ECA192

 

 

Note: The ECA192 instructions differ from the above and are included with the ECA192 Package.

Note: This procedure is similar to that used for performing software updates (PTF's) to SP nodes. You can Refer to ªPerforming Software Maintenanceº inParallel System Support Programs for AIX: Installation and Migration Guide, GA22-7347, for a general idea of how to perform the installation.

1.Locate the diskette (either shipped with your adapter or obtained from the TOOLS disk.

2.Copy the adapter microcode to a temporary directory on the control workstation:

a.Insert the diskette in the control workstation diskette drive

b.Log on as root.

c.Select a name in a temporary directory to store the microcode image such as ª/tmp/microcodeº or

ª/tmp/esconº

d.

bffcreate -l -d /dev/fd0

This will list the contents of the diskette. Record the package name results (for example, escon.cuu). This will be useful if you decide to store other adapter microcode in the same directory.

e.

bffcreate -t /tmp/microcode -d /dev/fd0 all

This will copy the data to the designated directory and update a table of contents file (.toc)

3.NFS Export that directory to the nodes: exportfs -i /tmp/microcode

4.Either use the dsh command to control one or more nodes directly from the control workstation, or telnet to each individual node. (Commands in following steps would be executes as in the example, but without the ªdshº prefix)

Note: Refer to IBM RS/6000 SP: Administration Guide for help on using dsh.

5.

dsh -a "umount /mnt"

6.

dsh -a "mount <control wks>:/tmp/microcode /mnt"

7.

dsh -a "installp -qacXd /mnt all"

The ªallº can be replaced by the individual microcode package as recorded earlier.

8.

dsh -a "umount /mnt"

9.

exportfs -u /tmp/microcode

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.
