Sun's Performance on Reverse Time Migration

Two BestPerf blog entries address performance of Sun systems in relation to reverse time migration. The first reports on results from a Sun Blade 6048 Modular System with 12 Sun Blade X6275 server modules clustered together with QDR InfiniBand and using a Lustre File System with QDR InfiniBand to show performance improvements over an NFS file system for reading in Velocity, Epsilon, and Delta Slices and imaging 800 samples of various various grid sizes using the Reverse Time Migration. A second entry demonstrates reverse time migration with optimal checkpointing, in SMP "THREADS" Mode. The test used a Sun Fire X4270 server configured with four high performance 15K SAS hard disk drives (HDDs) and a Sun Storage F5100 Flash Array. This benchmark compares I/O devices for checkpointing wave state information while processing a production seismic migration.

Benchmarks from Oracle OpenWorld

An index of benchmarks announced during the Oracle OpenWorld conference is posted at the BestPerf blog site. There are 32 benchmarks listed with links to detailed information for each under the following headings: CMT servers, SPARC64 servers, X86 servers, HPC, storage, and additional CMT.

Sun SPARC Enterprise T5440 Achieves World Record SPECweb2005

A world record SPECweb2005 performance result of 100,209 SPECweb2005 on the Sun SPARC Enterprise T5440, running Solaris 10 10/09 Sun Java System Web Server 7.0 Update 5, and Java Hotspot Server VM was recorded. T5440 delivers 21% greater SPECweb2005 performance than the HP DL370 G6, 40% greater performance than the HP DL 585 G5, and two times the performance of HP DL 580 G5. Get all the details.

CP2K Ab-initio Dynamics Applications Software and Sun Blades

Clusters of Sun Blade X6275 and X6270 server modules were used to run benchmarks using the CP2K ab-initio dynamics applications software. The X6270 cluster with Dual Data Rate (DDR) InfiniBand experienced a slowing in the increase rate of scalability at 16 nodes, whereas the X6275 cluster with QDR InfiniBand continued its scalability to 72 nodes. Dynamics simulation is used to determine the trajectories of atoms or molecules over time, and is important to materials science research.

ProMAX Performance on Sun Blade 6048/X6275 Cluster

A cluster of 48 Sun Blade X6275 server modules in a Sun Blade 6048 Modular System was configured with QDR Infiniband and a Lustre File System to demonstrate performance on ProMAX, which is integrated with Halliburton's OpenWorks Geoscience Oracle Database to access prestack seismic data and populate the database with seismic images. The 3D Prestack Kirchhoff Time Migration showed excellent scalability while utilizing the QDR Infiniband Lustre Filesystem. Namely, 70808 Traces: 144x improvement going from 1 to 72 nodes; and 283232 Traces: 98x improvement going from 1 to 96 nodes. BestPerf blog contributor Melinda McDade writes that the super linear scalability is attributed in part to data caching effects.

Highest Eight and Four-processor Results on the Two-tier SAP SD-Parallel

In case you missed it, as of October 12, 2009, four Sun Blade X6270 (2 processors, 8 cores, 16 threads), running SAP ERP application release 6.0 enhancement pack 4 (Unicode) with Oracle Database on top of Solaris 10 OS delivered the highest eight-processor result on the two-tier SAP Sales and Distribution-Parallel Standard Application Benchmark. Additionally, two Sun Blade X6270 with the same software delivered the highest four-processor result. This benchmark highlights the near-linear scaling of Oracle 10g Real Application Cluster runs on Sun hardware in a SAP environment.

Sun Storage 6180 Over 70% Better Price/Performance Than IBM

The SPC-1 benchmark demonstrated the Sun Storage 6180 Array's price/performance advantage, which equaled 72%, over the IBM DS5020. The array also outperformed the HDS 2100 by 27%, and is 50% faster than the previous generation, Sun Storage 6140 Array and IBM DS4700.
