7 Key Steps To Building High Performance Systems

Step 3: Making the decision—32-bit vs. 64-bit
It wasn't a slam-dunk decision to go with a 64-bit version of Windows Vista. For all the progress that the Windows ecosystem has made in building out driver support, application support and stability for the OS' 64-bit version, it's still supported much, much less than 32-bit Windows Vista. Were we only to require a workstation for tasks like document imaging and light amounts of 3-D mapping and some video rendering, staying with a 32-bit platform would have been fine. However, CAD, robust 3-D design and other HPC applications are often optimized for 64-bit computing, so we opted to move up to Windows Vista 64-bit.

There are several points worth noting. For starters, Microsoft has reported that as many as 20 percent of all new Windows Vista PCs that sign up for Windows Update are 64-bit systems; for another, driver support is, in fact, slowly improving. Windows Vista 64-bit was a quick install. The software we deployed for testing all supported 64-bit computing, so we were able to get a cursory feel for the power of a higher-end workstation solution.

Step 4: One last check. Do we really need a workstation?
We've been very impressed this year by both the speed and performance of quad-core PCs built on technology by both Intel and Advanced Micro Devices, as well as the systems' ability to give Windows Vista (32-bit or 64-bit) the head room needed to get real work done. The one limitation we've lamented is that those systems max out with 4 GB of RAM both because the 32-bit versions of the OS as well as the base configurations, including motherboards, usually support only up to 4 GB of memory. Many system builders, solution providers and their customers have found out the hard way the pain of memory limitations. With the ASUS motherboard, which supports up to 16 GB of RAM, that wouldn't be an issue for any workload, big or small. Where hardware limitations can mean time and money, workstations, in fact, could be an effective way to handle it.

Step 5: Building the system
Everything snapped together just fine. But we learned—sort of the hard way—that when building our own dual-CPU workstation, airflow isn't to be taken lightly. Based on other workstations and servers we've put together ourselves, we took a chance that the system would be just fine with two passive heat sinks over the CPUs and a powerful fan built into the chassis with lots of room for airflow. It was a chance that worked against us; within minutes, the CPUs overheated and the system shut down. We took the heat sinks out and replaced them with CPU fans. Since the ASUS board came with integrated Intel graphics and audio, there wasn't much else to worry about. The HDD and optical drives were a snap to install in the Antec case, which came prebuilt with a 650-watt power supply.

Step 6: Fine-Tuning
Trying to install a couple of simple applications with 3-D rendering threw us a curveball. The integrated video and graphics that came with the ASUS board could not enter into hardware acceleration mode, which was a requirement for an application as simple as Microsoft Virtual Earth in 3-D mode. The problem was solved by adding the Nvidia eGeForce 8400 GS card, downloading and installing the drivers and rebooting. Along the way, we needed to disable the onboard video by shutting off the on-board jumper. It immediately fixed the problem, hiking the Geekbench score to 6097.

Step 7: Mapping an upgrade path
Because it was a custom-build, this system could be upgraded for such things as memory (it's expandable to 16 GB), hard drive storage and video. As this is a relatively early stage in the ecosystem buildout for Windows Vista 64-bit, there's a good chance that systems can be delivered with enough head room in the hardware asset itself to scale up with the customers for two to three years.

Bottom line
Higher-performing workstations demand a little more TLC during the planning, design and building than a simple office PC. However, given the potential to improve customer productivity, provide scalability and system builder/VAR margin, we believe the building blocks, software and opportunity are there now to begin having the conversation with partners and customers about delivering desktop HPCs in scenarios where they may not have previously provided value for them.
