in regards to the node capabilities with the exception of
processing power (if this is what you are asking?).
Therefore, if you have specific applications that are to be utilized on
a node then you should have a dedicated manager that is connected to
that node set and that node set only. The manager will evenly distribute
the problem load over all executors attached. This means that if you
have an executor not capable of solving your problem you will be
waisting a process thread (and possibly create zombies... I have noticed
some of this happening).
I'm not sure if the manager can tell this and remove the node (can
someone else help here, as I have not preformed any testing of this nor
read this anywhere).
If you like I can send you a simple set of scripts that will take data
from input text files and apply them to an ANSYS problem over the
alchemi grid (you will have to generate the text files yourself). It is
complicated a bit since the jsub program is not capable of using the
schema/language (XPML) as in the Gridbus Broker. This means you have to
keep track of job numbers and file renames yourself.
I hear this may be included at a latter date or you can set up a gridbus
broker (something I have not done yet but intend on doing soon).
Give me a few days and I'll start to send you some scripts (Perl and
VB). If you like, you can give me an idea of your problem set and I can
help with a grid implementation outline.

Hi John,
A quick question regarding running Ansys in a distributed environment.
In a cluster we submit the job in parallel or distributed Ansys using
scripts and the HPC schduler like Open PBS takes care of allocating it
to a node that is free. We use the qsub and give information regarding
number of processors and nodes.
Is a similar thing possible in Alchemi.
Currently I am working through with the examples.
Any help/suggestions is deeply appreciated.
Thanks
V Anand
