> When performance and scale matter, then Linux appears to the operating system of choice, wouldn't you agree? Perhaps the Solaris 11.3 beta will make a dent in the TOP500 list?
It is few reasons why Linux is used on HPC systems in order of importance:
- Linux is only system supported on delivery by hardware vendor MPI related software
- it is known for people who support it in exact env (usually those people are enough skilled to not relay on external OS support)
- on the market is much more people able to customize it on using APUs/GPUs (Most of biggest HPC installations are working on customized hardware)
As you see performance on above list does not appear.
Biting the hand that feeds IT
