drjzzz writes "Federal Computer Week reports that the National Nuclear Security Administration of the US Department of Energy is paying about $3 million of a $6.8 million collaboration between Silicon Graphics and the Universities of Maryland and Wisconsin to develop an open-source version of SpeedShop, SGI's performance analysis tools. This will redress what a SGI engineer characterizes as scarce analysis software for Linux. A "Pro" version will also be developed and sold by SGI. Maybe even those of us without access to ASCI White can tweak our boxen to do 3D simulations of complete nuclear detonations, NNSA's main interest. Now that's what I call homeland security and real respect for the spirit of the second amendment."
