From: Adam Hammouda <ahammouda(a)cs.uchicago.edu> Energy Savings and Performance Optimizations With Pliable Algorithms on Intel’s E5-2699v3 (Haswell) Nodes Adam Hammouda, Andrew Siegel, Pete Beckman MCS The goal of our research is to study operating system design decisions for next generation HPC architectures. In particular, we aim to study the impact which those decisions have on application performance characteristics. Further, we aim to understand how these decisions and performance characteristics relate to the thermal stability and energy effeciency of the architecture in question. Broad questions of interest to our research include the following: • Is there a layer of the HPC runtime environment best equipped for mitigating thermal load imbalances (i.e. OS, runtime system, or application)? • If it is more optimal to share these responsibilities between layers, what is the optimal division of labor? • What are the best metrics for the above referenced optimality? • With such metrics, what are acceptable tradeoffs between performance and energy? • What are generalizable strategies for the application layer to handle thermal load imbalances? What is a generalizable strategy for the application layer to receive and share information with the runtime system? In an earlier work, we reformulated an algorithm class of bulk-synchronous computation to account for nonuniformities in process execution rates. The challenge of energy and thermal efficiency presented by next generation machines is precisely what motivated our algorithmic developments in this previous work. The COOLR project presents an opportunity to pursue this line of inquiry even further by exploring the precise characteristics of these anticipated nonuniformities. To this end we have already begun our explorations of the Intel Xeon E5-2670 machine available to us. We are exploring the effects of per-socket controls over cpu frequency, and pstate setings, and we have developed metrics to quantify the tradeoffs in performance and thermal load balance. However, our algorithmic work in Hammouda and Siegel 2013 was designed to exploit per-process nonuniformities in execution rates, and we therefore could benefit greatly from a machine which provides access to these controls. COOLR, CESAR Northwestern Adam Hammouda, Kaicheng Zhang (Northwestern) E5-2699v3 (Haswell) nodes (http://ark.intel.com/products/81061/Intel-Xeon-Processor-E5-2699-v3-45M-Cac…) In particular, we would like isolated and IPMI access to change BIOS. Such access would allow us to explore the per-process strategies for thermal load balancing, and the subsequently necessary application optimization.

Hi Ginny, Can you please remove the Kayla entry on the JLSE hardware page? Rosie succeeds this hardware so I haven't been keeping it running. Thanks, Ben

From: Vitali Morozov <morozov(a)anl.gov> ALCF Benchmarking and Performance Comparisons Vitali Morozov Argonne Leadership Computing Facility When building a new supercomputer, the diversity of available hardware components is making very challenging to make proper design choices and keep the right balance between them. Developing a piece of hardware, that universally fits all general purpose application needs has been proven infeasible and the design choice is usually made based on study and analysis of a workload that the supercomputer center is expected to run on a new machine. At ALCF, we are working on a set of benchmarks, that target the majority of perspective pieces of hardware and we collect statistics on how different hardware responds to different workloads. The benchmarks are covering a diverse set of ALCF workloads, starting from the kernels that exercise only one hardware feature at a time (vectorization benchmark, streaming data, staging memory, caching hierarchy), to the mini-applications that contain a simplified version of a realistic workload, to the full applications that are running on ALCF p roduction resource. We will be using the diversity of JLSE hardware resources to improve our knowledge database on available hardware features and see their responses on the ALCF workloads. We plan to use this knowledge on developing the lessons learned and good programming practices for utilizing these features in real world on ALCF production resources.

From: Vitali Morozov <morozov(a)anl.gov> SKOPE - SKeleton for wOrkload Performance Exploration Vitali Morozov Argonne Leadership Computing Facility ALCF continues to develop a performance analysis, tuning, and projection framework named SKOPE - SKeleton for wOrkload Performance Exploration. Understanding a workload behaviour has already become a critical step in performance studies; it plays an important role in the design and adoption of new algorithms and hardware. SKOPE provides an abstract language for algorithmic description of a workload, a framework for internal representation the workload, an API to describe the target hardware platform, a set of tools to develop performance analysis and generate performance projection of a workload on a given platform, and a tool to allow for transformation of the workload to better fit into the hardware. DOE University of Chicago We will be using a diversity of computer architectures and memory subsystems for ALCF workload performance analysis and explorations.

From: Kazutomo Yoshii <kazutomo(a)mcs.anl.gov> Investigating thermal and power characteristics of the Haswell processors Kazutomo Yoshii Kazutomo Yoshii We will explore new features in Intel Haswell processors that particularly affects thermal and power behavior, which will create the performance variability. Its fully integrated voltage regulator (FIVR) will provide lower switching latencies and finer granularity than before, however, FIVR itself also becomes a possible heat source. Its turboboost, which is a thermal-aware mechanism, poses a new challenge: the gap between the TDP frequency and the turboboost frequency is more than 1 GHz on some model, and the frequency range for FPU intensive workloads is introduced. We will port our thermal and power monitoring software for Haswell and explore new control features introduced in Haswell.
