Sun Studio at SuperComputing; also, now in Rocks roll



Sun Studio is now in the Rocks roll both for Solaris and Linux. You will find Sun Studio 12 update 1, Sun ClusterTools and Sun Grid Engine in the Linux roll here at: http://www.rocksclusters.org/wordpress/?page_id=107 and for Solaris roll here at: http://www.rocksclusters.org/wordpress/?page_id=108 . Bringing Sun Studio to Rocks makes it more readily available for Cluster development, primarily in research organization.

If you arent familiar with the Rocks distribution, it is basically an open-source Linux cluster distribution that enables end users to easily build computational clusters, grid endpoints and visualization tiled-display walls. Rocks is used by researchers to create their own clusters. You can get more information about Rocks here at their site (here).

Sun will be in SuperComputing 09, highlighting Flash technology and many other future technologies its working on. Come join Sun at Birds of a Feather session and at the Whisper Suite . For more info, follow this link.

Sun Studio OpenMP gets 12x improvement on Seismic benchmark on SLES10


This story is hard to pass up:  Sun's BestPerf blog (read the details here) recently reported how they got a 12x performance improvement over a single-threaded version on an important Seismic (Reverse Time Migration) benchmark using Sun Studio's OpenMP feature on SLES10. Its a great story of how Sun can deliver performance through a combination of Sun Studio and new Hardware (via Sun Storage F5100 Flash Array). Yes, this is the same Flash Array that has been the talk of the town and has notched up several World Record wins.
Several points come to mind:
  • Sun Studio and OpenMP are key to exploiting parallel performance. Not just with Flash, but also with multiple cores now becoming the mainstay in chip offerings. Multi-threading, parallel performance (and parallel programming, for those who are willing to take the effort) is going to be even more critical to fully utilize system resources now and into the future.
  • Sun Studio performance here is highlighted on SuSE 10. Note this, because I've had to defended the impression that Sun Studio doesnt do as well on Linux; it does. Sun Studio does not leave any performance, features, tools, options, optimizations out of its offering on Linux.
  • The Flash Array Storage alone gets a 2.2x performance win over 15K disks. But the combination with Sun Studio in achieving parallelism that the Flash Array Storage can exploit is even more attractive.

About

I have worked with Sun and Oracle for 25 years now; in compilers and tools organization for most of these years followed by a couple of years in Cloud Computing. I am now in ISV Engineering, where our primary task is to improve synergy between Oracle Sun Systems and our rich ISV ecosystem
