[Beowulf] SGI to offer Windows on clusters

There was an interesting thread on MS HPC on this list in the past,  
rather than retype I'll post the URL to my older post:


For those that don't want to follow the link -- there is probably a  
decent market for the MS HPC product, especially for small or  
dedicated systems that may be servicing data collection devices like  
lab instruments or imaging systems that live in non-datacenter  
environments where single point of contact support from an ISV who  
knows your particular domain/market/field cold is essential.  There  
are many non-HCP markets now which need significant compute power  
that is accessible and usable by non HPC specialists and if MS can  
line up the proper systems integrators, consultants and resellers who  
can service the specialized markets then this could be pretty  

My company has had a Rocketcalc system running MS Cluster Server 2003  
in our colo cage for quite some time now, the feedback from the  
individual actively using it has been very positive.  Regardless of  
what happens it will be an interesting thing to watch.
