Sun Blade 6048 Chassis with Sun Blade X6275: RADIOSS Benchmark Results

Significance of Results

The Sun Blade X6275 cluster, equipped with 2.93 GHz Intel QC X5570 processors and QDR InfiniBand interconnect, delivered the best performance at 32, 64 and 128 cores for the RADIOSS Neon_1M and Taurus_Frontal benchmarks.

  • Using half the nodes (16), the Sun Blade X6275 cluster was 3% faster than the 32-node SGI cluster running the Neon_1M test case.
  • In the 128-core configuration, the Sun Blade X6275 cluster was 49% faster than the SGI cluster running the Neon_1M test case.
  • In the 128-core configuration, the Sun Blade X6275 cluster was 49% faster than the SGI cluster running the Neon_1M test case.
  • In the 128-core configuration, the Sun Blade X6275 cluster was 16% faster than the top SGI cluster running the Taurus_Frontal test case.
  • At both the 32- and 64-core levels the Sun Blade X6275 cluster was 60% faster running the Neon_1M test case.
  • At both the 32- and 64-core levels the Sun Blade X6275 cluster was 4% faster running the Taurus_Frontal test case.

Benchmark Description

Altair has provided a suite of benchmarks to demonstrate the performance of RADIOSS. The initial set of benchmarks provides four automotive crash models. Future updates will add in marine and aerospace applications, as well as including automotive NVH applications. The benchmarks use real data, requiring double precision computations and the parith feature (Parallel arithmetic algorithm) to obtain exactly the same results whatever the number of processors used.

Please go here for a more complete description of the tests.

Key Points and Best Practices

The Intel QC X5570 processors include a turbo boost feature coupled with a speed-step option in the CPU section of the Advanced BIOS settings. Under specific circumstances, this can provide cpu overclocking which increases the processor frequency from 2.93GHz to 3.2GHz. This feature was was enabled when generating the results reported here.

Node to Node MPI ping-pong tests show a bandwidth of 3000 MB/sec on the Sun Blade X6275 cluster using QDR. The same tests performed on a Sun Fire X2270 cluster and equipped with DDR interconnect produced a bandwidth of 1500 MB/sec. On another recent Intel based Sun Fire X2250 cluster (3.4 GHz DC E5272 processors) also equipped with DDR interconnects, the bandwidth was 1250 MB/sec. This same Sun Fire X2250 cluster equipped with SDR IB interconnect produced an MPI ping-pong bandwidth of 975 MB/sec.
