Problems solved by technology

However, since a direct connection between the interconnection network and the processor cannot be guaranteed, alternate mechanisms are often used for this communication
[0005] The use of processors for seeking and retrieving fault information and the further use of alternative mechanisms for retrieving fault information when faults occur in an interconnected network are not as effective as expected

Embodiment Construction

[0021] In accordance with the principles of the present invention, a reporting capability is provided wherein hardware elements of a distributed computer system report error conditions to a designated processing node in the computer system. Hardware components report errors without software or processor logic.

[0022] figure 1 An example of a distributed computer system including and using the reporting capabilities of the present invention is described in . In one embodiment, the distributed computer system is a RISC System / 6000 Scalable Power Parallel System offered by IBM Corporation and includes a large number of processing nodes 102 connected to an interconnection network 104 . An example of processing nodes and interconnection network is described below.

[0023] A processing node includes, for example, a processor 106, such as the RS / 6000 processor provided by IBM Corporation, and a communication adapter 108, which is connected to the processor via, for example, a sy...

Abstract

An error message is generated by a hardware element of a distributed computer system when an error is detected. Error information is then forwarded from the hardware element to one or more designated processing nodes of the distributed computer system. Hardware elements include, for example, a switching element or a communication adapter adapted to report detected errors.

Description

technical field [0001] The present invention relates generally to distributed computer systems, and more particularly to using hardware components of these systems to report errors found by the hardware components. Background technique [0002] This application includes subject matter related to that of the following application, assigned to the same assignee as this application and filed on the same date as this application. The applications listed below are hereby incorporated by reference in their entirety. [0003] "System for Reporting Errors by a Hardware Element of a Distributed Computer System," by Desnoyers et al., Serial No. 08 / 838,389 , (abstract number PO9-97-045). Typically, a distributed computer system includes a large number of processors interconnected by an interconnection network. One of these processors has the task of monitoring the computer system for device failures. For example, use a heart-beating protocol to periodically poll each device in the ...
