Embodiment Construction

[0012] Referring now to the drawings, in particular, to figure 1 , which depicts a block diagram of a data processing system in which the present invention may be implemented. Data processing system 100 includes central electronics complex 101 that includes logically partitioned hardware. CEC 101 includes a plurality of processors 102 , 103 , 104 and 105 connected to system bus 106 . Alternatively, a single processor system can also be used. Also connected to system bus 106 is memory controller / cache 108, which provides an interface to a plurality of local memories 160-163. RIO hub 110 is connected to system bus 106 and provides an interface to RIO bus 112 . Memory controller / cache 108 and RIO hub 110 may also be integrated as described herein.

[0013] Data processing system 100 is a logically partitioned data processing system. As such, data processing system 100 may have multiple heterogeneous operating systems (or multiple instances of a single operating system) runni...

Abstract

A non-invasive method, system, and computer product for monitoring I / O performance without using the RIO bus. When executing a performance benchmark run in a remote I / O drawer, the system logs into a bulk power controller, wherein the bulk power controller provides a communications path between the data processing system and the I / O drawer, and wherein the communications path allows the data processing system to access chip register information on the I / O drawer without using a RIO link. Using the communications path, the system may monitor I / O performance and obtain chip register information. The system may further increase performance by using software to detect a load imbalance. Through the communications path, the software is able to dynamically balance the load by changing the chip register settings to allow the initialization registers to handle the load more efficiently.

Description

technical field [0001] Generally, the present invention relates to an improved data processing system, and more particularly, to a method, apparatus and computer product for performance monitoring in a data processing system. In particular, the present invention provides methods, systems and computer products that do not require the use of remote input / output (RIO) cables to monitor input / output (I / O) performance. Background technique [0002] A multiprocessor data processing system is a data processing system that contains multiple central processing units. The system allows for logical partitioning, wherein a single multiprocessor data processing system can operate as if the system were two or more independent systems. In such a system, each logical partition represents a division of resources in the system and operates as an independent logical system. Each of these partitions is logical because the division of resources can be physical or virtual. For example, a multi...
