چکیده

Intelligent Resource Director (IRD), a feature of the IBM eServer zSeries processors and the z/OS operating system, manages multiple heterogeneous workloads with various business priorities toward achieving their goals. It establishes a more synergistic relationship with the Workload Manager (WLM) component of z/OS and the zSeries hardware, and augments the adjustments that WLM makes to local sysplex members by managing the set of logical partitions on a particular central processing complex (CPC) that are part of the same sysplex, known as a logically partitioned (LPAR) cluster. This paper describes the three primary areas that IRD manages: LPAR CPU management, channel subsystem priority queueing (CSSPQ), and dynamic channel path management (DCM).

Priority-Aware Near-Optimal Scheduling for Heterogeneous Multi-Core Systems with Specialized Accelerators

To deliver high performance in power limited systems, architects have turned to using heterogeneous systems, either CPU+GPU or mixed CPU-hardware systems. However, in systems with different processor types and task affinities, scheduling tasks becomes more challenging than in homogeneous multi-core systems or systems without task affinities. The problem is even more complex when specialized acc...

Proposed Feature Selection for Dynamic Thermal Management in Multicore Systems

Increasing the number of cores in order to the demand of more computing power has led to increasing the processor temperature of a multi-core system. One of the main approaches for reducing temperature is the dynamic thermal management techniques. These methods divided into two classes, reactive and proactive. Proactive methods manage the processor temperature, by forecasting the temperature be...

An interactive interface and RT-Mach support for monitoring and controlling resource management

Real-time applications in dynamic systems such as multimedia systems may change their timing characteristics on the fly and may be created and terminated at any time. A priori resource allocation decisions may not hold throughout the lifetime of such applications because of changing user needs and interests. The ability to monitor and control system resources dynamically is fundamental to build...

An Experimental Investigation of the Potential of BLF-driven Scheduling of Real-time Threads

Resource allocation in complex real-time computer systems (RTCS’s) cannot be adequately handled by straightforward extensions of the CPU and peripheral device scheduling techniques used in non-RTCS’s. Rather, all the resources including CPU’s, peripheral devices, communication channels, etc. should be handled in an integrated manner. As an idealistic framework, we laid out a globally optimal re...
