    • Test Report December 2002 For Dell TM Computer Executive Summary Corporation. Today we see the widespread use of engineering/technical workstations to support complex applications in design, analysis, finance, digital content creation and software development. Companies deploying this technology understand that improvements in the performance of these tools can help to shorten product or project design cycles, which can contribute to lowering of costs and/or provide a competitive time to market Comparative Study advantage. As a result, designers, engineers and project managers alike continue to search for opportunities to boost the system and application performance. One area to consider for its potential to enhance workstation of performance is the addition of a second processor on workstations with dual processor capability. Single vs. Dual NSTL was contracted by Dell Computer Corporation to assess the performance advantage of a dual Intel® Xeon™ processor based system vs the same system equipped with a single processor. In order to determine the Processor System performance of each system, NSTL conducted a series of benchmark tests employing workstation class applications. The tests that were conducted comprised of the following applications and benchmarks: Adobe® Inside: Photoshop®, Ansys®, Nastran®, BAPCo® SYSmark®, Linpack, Fluent and SPEC CPU2000. Detailed information on each benchmark can be found in the Results section. Test Methodology All benchmarks were run on a clean system using the same image file. The system configuration was changed Test Environment by setting the NUMPROC parameter in the boot.ini file. The dual processor workstation was configured with Test Results two Xeon processors with Intel® NetBurstTM microarchitecture. The system contained 2 GB of ECC Memory with two 36 GB SCSI drives configured as one RAID 0 logical drive. The complete system configuration can About NSTL be found in the Test Environment section. NSTL found that for applications that can utilize both processors, the dual configuration performed better than Key Findings: the single processor system. The SPECcpu benchmark, which measures CPU performance, displayed a 79% increase in the performance of the dual processor system over the single processor system. The Ansys * The Dual Intel® Xeon™ benchmark performs linear and transient structural analysis on real-world models.

The Linpack benchmark measures the execution rate in MFLOPs (millions of system for all benchmarks. floating point operations per second). NSTL testing showed that the dual processor system provides a 38% increase in performance over the single processor system. The increase in performance was proportional to the *The Dual processor system increase in the size of the matrices. The Fluent benchmark, which performs complex calculations to obtain flow displayed up to a 40% increase rates for various models, showed a significant increase in performance when run on the dual processor configuration. The performance increases ranged from 27% to as high as 54% better on the dual processor over the Single processor system. The final benchmark test NSTL conducted was the Sysmark benchmark which measures performance system for the Ansys using a mix of applications in a multitasking environment. The results of the benchmark show that adding a benchmark second processor to the test system in multitasking environments improved the performance of office applications by 8% and internet content creation by 24%. The NSTL testing showed that for all the * The results show that the benchmarks, the dual processor configuration performed much better then the single processor configuration. increase in the time saved by using a dual processor system is proportional to the increase in the complexity of the models for the Nastran benchmark.
    • NSTL Test Report Test Methodology NSTL was provided the methodology to run each benchmark. The system was imaged before any testing was conducted to ensure that the file system was consistent throughout the testing. To change the configuration of the system from a Dual processor system to a single, the boot.ini file was edited using the /NUMPROC parameter. All applications and benchmarks were installed with default settings. Step by step procedures were given to NSTL by Dell, including all software and benchmarks needed to perform the testing. The Ansys benchmark was installed, by first installing the Ansys application. The Dell system was also setup as the Flexlm license server in both configurations. The Ansys57 benchmark, which can be obtained from the Ansys website, was extracted to its default location. For the single processor system, NSTL ran the ANSYS57bench_NP1.bat. ANSYS57bench_NP2.bat was run for the dual processor system. The benchmark was run three times for both configurations. Each system was rebooted between each run. The SPECcpu benchmark was loaded onto a clean system, and then run with the following commands: runspec -c dell.cpu2000.ic501.p4.15jan2002.cfg -r -u1 -Tall all (for the single processor setup compared to the dual system) runspec -c dell.cpu2000.ic501.p4.15jan2002.cfg -r -u2 -Tall all (for the dual processor setup) More information on this benchmark can be found at http://www.spec.org. The version of the Linpack benchmark used for the comparison was compiled with the Intel C compiler. The input parameters used were the number of tests (4), the problem sizes (1000, 2000, 3000, 4000), the leading dimensions (1000 2008 3000 4008), times to run the test (4, 4, 2, 1), and alignment values (4, 4, 4, 4). The alignment value is given in KB. The Adobe Photoshop benchmark was created by Dell. After Photoshop was installed, the operations (typical mix of Photoshop operations) were loaded. This ensured that the next time Photoshop was started, the predefined operations were performed. NSTL then ran benchmark using 150 MB and 300 MB files. The Memory and Image Cache was left at the default 50%. Before installing Sysmark benchmark, Direct X 8 was installed on the system. Then the Sysmark benchmark was installed. NSTL ran an Official Run with 3 Iterations on both the single and dual processor configurations. The system was rebooted after each iteration. Nastran was installed using default settings. The Flexlm was then installed locally. NSTL was provided with batch files that ran the following Nastran commands: nastran XXX.dat (for the single processor configuration); where XXX is the model name nastran XXX.dat nprocessors=2 parallel=2 (for the dual processor configuration); where XXX is the model name The model names that were used during testing can be found in the Results section.

