ABAQUS V6.7 Benchmarks Sun Blade X6250 Cluster World Record

Friday Jan 25, 2008

The ABAQUS "Explicit" benchmark test suite was run on a mini cluster of Sun Blade X6250 blades with the recently announced 3.33 GHz dual-core Intel 5260. The Sun Blade X6250 mini cluster beats all posted results at the ABAQUS V6.7 website up to the eight cores.

Four 2 socket Sun X6250 blades with Infiniband interconnects were used and runs were made at different core levels: 1, 2, 4, and 8. Comparisons are presented against the current leading competitors' results also obtained with high performance interconnects and posted at the ABAQUS V6.7 website. This includes results from IBM, HP, and Intel platforms and clusters with current dual-core and quad-core Intel processors.

About The ABAQUS Explicit Module

This module designed for crash and high velocity impact analyses is very scalable and analysis models tend to be very large similar to CFD models. Timely results are best obtained using multiple processing units for typically large jobs either on a single multi core server in smp mode or on a multi node cluster of multi core platforms interconnected in dmp mode.

• The test cases in the ABAQUS "Explicit" benchmark test suite do not require much memory (all around a few hundred megabytes)
• The ABAQUS test cases scale very well up to 16 cores. All of the solvers in the Explicit module work in dmp mode on clusters. The ABAQUS default mode for MPI is HP-MPI.
• Based on the maximum physical memory on a platform the user can stipulate the maximum portion of this memory that can be allocated to the ABAQUS job. This is done in the "abaqus_v6.env" file that either resides in the subdirectory from where the job was launched or in the abaqus "site" subdirectory under the home installation directory.
• The test cases for the ABAQUS benchmark test suites all have a substantial I/O component. This I/O activity is primarily associated with temporary scratch files. Performance will be enhanced by using the fastest available drives and striping together more than one of them or using a high performance disk storage system with high performance interconnects.

World Record ABAQUS V6.6 on the Sun Blade X6250 Cluster

Wednesday Jul 11, 2007

Sun Blade X6250 posted World Record on the ABAQUS Explicit benchmark test suite the Sun Blade X6250 on the MCAE application ABAQUS V6.6. the Sun Blade X6250 used Xeon 3GHz DC 5160. On the various test cases Sun beats the Intel Supermicro by or by 1% to 39% !! The Sun Blade X6250 beats the Intel Supermicro even when you average all of the test case by an average 4% to 9% (geometric mean of all 6 tests cases at all cpu levels listed).

Both machines have 2 sockets and dual core processors. Runs were made at 1- 2- and 4-cores and a geometric mean was established at each of these "cpu" levels based on the 6 test cases in the benchmark test suite.

The Sun Blade X6250 with 3.0GHz Xeon EM64T 5160 (Woodcrest) processors and under 64-bit Linux SuSE SLES 10 beats all of the following platforms with results posted at the ABAQUS website and for all 6 test cases in the ABAQUS "Explicit" benchmark test suite and at the 3 "cpu" levels (1-, 2- & 4-"cpu's"):

About The ABAQUS Explicit Module

This module designed for crash and high velocity impact analyses (including wave propagation and inertia effects) is very scalable and analysis models tend to be very large similar to CFD models. Timely results are best obtained using multiple processing units for typically large jobs either on a single multi core server in smp mode or on a multi node cluster of multi core platforms interconnected in dmp mode.

Consequently this module is meant to run primarily in a multi cpu situation either in smp mode on a single large multi core machine or in dmp mode over a cluster of machines.

Abaqus/Explicit Benchmark Problems

The problems described below provide an estimate of the performance that can be expected when running Abaqus/Explicit on different computers. The jobs are representative of typical Abaqus/Explicit applications including high-speed dynamic impact events and quasi-static events with complicated contact conditions. The number of increments listed in the tables below are approximate and can vary somewhat depending on the hardware platform and the number of parallel domains.

E1: Car crash
This benchmark consists of passenger car impacting a rigid wall. The car is meshed primarily with shell elements of type S3RS and S4RS with isotropic hardening Mises plasticity material behavior. The various compenents of the car are connected using multi-point constraints and connector elements. Many of the suspension and drivetrain components are modeled as rigid bodies. The car, road surface, and wall are placed into a single general contact domain and the car is given an initial velocity of 25 mph.

E1
Increments: 62,934
Number of elements: 274,632


E2: Cell phone drop
This benchmark consists of a simplified model of a cell phone impacting a fixed rigid floor. The cell phone components are meshed using a variety of element types including C3D8R, C3D10M, and S4R. The material behavior is modeled using linear elasticity, isotropic hardening Mises plasticity, and hyperelasticity. The components are assembled using surface-based mesh ties and placed into a general contact domain that also includes the floor. The initial velocity and orientation of the cell phone is defined such that a severe oblique impact occurs.

E2
Increments: 87,369
Number of elements: 45,785
Memory requirement: 300 MB


E3: Sheet forming
This benchmark consists of forming a sheet metal part by the deep drawing process. The deformable sheet metal blank is meshed with shell elements of type S4R and uses an isotropic hardening Mises plasticity material model. The tools are meshed using surface elements of type SFM3D4R which are declared rigid. General contact is defined between the blank and tools. The analysis sequence consists of two steps. During the first step the blank is clamped between the binder and die and then during the second step the punch is displaced to form the part. Since the process is essentially quasi-static the computations are performed over a sufficiently long time period to render inertial effects negligible. The performance of this analysis is a direct measure of the performance of the three-dimensional general contact algorithm.

E3
Increments: 31,177
Number of elements: 34,540 (deformable only)
Memory requirement: 550 MB


E4: Projectile penetration
This benchmark consists of a projectile penetrating a steel plate at an oblique angle. Both the projectile and plate are meshed using hexahedral elements of type C3D8R and use a rate-dependent isotropic hardening Mises plasticity material model with failure. The projectile and plate are placed into a general contact domain with surface erosion. The edges of the plate are held fixed and the initial velocity of the projectile is specified so that the projectile passes completely through the plate.

E4
Increments: 12,433
Number of elements: 237,100
Memory requirement: 1400 MB


E5: Blast loaded plate
This benchmark consists of a stiffened steel plate subjected to a high intensity blast load. The plate is meshed using shell elements of type S4R and uses an isotropic hardening Mises plasticity material model. There is no contact.

E5
Increments: 81,716
Number of elements: 50,000
Memory requirement: 150 MB


E6: Concentric spheres
This benchmark consists of a large number of concentric spheres with clearance between each sphere. The spheres are meshed using hexahedral elements of type C3D8R and use an isotropic hardening Mises plasticity material model. All of the spheres are placed into a single general contact domain and the outer sphere is violently shaken which results in complex contact interactions between the contained spheres.

E6
Increments: 23,291
Number of elements: 244,124
Memory requirement: 1000 MB
