Linux and Top500.org

RHEL 7 and CentOS 7 have officially been released this week.

We have very worthy group of major distributions that are prevalent in corporate space:

RHEL

SUSE

Ubuntu
I am amazed variety of features and options they now offer even in the default installations.

As I visit many different customers, one item is so obvious: Linux is everywhere (in one form or another: cloud, virtualization, and so on). Mainstream Unices (AIX, HP-UX, Solaris, and others) - just about everyone I met had the same projects in mind: migration away from them...

Somebody asked me several days ago what I though about the future of mainstream Unix operating systems. I did not need to answer it:

Top500.org

Only several of the top 500 supercomputers run operating system other than Linux:

485 run on some Linux

12 run on some Unix

2 run on Windows

1 runs on mixed O/S
Overall, 97% of all supercomputers in the June 2014 listing are on Linux.

Intel continues to provide the processors for the largest share (85.4 percent) of top 500 systems. The share of IBM Power processors remains at 8 percent, while the AMD Opteron family is used in 6 percent of the systems, down from 9 percent on the previous list.

I guess market has spoken loud enough.
