Sun wasa sinking ship, and Oracle just  yelled "Hold my beer!" and took the wheel at the last minute, Linux and the major x86 vendors were killing off all the old 'big unix' companies. It was just a matter of time before it would be Sun's turn. -- Prentice On 12/11/20 12:35 AM, Bill Abbott wr

One interesting take on this is my experience as a HPC user at JPL. At JPL we use both external and inhouse clusters (most recently, Halo and Aurora, just replaced by Gattaca) - they have a fairly consistent user environment - Maybe some changes in what packages are preinstalled (matlab, MKL, BL
