I dont see why so please explain?
HPC architecture involves atypical services, hardware, and frameworks versus normal server computing, even compared to thousands of cloud machines. Wikipedia has some good coverage of popular approaches [1]. A properly built kernel is an essential part of an HPC deployment, particularly with respect to the scheduler and memory management. Build options appropriate for embedded all the way to normal servers are often inappropriate for HPC.
SUSE Linux has a large following in HPC, but it's not just a product of their general server work.
