==High-performance computing==
Sun marketed the [[Sun Constellation System]] for [[high-performance computing]] (HPC). Even before the introduction of the Sun Constellation System in 2007, Sun's products were in use in many of the [[TOP500]] systems and supercomputing centers:
* [[Lustre (file system)|Lustre]] was used by seven of the top 10 supercomputers in 2008, as well as other industries that need high-performance storage: six major oil companies (including [[BP]], [[Shell plc|Shell]], and [[ExxonMobil]]), chip-design (including [[Synopsys]] and [[Sony]]), and the movie-industry (including [[Harry Potter film series|Harry Potter]] and [[Spider-Man]]).<ref>{{cite video

* Sun Fire X4500 was used by high-energy physics supercomputers to run dCache
* Sun Grid Engine was a popular workload scheduler for clusters and computer farms
* [[Sun Visualization System]] allowed users of the [[TeraGrid]] to remotely access the 3D rendering capabilities of the ''Maverick'' system at the [[University of Texas at Austin]]
* [[Sun Modular Datacenter]] (Project Blackbox) was two Sun MD S20 units used by the [[Stanford Linear Accelerator Center]]

The ''Sun HPC ClusterTools'' product was a set of [[Message Passing Interface]] (MPI) libraries and tools for running parallel jobs on Solaris HPC clusters. Beginning with version 7.0, Sun switched from its own implementation of MPI to [[Open MPI]], and donated engineering resources to the Open MPI project.

Sun was a participant in the [[OpenMP]] language committee. Sun Studio compilers and tools implemented the OpenMP specification for shared memory parallelization.

In 2006, Sun built the [[Tsubame (supercomputer)|''TSUBAME supercomputer'']], which was until June 2008 the fastest supercomputer in Asia. Sun built ''Ranger'' at the [[Texas Advanced Computing Center]] (TACC) in 2007. Ranger had a peak performance of over 500 TFLOPS, and was the sixth-most-powerful supercomputer on the TOP500 list in November 2008.
Sun announced an OpenSolaris distribution that integrated Sun's HPC products with others.<ref>{{cite web