    • NSTL Test Report Test Environment The Dell Precision 530 was configured with the following hardware: Processors: Dual/Single Intel® Xeon™ processors at 2.80 GHz Hard Drive Configuration: 2 x 36 GB 15000 RPM SCSI Drives (Set as 1 logical RAID 0 Drive) Memory: 2 GB ECC Memory Sound Card: Creative Labs Sound Blaster® Live! ™ PCI card Video Card: NVIDIA Quadro®4. 900XGL Graphics card Operating System: Microsoft® Windows® 2000 Professional NSTL 625 Ridge Pike, Conshohocken, PA 19428 Page 3 http://www.nstl.com/
    • NSTL Test Report Test Results SPEC CPU2000 Benchmark The SPEC CPU2000 benchmarks are used to measure the performance of the CPU, memory architecture, and compiler code generation. It is split up into two components. The first is the SPECint2000 which contains 12 benchmarks that perform integer computations written in C or C++. The second component is the SPECfp2000 which contains floating-point computations written in Fortran97, Fortran90, and C. The SPECcpu benchmark was loaded onto a clean system, and then run with the following commands: runspec -c dell.cpu2000.ic501.p4.15jan2002.cfg -r -u1 -Tall all (for the single processor setup compared to the dual system) runspec -c dell.cpu2000.ic501.p4.15jan2002.cfg -r -u2 -Tall all (for the dual processor setup) The configuration file used dell.cpu2000.ic501.p4.15jan2002.cfg was provided by Dell. The –u parameter specifies the number of users. The Tall tells the benchmark to run both the peak and base tests. The all parameter causes the benchmark to perform both the floating point and integer calculations. Table 1 displays the benchmarks that comprise the SPECint2000 benchmark as well as the Peak Ratio scores from the tests. The Peak Ratio allows the use of all compiler options to reduce time as much as possible.

This shows that the dual processor configuration performed 1.79 times better than the single processor configuration. The SPECfp_rate for the dual processor configuration was 14.5, while the SPECfp_rate for the single processor configuration was 10.1. According to these results the dual Intel® Xeon™ system performed 1.44 times better than the single Intel® Xeon™ system system. NSTL 625 Ridge Pike, Conshohocken, PA 19428 Page 4 http://www.nstl.com/

