You were directed here by an Error Condition listed in Table 1-6 on page 1-19which lists functional problems reported in /var/adm/SPlogs/css0/p0/out.top file. This file lists all switch data connections with comment lines indicating the various types.

1.Check the entire /var/adm/SPlogs/css0/p0/out.top file for errors before proceeding to the prioritized table.

2.Use the following prioritized table to service problems reported in the /var/adm/SPlogs/css0/p0/out.top file. The messages are from comment lines preceding the error.

Notes:

a.Be aware that wrap plugs or terminators used in the following steps can potentially fail; therefore, exercise caution before performing major replacements to make sure that a diagnostic wrap plug or terminator is not faulty.

b.Where applicable, frame and switch assembly jack numbers are indicated on each line of the out.top file. (Refer to ªFormat structureº on page 2-1 for more information on the nomenclature.)

For example:

E02-S17-BH-J18

Identifies the switch in frame 2, slot 17 using bulkhead jack 18

E02-N05

Identifies node in frame 2, slot 5

E06-S02-BH-J3

Identifies multi-switch frame 6, slot 2, BH-J3

Refer to notes at beginning of ªSwitch function (MAP 0620)º on page 1-17 for more information on cable connections and logical-to-physical frame translations.

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.
