I just got this press release from ANSYS, Inc.
To summarize, on of the America's cup Yacht teams just built and ran a model with over 1 billion cells in it. Modeling the sales, ocean and all. They don't say if it was FLUENT or CFX, but we know it was one of the two.
Wow! And this was on a cluster ranked 135... not even in the top 100 of clusters. The press release is kind of vague on details but it looked like it was an HP cluster with 208 server blades. Don't know how many cores per blade.
When I was in the basement of the math building punching cards for my FORTRAN class I would have never thought this possible.