The performance difference increased as the size of the matrices increased. This implies that the dual configuration system can perform complex calculations at a faster rate than the single processor configuration. Ansys Benchmark Ansys/Multiphysics provides the ability to couple the effects of different types of physical phenomena and to study their impact on a design, creating more realistic simulations. It is a computer aided design program that takes into account many different real world physical situations in designing. As such, Ansys performs many complex floating point based analyses that stresses the processor, memory and hard disk subsystems. The Ansys benchmark performs linear and transient structural analysis on real-world models. It uses five different models: 1. Structural Linear Static Brick Frontal Medium 2. Structural Linear Static Brick PCG Medium 3. Structural Linear Static Shell Frontal Medium 4. Structural Linear Static Shell Frontal Small 5. Thermal Transient Nonlinear Brick Sparse Medium The measurements are made in user time, CPU time, and total elapsed system time. NSTL conducted three runs for each configuration. Better performance is indicated by a lower time. The total elapsed times for the benchmarks are displayed in Table 4. The Number/Real World Model columns correspond to the list described above.

Photoshop Benchmark Adobe Photoshop is a professional image-editing software application. The Photoshop benchmark is a Dell internally produced benchmark which uses Adobe Photoshop to perform some common time consuming tasks such as, resizing, Gaussian Blur, Lighting Effects, Unsharpen Mask, canvas rotation, Bas Relief, Watercolor, Extrude, Fragment, Difference Clouds, as well as loading and saving files. The benchmark runs the same tasks on single files of 100MB and 300MB and multiple files, NSTL 625 Ridge Pike, Conshohocken, PA 19428 Page 7 http://www.nstl.com/
    • NSTL Test Report three of 33MB and 100MB. The final test is an interaction test where three files of 33MB or 100MB are used to create a fourth large image. The interaction performs several copy and paste actions, works with multiple layers, including reordering and merging, and runs filters on different layers before adding some text, flattening the image, and embedding a watermark. NSTL ran the Photoshop benchmark three times for both configurations. Table 5 shows the results from the three runs.

Higher score is better The results of the Photoshop benchmark indicate that adding a second processor will increase performance. This means that the time the user is waiting for Photoshop to process transformations is decreased, thus improving efficiency. The dual processor configuration performed an average of 9% better on the 100MB Single File. A 12.5% increase in performance for the dual configuration was seen on the 100MB Multiple File Filters. The 100MB Multiple File Interaction showed a 5.5% increase in the performance by adding a second processor to the test system. The 300MB Single File, the 300MB Multiple File Filters, and the 300 MB Multiple File Interaction displayed a 8.6%, a 6.0%, and a 3.9% increase in performance, respectively, by adding a second processor.

    • NSTL Test Report The Photoshop benchmark also returns the exact time necessary to complete each transformation. It measures the time in seconds for over 80 different procedures. The steps vary from opening and saving files to editing images with filters. The dual Intel® Xeon™ system finished each run an average of ten minutes faster. Please refer to Table 6 for the actual times in seconds.

