The Lenovo ThinkSystem SD650 has set a new four-node 2-socket performance world record with the SPECmpiM_base2007 metric from the MPI M2007 suite of the SPEC MPI 2007 Benchmark.

This document summarizes the SPECmpiM benchmark result for the ThinkSystem SD650 that was published on September 14, 2018. The document lists the result, summarizes the major components of the configuration under test, and provides the link to the relevant benchmark organization’s web site for details about the result.


The Lenovo ThinkSystem SD650 has set a new performance world record with the SPECmpiM_base2007metric from the MPI M2007 suite of the SPEC MPI 2007 Benchmark. The SPECmpiM Benchmark suite is the industry standard to evaluate MPI-parallel, floating point, compute intensive performance across a wide range of cluster and SMP hardware.

This new benchmark result, published in a new SPEC Report on September 14, 2018, demonstrates that the ThinkSystem SD650 continues Lenovo’s leadership with outstanding performance for the server industry.

The ThinkSystem SD650 has achieved the following score (1):

  • SPECmpiM_base2007 = 59.2

This result is the best four nodes performance in the industry, 20% faster than the SGI four nodes 2-socket result. (2)

About the ThinkSystem SD650

The ThinkSystem SD650 direct water cooled server is an open, flexible, and simple data center solution for users of technical computing, grid deployments, analytics workloads, and large-scale cloud and virtualization infrastructures. The direct water cooled solution is designed to operate by using warm water, up to 50°C (122°F). Chillers are not needed for most customers, meaning even greater savings and a lower total cost of ownership.

The ThinkSystem SD650 server and the n1200 DWC enclosure are designed to optimize density and performance within typical data center infrastructure limits. The n1200 DWC enclosure is a 6U rack mount unit that fits in a standard 19-inch rack and houses up to 12 water-cooled servers in 6 trays.

Lenovo XClarity Controller is an all-new hardware embedded management engine common in ThinkSystem servers. XClarity Controller features an uncluttered graphical user interface, industry standard Redfish-compliant REST APIs, and enables booting in half the time of prior generation servers, with up to 6x faster firmware updates.

Lenovo XClarity Administrator is a virtualized application that centrally manages ThinkSystem servers, storage, and networking. Via reusable patterns and policies, it ramps up and scales infrastructure provisioning and maintenance. It serves as a central integration point to extend your data center management processes to physical IT. Running XClarity Integrators in external IT applications, or integrating through REST APIs, helps you further speed services provisioning, streamline IT management, and contain costs.

About SPECmpiM

The SPEC MPI 2007 benchmark suite evaluates Message-Passing Interface (MPI)-parallel, floating point, compute-intensive performance across a wide range of cluster and symmetric multiprocessing (SMP) server hardware. This suite continues the SPEC tradition of giving users the most objective and representative benchmark suite for measuring and comparing high-performance computer systems.

SPEC MPI 2007 focuses on performance of compute intensive applications using the MPI, which means this benchmark emphasizes the performance of all of the following:

  • Type of processor
  • Number of computer processors
  • MPI Library
  • Communication interconnect
  • Memory architecture
  • Compiler used
  • Type of shared file system

The benchmark is not intended to stress other computer components such as the operating system, graphics, or the I/O system.
