SPARC Enterprise

These events include L2 cache misses, a hardware timer exception, interrupts, or some multi-threading-related control instructions.

When both are ready to run, they alternate cycles for superscalar instruction issue, and share the functional units according to need.

An important capability of the M-Series is the ability to mix processor generations and clock speeds in the same system and domain.

All M-Series servers can have both SPARC64 VI and SPARC64 VII CPUs installed and they will run at their native speeds, with no clocking down to the slowest CPU.

On April 17, 2007, a Sun SPARC Enterprise M9000 achieved 1.032 TFLOPS on the LINPACK benchmark, making it the fastest single system supercomputer at that time.

[5] On May 2, 2008, Sun SPARC Enterprise M9000 server achieved a world performance record on the TPC-H data warehousing benchmark at the 1 terabyte scale factor using the Oracle Database.