Sysmark 2002 Benchmark The Sysmark benchmark is made up of two distinct usage categories, Office productivity and an Internet Content Creation portion. The Office Productivity portion involves the creation and processing of documents using Microsoft Office XP, McAfee Virus scan v5.13, Dragon Naturally Speaking v5.0, WinZip 8.0, and Netscape Communicator 5.0. The Internet Content Creation half is comprised of the creation of web pages. The pages are created using Adobe Photoshop 6.01, Windows Media Encoder 7.1, Macromedia Dreamweaver 4.0, Macromedia Flash 5.0, and Adobe Premiere 6.0. The test is run at user speed with delays for key presses and mouse clicks, and each individual action response time is measured. Scores are based on a comparison of response times between the test system and a fixed calibration platform (Intel 815 Chipset, Pentium III 1.0 GHz). The results of the Sysmark benchmark show that the dual processor configuration has a higher rating than the single processor configuration. This implies that adding a second processor can greatly improve the performance of many office applications. The Internet Content Creation portion of the testing showed a 24% and a 9% increase in the Office productivity portion. Table 7 shows the results from the Sysmark benchmark, Dual Processor Ratings Single Processor Rating Internet 447 361 Run 1 Office 210 193 Internet 454 367 Run 2 Office 210 193 Internet 447 361 Run 3 Office 210 193 Internet 449 363 Average Office 210 193 Table 7 shows the results of the dual and single processor configurations for the Sysmark benchmark. Nastran 2001 Benchmark Nastran is a Computer aided engineering tool. The Nastran benchmark performs real-world analysis on models such as a cube, a cylinder, a transmission gear, and an engine block. The benchmark performs a static analysis of the cube model. It then conducts a resource prediction of a cylinder. Next it does a static analysis of an engine block containing super elements. The final test is conducted is a stress and deflective analysis of a transmission gear. The results are returned in system time, CPU time, and total elapsed time, thus lower numbers are better. The benchmark performs three runs on its own, and therefore, NSTL only ran the benchmark one time. Dell also provided smaller Nastran models to run with the benchmark. The smaller models are more processor intensive and can assist in illustrating the benefits of a dual processor configuration over a single processor configuration. The Lgast model, for example, finished 45% faster after adding a second processor to the test system. NSTL 625 Ridge Pike, Conshohocken, PA 19428 Page 9 http://www.nstl.com/

Higher number indicates a better score. As the results from the Fluent benchmarks illustrate, adding a second Intel® Xeon™ processor to the test system leads to a noticeable performance improvement. All of the benchmark models showed a significant increase in performance when the test system used both processors. There was a 27% increase in performance for the FL5S1 model. The FL5S2 and FL5S3 benchmark models showed an over 40% increase in performance with the second processor active. The FL5M1 and FL5M3 benchmarks showed a 37% and 47% increase in performance, respectively. The largest improvement was seen with the FL5M2 model, where the dual Intel® Xeon™ system performed 54% better than the single processor configuration. The results show as the models become more complex, the advantages of using a dual processor system over a single processor system become more evident. Figure 4 shows the average rating for the Fluent benchmark for the Single and Dual Processor configurations. NSTL 625 Ridge Pike, Conshohocken, PA 19428 Page 12 http://www.nstl.com/
    • NSTL Test Report Conclusion The benchmark testing conducted by NSTL, shows that adding a second Intel® Xeon™ to a computer system greatly improves performance. All of the benchmark results showed an improvement in the speed and performance of the applications. The SPECcpu benchmark, which measures CPU performance, displayed a 79% increase in the performance of the dual Intel® Xeon™ system over the single Intel® Xeon™ system. The Ansys benchmark performs linear and transient structural analysis on real-world models. This benchmark also showed a significant increase in performance by adding a second Intel® Xeon™ processor to the test system. The increase ranged from 22% up to 40% for the different sections of the benchmark. Adobe Photoshop also performed better on the dual processor system. The dual Intel® Xeon™ system finished an average of ten minutes faster than the single processor system on a mix of typical Photoshop operations. The Linpack benchmark measures the execution rate in MFLOPs (millions of floating point operations per second). NSTL testing showed that the dual Intel® Xeon™ system provides a 38% increase in performance over the single Intel® Xeon™ system. The increase in performance was proportional to the increase in the size of the matrices. The Fluent benchmark, which performs complex calculations to obtain flow rates for various models, showed a significant increase in performance when run on the dual processor configuration. The performance increases ranged from 27% to as high as 54% better on the dual Intel® Xeon™ system. The final benchmark NSTL conducted was the Sysmark benchmark which measures performance using a mix of applications in a multitasking environment. The results of the Sysmark benchmark show that adding a second processor to the test system in multitasking environments improved the performance of office applications by 8% and internet content creation by 24%. NSTL testing showed that for all the benchmarks, the dual processor configuration showed better performance than the single processor configuration, thus reducing the time needed for an end-user to complete their task more efficiently.
