Hi, Mark,
We, on the other hand, would recommend cluster computing!
(yet another shameless plug).
On a serious note, now that we've figured out clusters, I'm
looking at interfacing PDx-Pop to grids. I've done some reading
up on the Sun Grid Engine. The nice feature of SGE is its
heterogeneity (Windows/Linux/UNIX) and of course the improved use
of existing corporate CPU power. [Internal versions of PDx-Pop have
the same heterogeneous abilility to access either Windows or Linux servers].
Can you share with us some details on the grid you've implemented at GSK?
Bill
ps I tried your code (with Compaq 6.6B and it worked fine, although
the output is a bit sparse and is hard coded with "GSK". I guess
I'm not the only "shameless plugger" out there ;)
