Introduction:Introduction:
You already know that Hewlett Packard Visualize Workstations are performance leaders in the industry, an d have be e n sin ce the ir introduction. What you may not know is that Visualize Workstations perform bette r than our competition on the toughest problems. As the complexity of the problem increases, so does the performance of HP Visualize Workstations utilizing PA-RISC architecture. The concept “the harder you work the better we perform” can be demonstrated with ANSYS Multiphysics.
With a long-standing global partnership, HP and ANSYS continue to offer a total collaborative engineering solution to customers -- providing the right tool for the right job. ANSYS offers a wide range of solutions beginning with the CAD integrated DesignSpace product to the mid-range, easy-to-use ANSYS/Professional product to full ANSYS/Multiphysics. No matter what the ANSYS application, HP has the platform of choice , from NT and UN IX workstations to high-end scalable UNIX servers.
ANSYS and HP provide ongoing support for joint customers. Benc hm arks are performed to show that ANSYS code is continually being optimize d to take advantage of new architectures. One of the fac t ors that enabl es ANSYS users to solve larger problems faster and cheaper is the non-stop improvement in computational power driving the high-tech industry. Hewlett­Packard's 64-bit Precision Architecture RISC microprocessors (PA-8x00) achieved leadership performance for ANSYS 5. 5 with the in troduc tion of the PA-8500 chip in 1999. The UNIX and NT workstations and servers introduced in 2000, along with ANSYS 5.6.1 extend the benefits of the HP/ANSYS solution to even higher levels by increased optimizations .

. These workloads are designed by ANSYS to gauge hardware performance. Because these benchmarks are designed and publishe d by ANSYS they are hardware vendor independent. The hp visualize j6000 data is taken from a benchmark performed by the HP Techn ic al Con sulting

Lab; and is also available on the ANSYS website
. In our comparison, two­way dual-processor machines were chosen bec ause of increase d sc al ability via thread based parallelism.
As the degrees of freedom in the benchmark increase, the complexity of the model increases. Therefore, for the purpose of this paper, an increase in the degrees of freedom equals an increase in complexity and more closely represents the type of problems being solved today by l arge custome r s.
Looking at the difference between the machines at e ach se parate de gree of freedom shows the relative performance of the competitor’s machines directly compared to that of the visualize j6000. It is important to note that each data point should only be compared with other data points at the same degrees of freedom, there is no relation between the j6000 at 23,658 degrees of freedom and the j6000 at 71,472 degrees of freedom. The total elapsed time is normalized into a relative performance number by dividing each time into the time for a reference system, in this case the hp visualize j6000.

This graph was generated by taking the total elapsed time from three different benchmark tests (models), each at different degrees of freedom and normalizing the data. The workloads se le c t e d for this ch art are from the ANSYS 5.6 public benchmarks: sms-bls (23,658 DF) , sms-blm (71,472 DF), and smb-blm (73,575 DF). Each of these workloads is a structural modal shell.
This graph shows that the Compaq Alpha 667 has a .057x perform anc e advantage to the j6000 on sms-bls. However, the j6000 is 1.40x faster than the IBM and 1.628x faster than the Sun. This workload, with only 23658 degrees of freedom, is considered to have low complexity.

As the complexity increases on sms-blm, the j6000 offers a 1.063x performance advantage over the Co m paq system and continues to increase on the IBM to a 1.423x lead and a 1.793x advantage over the Sun systems.
Again, as the complexity increases on smb-blm , so does the performance advantage of the j6000. The j6000 is 1.097x faster than the Compaq system, 1.566x faster tan the IBM, and 1.817x faster than the Sun system.
Similar results have been seen on other combinations of workload.

Summary:
Summary:Summary:
This data suggests that as the complexity of the workload increases so doe s the relative performance of the PA-RISC architecture.
We attribute this trend to the PA-RISC’s excellent floating point ability. Additionally, HP engine ers in th e Technical Server Applications Development team have been working ve ry c losel y with ANSYS to optimize this application on the PA-RISC platform for over five years.
As the complexity increases so does the number of floating point operations required to solve the model. The efficient execution of floating point operations is one of the greatest strengths of the PA-RISC processor. This leads to the increased performanc e as th e complexity increases. The harder you work the better we perform.
