-1. INTRODUCTION:
-
-General-purpose GPU architectures are becoming increasingly prevalent in
-mainstream computing, and as such they require judicious optimization for
-energy efficiency. To enable such research, we propose a new GPU power model
-that offers flexibility, adaptability, and stability. Flexibility is achieved
-by using a bottom-up methodology and abstracting parameters from the
-microarchitectural components as model inputs. Adaptability ensures that both
-program and microarchitectural level interactions are captured during
-execution, thereby enabling new power-management techniques specifically
-targeted at GPUs. Stability is examined by validating the power model against
-measurements of two commercial GPUs comprehensively through the leakage power,
-average dynamic power, and dynamic power trace. The measured error is within
-9.7% and 13.6% across our evaluated benchmark suite for the two target GPUs
-(GTX 480 and Quadro FX 5600 respectively) and the model accurately tracks the
-relative power consumption trend over time.
-
-The power model modifies and extends the McPAT CPU power model simulator to
-model the power of contemporary GPGPUs and drive the modified McPAT version
-with a cycle-accurate simulator, GPGPU-Sim. 
-
-2. Using the Power Model 
-2.1 Compiling the Power Model
-
-By default, GPGPU-Sim bypasses the McPAT compilation. Hence, it is not
-necessary to install our modified McPAT along with GPGPU-Sim. However, if the
-power model is required, our modified version of McPAT will be compiled
-alongside GPGPU-Sim into libcudart.so.
-
-The location of McPAT is specified by the GPGPUSIM_POWER_MODEL environment
-variable and is used in GPGPU-Sim's Makefile to compile McPAT. This can either
-be set manually or automatically set by the setup_evironment.sh file in
-<GPGPU-Sim>/distribution if McPAT is found in the default directory
-(<GPGPU-Sim>/mcpat/).
-
-2.2. Configuration Options
-
-This sections lists the most relevant configuration options either to describe
-model a specific architecture, model a certain improvement, or to produce extra
-data from the simulation. Some of these configurations are set in the GPGPU-Sim
-config files and others will be set in the McPAT XML configuration files.
-GPGPU-Sim configurations mainly force specific changes to the performance
-modeling itself or the output format of data, while McPAT configurations mainly
-determine specific parameters for the different architectural components that
-are reflected in the power modeling of these components. Here, we metion only
-GPGPUsim cofigurations:
-
-1- power_simulation_enabled: Enablle the power model simulator; if enabled, an
-output file is genarated to include the detailed Power coefficients for the
-simulated configuration and the Average/Maximum/Minimum total power breakdowns
-for each kernel.
-
-2- mcpat_xml_file: The McPAT XML configuration file name; by default it is
-mcpat.xml.
-
-3- gpu_stat_sample_frequency: Determines the sampling frequency used in the
-power calculations, the performance counters are reset before each samples and
-accumulated during the sampling period, and finaly passed to the power model
-(McPAT) at the end of each sample.
-
-4- power_trace_enabled: If enabled, it produces two output files that details
-the power breakdown values, and the accumulative performance counters values
-for each sample.
-
-5- power_per_cycle_dump: Dump detailed power data each sample
-
-6- steady_power_levels_enabled: 	If enabled, it tracks the steady state
-power level throughout the execution and report the start/end values with the
-average power recorded for each componenet. The steady state is determined by
-(-steady_state_definition) option.
-
-7- steady_state_definition: Takes two values. First value detemines the allowed
-deviation within the steady state and the second value determines minimum
-number of samples required to assume this is a steady state power level.
-
-
-3. Understanding Simulation Output
-
-In this section, we detail the fromat of the power simulator output. By
-default, if the power simulation is enabled at least one output file that
-reports the average/maximum/minimum power values for each kernel is produced.
-More outputs can be enabled if the corresponding configurations is enabled. 
-
-
-1- gpgpusim_power_report_(date&time).log- Requires (-power_simulation_enabled
-1):  	Includes the detailed power coefficients for this configuration and the
-Average/Maximum/Minimum total power and their breakdowns for the different
-components for each kernel
-
-2- gpgpusim_power_trace_(date&time).log.gz- Requires (-power_trace_enabled 1):
-A compressed file that has a detailed average power breakdown trace in a comma
-separated format
-
-3- gpgpusim_metric_trace_(date&time).log.gz- Requires (-power_trace_enabled 1):
-A compressed file that has a detailed performance counters trace in a comma
-separated format
-
-4- gpgpusim_steady_state_tracking_report_(date&time).log.gz- Requires
-(-steady_power_levels_enabled 1): It rports the steady state power level
-throughout the execution with the start/end values of each interval and the
-average power recorded for each componenet during this interval in a comma
-separated format

-5. Software Design of the Power Model
-
-This section presents the software design of the power model.
-
-5.1. File list and brief description
-
-In this section, we briefly describe the files that were added to interface
-GPGPU-Sim with McPAT. 
-
-
-1- power_stat.cc/h @ <GPGPU_SIM>/distribution/src/gpgpu-sim/: 	These files
-contain the main structures used for recording GPGPU-Sim performance counters:
-power_core_stat_t (for all core related counters) and power_mem_stat_t (for all
-memory related counters), which are contained in the wrapper power_stat_t
-object. The core and mem stat structures contain multiple counter pointer
-arrays with 2 locations per counter (e.g. unsigned *m_counter[2]): [0] ->
-pointer to counter with the current value, [1] -> previous sampled value. The
-difference, [0]-[1], is used to get the per-sample estimated power in McPAT.
-
-2- gpgpu_sim_wrapper.cc/h @ <GPGPU_SIM>/mcpat/: These files contain the
-gpgpu_sim_wrapper class that contains all of the McPAT structures (such as
-Processor, ParseXML, etc), manages the power output files, and passes the
-GPGPU-Sim performance counters (described in power_stat.cc/h (1)) into McPAT.
-The gpgpu_sim_wrapper structure is used in power_interface.cc/h (3) to separate
-the McPAT structures and interface from GPGPU-Sim.
-
-3- power_interface.cc/h @ <GPGPU_SIM>/distribution/src/gpgpu-sim/: These files
-are used to interface GPGPU-Sim with McPAT via two main functions: init_mcpat()
-and mcpat_cycle(). init_mcpat() is called from gpgpu_sim::init() in gpu-sim.cc
-and through the gpgpu_sim_wrapper object, initializes all of the power related
-structures in GPGPU-Sim and McPAT. Similarly, mcpat_cycle() is called from
-gpgpu_sim::cycle() in gpu-sim.cc, which passes all of the performance counters
-to McPAT (through the gpgpu_sim_wrapper object).
-
-4- gpgpu_sim.verify @ <GPGPU_SIM>/mcpat/: This file is distributed with our
-modified version of McPAT to ensure the correct McPAT version is used with
-GPGPU-Sim
