parallel code in

Yes but...that brings out my point, this is implying that _everyone_
would need HPC server. And seeing how much that costs for the CX1, I'm
curious to see how the research departments will be able to cope with
the licensing issues and TCO of using the MS solution compared to the
FOSS and/or POSIX proprietary approach. There is also a question of
readily available resources that will be able to run the code MS
flavored code, there are many MPI+posix clusters out there, none that I
know of that run MS HPC.<br>

<p class="MsoNormal">On that node, here are my questions to the MS
implementation
of clustering (and how CX1 will actually be usable or how one will be
able to
develop _for_ execution on one of the MS based CX1):<br>
<br>
Currently, most of our users are under Linux on their WS so that they
can
develop something that will potentially run off a big cluster. This
implies the
users are under a POSIX compliant OS with good MPI/OpenMP/threading
support,
which waters down to Linux or OSX (those Power Macs are impressive and
*silent*).<br>
<br>
Where I have reserves about the MS solution is as follows: how will MS
users be
able to develop parallel code locally on their WS without needing to
upgrade/change their hardware/OS to be compatible with a MS based
cluster/CX1.
It's not made clear weather the "clustering tools" are tightly
integrated into the CX1 platform or if, as with Linux or OSX, it's a
simple
case of installing mpi-ish libs (and a few others).<br>
<br>
With the pricing scheme, I can't imagine _every_ dev getting their own
CX1 to
play on so I believe adoption of the platform required ease of
installation
(ie: all tools should be available throughout windows 2000-xp-vista)
and
shouldn't even be version specific (IMHO)...but that's me being used to
Linux
heh! ;)<br>
