Switch Function (MAP 0620)

b.Go to ″Processor node diagnostics and descriptions (MAP 0130)″ in RS/6000 SP: System Service Guide to fix problem.

Step 0620-011

The Power (green) LED is lit, indicating the processor node is powered on.

1.Run advanced diagnostics in service mode on device ªcssXº (where X=0 or 1) on this processor node and its associated switch port. Refer to:

v ªRunning diagnostics on a switch portº on page 3-12.

v″Running diagnostics in a processor node″ in RS/6000 SP: System Service Guide

Notes:

a.Advanced cable wrap tests will not run successfully for 10-, 15-, and 20-meter SP Switch2 data cables. If these data cables are used, swap or change the suspected cable.

b.Advanced ªcssXº (where X=0 or 1) diagnostics will require a male and a female wrap plug to perform the card wrap and cable wrap tests. When testing the SP Switch2 adapter, the cable associated with the male and female wrap plugs included in the ship group must be used to perform card diagnostics (refer to RS/6000 SP: System Service Guide).

c.If unable to run diagnostics, make certain the adapter is configured correctly.

d.If the adapter is configured correctly and diagnostics fail, replace the card.

2.Do you get a Service Request Number (SRN) from ªcssXº (where X=0 or 1) diagnostics? v If yes:

a.An SRN was obtained from diagnostics.

b.Use the following SRN table (Table 1-8)to continue service.

c.After using Table 1-8,go to ªStep 0620-012º on page 1-25.

vIf no:

a.The diagnostics did not detect a problem, therefore the problem is in switch assembly.

b.Go to ªStep 0620-020º on page 1-27.

RS/6000 SP specifications

The IBM RS/6000 SP (Scalable Power) is a high-performance computing system that was developed in the early 1990s and has since become a significant player in the realm of supercomputing and enterprise solutions. Designed primarily for scientific, engineering, and complex data analysis tasks, the RS/6000 SP provides powerful processing capabilities, enhanced scalability, and features to support demanding applications.

One of the key characteristics of the RS/6000 SP is its modular architecture, which allows for the addition of multiple nodes. Each node is based on IBM's Power architecture, leveraging the RISC (Reduced Instruction Set Computing) design to achieve high throughput and efficiency. The system can support configurations ranging from a few nodes to hundreds, enabling organizations to scale their computational power as needed based on workload requirements.

The RS/6000 SP employs advanced interconnect technologies, most notably the SP Switch, which ensures high-speed communication between nodes. This interconnect allows for seamless data transfer, ensuring that the system can handle large datasets and complex computations without bottlenecks. The SP's ability to deliver concurrent processing capabilities makes it ideal for parallel computing tasks, including simulations, modeling, and large-scale computations.

In terms of software, the RS/6000 SP was equipped with AIX, IBM's version of the UNIX operating system, which provides a stable and secure environment for enterprise applications. Furthermore, the system supports a vast array of programming languages and tools, including Fortran, C, and C++, along with libraries and frameworks designed for high-performance computing. This compatibility allows developers to optimize their applications to fully utilize the underlying hardware.

Another notable feature of the RS/6000 SP is its extensive support for various workloads, including database management, multi-user applications, and graphical processing. The system was equipped with high-performance graphics capabilities, making it suitable for tasks that require intensive visualization, such as computer-aided design (CAD) and scientific visualization.

Overall, the IBM RS/6000 SP has solidified its role in the high-performance computing landscape, combining advanced technologies, robust scalability, and flexibility to meet the unique demands of research and enterprise environments. Its legacy continues to influence modern computing architectures, embodying IBM’s commitment to innovation and performance in the pursuit of complex problem-solving capabilities.
