[Beowulf] Not OT, but a quick link to an article on InsideHPC

Chris,

Thanks for clarifying the difference between EKOPath/Path64 and 
Pathscale. I probably meant to say Path64 and not Open64.

So are you saying the pathscale.com site has been up consistently, and 
is still up? I've been trying to get there for months, originally to see 
what the latest version of your compiler was and update our installation 
the latest version if necessary, and then I kept checking to see if you 
were still in business.  I still can't get there today. I've tried from 
work, home, etc. I can't get there right now, in fact. I type in 
"pathscale.com" in the address bar of Firefox, and just get a spinning 
wheel in the tab and the text "Connecting..." If pathscale,com is still 
up, I'd be happy to work with you to trouble shoot this problem.

I was able to get to some sort of customer login portal, but not the 
main pathscale.com site. This is why I thought Pathscale was already out 
of business, and how I stumbled on that post for whatever open source 
compiler that was.
