In the parallel extension we have created in GridSAM. We have a new
element called <mpi:MPIApplication/> that extends the
jsdl:posix:POSIXApplication_Type. Therefore the MPIApplication inherits
the arguments, executable, etc. with the additional elements to specify
parallelism.
Roughly....
<xsd:complexType name="MPIApplicationType">
<xsd:complexContent>
<xsd:extension base="jsdl-posix:POSIXApplication_Type">
<xsd:sequence>
<xsd:element ref="ProcessorCount"/>
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
<xsd:element name="ProcessorCount" type="xsd:positiveInteger"/>
<xsd:element name="MPIApplication" type="MPIApplicationType"/>

Just a quick note to say that the main reason for doing the parallel
jobs stuff next (probably starting from the base proposed by the people
from Barcelona; they've identified the stuff that's needed after all) is
that otherwise there'll be several different groups doing it themselves
in an incompatible way. To me, that says it is an *excellent* idea to
foster a standard extension for this and to expedite this. OK, I think
other extensions/improvements are more important in the grand scheme of
things, but the fact that people are doing it now forces our hand.
Looking at the parallel proposal, I have to ask how it is supposed to be
combined with the POSIX extension, since without that it's not going to
work (still need command-line args, env-vars, etc.) Once we've nailed
that down, I think it will be just A Simple Matter Of Writing. :-)
Donal.
