“…Balakrishnan and Solihin [3] proposed collecting the temporal reuse pattern of memory accesses using the stack distance profile. The study demonstrated close match in miss rates between the generated clones compared to the original applications, across cache sizes, associativities, write policies, and number of hierarchy levels.…”

While customizing the memory system design or picking the most fitting design for applications is very critical, many software vendors refrain from releasing their software for several reasons. First, many applications are proprietary, hence releasing them to hardware architects or vendors is not desired. Second, applications such as defense and nuclear simulations are very sensitive, hence accessing them is very restricted. Nonetheless, customizing the hardware for such applications is still important and highly desired. Workload cloning is the technique of generating synthetic clones from the original workload. The clones mimic the memory access behavior of the original workloads, hence enable exploring the design space with high level of accuracy. In this article, we survey the state-of-art cloning techniques of the memory access behavior and their uses.

“…Fortunately, several black-box cloning techniques have demonstrated high level of accuracy in capturing different aspects of the memory behavior. For this paper, we will give a brief overview of the state-of-art cloning techniques: STM [2], [23], MeToo [23], [24] and MEMST [4], and describe STM in more details.…”

“…The number of frameworks proposed since then has been growing continuously corroborating their importance for the community. In contrast to our adaptive framework, particular solutions -without the micro-architecture semantics of MicroProbewere developed for different purposes: to generate synthetic microbenchmarks [2][3][4]26], to be able to reproduce proprietary application behavior [30,32], to perform architecture explorations [31], to generate power or reliability stress tests [20,21,33,39], to evaluate energy efficiency of systems [13], or to model cache behavior [1].…”

“…In particular, three different characterization queries are illustrated in this paper. MicroProbe's automated generation facility is used to derive: (a) an accurate and decomposable power model that is used to project the power consumption for arbitrary CMP/SMT workloads; (b) energy-per-instruction (EPI) ratings for different instruction classes supported by the system; and (c) a systematically generated synthetic stress test that maximizes power consumption for the targeted system 1 . Experimental results are measured on a POWER7-based 8-core/32-thread system [42] in order to validate the efficacy of MicroProbe.…”

Microprocessor-based systems today are composed of multi-core, multi-threaded processors with complex cache hierarchies and gigabytes of main memory. Accurate characterization of such a system, through predictive pre-silicon modeling and/or diagnostic postsilicon measurement based analysis are increasingly cumbersome and error prone. This is especially true of energy-related characterization studies. In this paper, we take the position that automated micro-benchmarks generated with particular objectives in mind hold the key to obtaining accurate energy-related characterization. As such, we first present a flexible micro-benchmark generation framework (MicroProbe) that is used to probe complex multi-core/multithreaded systems with a variety and range of energy-related queries in mind. We then present experimental results centered around an IBM POWER7 CMP/SMT system to demonstrate how the systematically generated micro-benchmarks can be used to answer three specific queries: (a) How to project application-specific (and if needed, phase-specific) power consumption with component-wise breakdowns? (b) How to measure energy-per-instruction (EPI) values for the target machine? (c) How to bound the worst-case (maximum) power consumption in order to determine safe, but practical (i.e. affordable) packaging or cooling solutions? The solution approaches to the above problems are all new. Hardware measurement based analysis shows superior power projection accuracy (with error margins of less than 2.3% across SPEC CPU2006) as well as maxpower stressing capability (with 10.7% increase in processor power over the very worst-case power seen during the execution of SPEC CPU2006 applications).
