Event: Tenth Annual Workshop for the Energy Efficient HPC Working Group (EE HPC WG)

Date/Time: Monday, November 18th 9:00AM-5:30PM, Room 507, SC19 Denver, Colorado USA

Location: Denver, Colorado USA

 

ABSTRACT:

 

Despite significant pressure on both Moore’s Law and Dennard scaling, the appetite for ever larger systems continues to grow. Computing trends, in terms of highly optimized hardware platforms that may leverage accelerators or other non-traditional components, scalable and highly performing applications, and the requirements to manage exponentially larger data sets are driving facility demands not envisioned just a few years ago. The facility demands for supercomputing centers (SCs) are characterized by electrical power demands for computing systems that scale to tens of megawatts (MW) and millisecond voltage fluctuations approaching 10MW for the largest systems. The demand for primary electrical distribution capabilities to current large-scale facilities can exceed 60MW. The operational costs of these facilities must be balanced versus the demand from the systems owners and users for high availability, high utilization, and low-impact facility maintenance and service demands. To achieve this balance, many SCs continue to innovate their operational design practices and technologies.

 

The workshop for the Energy Efficient HPC Working Group brings together those concerned with HPC energy efficiency and energy conservation of both HPC systems and facilities. The annual workshop has a broad scope of energy efficiency in HPC ranging from silicon and components, through platform integration, software, and firmware and up to the data center, facility, and connection to the utility provider. Because of this broad scope, we engage a wide spectrum of participants- both facilities and operationally focused people as well as computer engineers and architects- which enhances the discussions and sharing that occurs.

Special Issue on "Performance, Power and Energy-Efficiency Optimization in Computer Architectures"

Energies, MDPI (ISSN 1996-1073) - Open Access Journal

SCOPE AND OBJECTIVES:

 

To satisfy the growing demands for higher application performance and reduced power and energy consumption, performance and energy efficiency optimization has become a fundamental constraint and requisite, embracing the processor architectures (homogeneous/heterogeneous

many-core GPPs), the accelerators and co-processors (e.g., APUs, GPUs, etc.), and even the embedded domain (e.g., SoCs, FPGAs, ASICs, etc.), where the development of energy-saving methodologies is a fundamental issue  not only  for mobile, hand-held and wireless applications but also to reach exascale computing.

 

The need to satisfy the required performance levels, as well as the new thermal, power and energy constraints, require the definition of innovative solutions to attain an effective optimization of the offered throughput and/or minimization of the power/energy consumption. Among

many other research directions, this challenge naturally involves the design of high performance and energy-efficient architectures and communication infrastructures, as well as the development of novel algorithms and tools comprising the scheduling, mapping, load-balancing, and scalability, together with innovative compilation techniques.

 

The goal of this Special Issue is to collect novel contributions covering prevailing issues and prominent challenges related to optimizing the performance, power, and energy efficiency in computing devices and systems.

 

Topics of interest include (but are not limited to) the following:

 

• Computer architecture trends for performance and energy efficiency:

•  ISA diversity and morphable structures;
•  Run-time reconfiguration/adaptation and dynamic scalability;

• CPU accelerator co-design (GPUs, APUs, FPGAs, etc.);

• Heterogeneous and parallel processing architectures;

• Approximate computing techniques and architectures;

• • Neuromorphic architectures.

• Energy/power management and control:

•  Run-time power/energy monitoring and sensing;

• Performance, power, energy and heat/temperature modeling;

• Dynamic Voltage and Frequency Scaling (DVFS);

• Power/clock gating strategies;

• Performance vs. power/energy scaling and management.

• • Tools and algorithms:

• Programming languages, compilers and models for energy-aware computing;

• Profiling and simulation tools for heat/power/energy estimation;

• Scheduling, mapping and task/thread migration policies for performance and power/energy optimization;

• Performance- and energy-aware resource management;

• Operating system support and energy management tools.
