Tune Up Utilities 2012
Su Strawderman
Did you know that your central air conditioner may lose up to 5% of its original efficiency every year? That can increase your electric bill, shorten the life of your equipment, and reduce the comfort level in your home.
A simple inspection and tune-up of your central air conditioner can keep it running efficiently and save you money. An incentive is available to customers with central air conditioners no larger than five (5) tons and those who have not received a tune-up within the past three years. To receive the cash incentive, a tune-up of the central air conditioner must be performed by a professional service technician and include a 12-point inspection. The tune-up will not only help the central air conditioner cool more efficiently but will also improve its ability to dehumidify properly.

If you are eligible, you may receive one regular HEAP benefit per program year and could also be eligible for emergency HEAP benefits if you are in danger of running out of fuel or having your utility service shut off.
Tier I eligibility is based on gross income and household size, on the date of application the household's gross income must be at or below 130% of federal poverty level for the household size; or at least one adult household member must be in receipt of ongoing assistance through Temporary Assistance (TA), Supplemental Nutrition Assistance Program (SNAP) or code A SSI.
If you are a homeowner and eligible, the Heating Equipment Repair and Replacement benefit can help you repair or replace your furnace, boiler and other direct heating equipment necessary to keep your home's primary heating source working.
You may call your HEAP Local District Contact to apply. An eligibility interview is required for all HERR applications but may be completed with applicants in person or by telephone. Your local district contact will decide if you meet all the eligibility conditions, including the income and resource requirements. The district will provide more information on how to submit the application and required documentation.
Eligible households can receive energy efficiency services, which includes the cleaning of primary heating equipment, but may also include chimney cleaning, minor repairs, installation of carbon monoxide detectors or programmable thermostats, if needed, to allow for the safe, proper and efficient operation of the heating equipment. Benefit amounts are based on the actual cost incurred to provide clean and tune services, up to a maximum of $500. No additional HEAP cash benefits are available.
Only one air conditioner or fan, not to exceed $800 with installation for a window, portable air conditioner, or fan and not to exceed $1,000 for an existing wall sleeve unit, will be provided per applicant household. No additional HEAP cash benefits are available.
Your household eligibility requirements include filing an application with your local department of social services, providing all necessary documentation, and the household must reside in an eligible living situation.
A tune-up of your central air conditioner unit can improve its efficiency and increase its life span. Without regular cleaning and maintenance, an air conditioner can lose up to 5% of its original efficiency for each year of operation.
Algoma Utilities offers cash incentives to encourage regular inspection and maintenance of central air conditioners. If you are a homeowner or business owner with a central air conditioner, you may be eligible for up to $35 toward a professional service inspection and tune-up.
Universal x86 Tuning Utility is a powerful tool designed to assist users in optimising the performance and settings of their x86 laptops and computers. Its primary objective is to provide users with the ability to customise and fine-tune their device settings according to their preferences and needs.
One of the main features of the utility is the fine-grained control it offers over the device's processor and GPU(s). Users can access a wide range of settings, allowing them to adjust clock speeds, power limits, voltages, and other performance-related parameters.
Universal x86 Tuning Utility represents a comprehensive and user-friendly tool for fine-tuning x86 laptops and computers. Its lightweight nature and extensive customisation options make it an appealing choice for those seeking to maximise the performance and efficiency of their systems, especially if they are equipped with AMD Ryzen or Intel 4th gen and newer processors.
Universal x86 Tuning Utility offers a remarkable advantage that enables users to harness a significant boost in performance without the need to invest in a new laptop, effectively enhancing the longevity and efficiency of their current Zen-based or Intel processor.
By unlocking the hidden potential of your processor through this intuitive and user-friendly utility, you can maximise your system's capabilities, ensuring it remains up to par with the ever-evolving demands of modern computing.
Universal x86 Tuning Utility also includes premade presets for Zen based processors. Premade presets offer convenience and efficiency by providing ready-to-use settings for specific needs, saving time and effort while ensuring consistent and optimised results. They serve as excellent starting points for customisation and encourage experimentation, enhancing the overall user experience across various domains.
In addition, Universal x86 Tuning Utility includes an adaptive mode. This mode allows for an adaptive TDP algorithm that aims to find the best possible power limits for your processor. This is done by monitoring the temperatures of the processor and then using this data to balance off the power limits to find the most stable settings for performance.
The Gurobi Optimizer provides a wide variety ofparameters that allow you to controlthe operation of the optimization engines. The level of controlvaries from extremely coarse-grained (e.g., theMethod parameter, which allows you tochoose the algorithm used to solve continuous models) to veryfine-grained (e.g., theMarkowitzTol parameter, whichallows you to adjust the tolerances used during simplex basisfactorization). While these parameters provide a tremendous amount ofuser control, the immense space of possible options can present asignificant challenge when you are searching for parameter settingsthat improve performance on a particular model. The purpose of theGurobi tuning tool is to automate this search.The Gurobi tuning tool performs multiple solves on your model,choosing different parameter settings for each solve, in a search forsettings that improve runtime. The longer you let it run, the morelikely it is to find a significant improvement. If you are using aGurobi Compute Server, you can harness the power of multiple machinesto perform distributed parallel tuning in order to speed up the searchfor effective parameter settings.The tuning tool can be invoked through two different interfaces. Youcan either use the grbtune command-line tool, or you can invoke it from one ofour programming language APIs. Bothapproaches share the same underlying tuning algorithm. Thecommand-line tool offers more tuning features. For example, it allowsyou to provide a list of models to tune, or specify a list of basesettings to try(TuneBaseSettings).A number of tuning-related parameters allow you to control theoperation of the tuning tool. The most important is probablyTuneTimeLimit, which controlsthe amount of time spent searching for an improving parameter set.Other parameters includeTuneTrials (which attempts tolimit the impact of randomness on the result),TuneCriterion (which specifiesthe tuning criterion),TuneResults (which controls thenumber of results that are returned), andTuneOutput (which controls theamount of output produced by the tool).Before we discuss the actual operation of the tuning tool, let usfirst provide a few caveats about the results. While parametersettings can have a big performance effect for many models, theyaren't going to solve every performance issue. One reason is simplythat there are many models for which even the best possible choice ofparameter settings won't produce an acceptable result. Some modelsare simply too large and/or difficult to solve, while others may havenumerical issues that can't be fixed with parameter changes.Another limitation of automated tuning is that performance on a modelcan experience significant variations due to random effects(particularly for MIP models). This is the nature of search. TheGurobi algorithms often have to choose from among multiple, equallyappealing alternatives. Seemingly innocuous changes to the model(such as changing the order of the constraint or variables), or subtlechanges to the algorithm (such as modifying the random number seed)can lead to different choices. Often times, breaking a single tie ina different way can lead to an entirely different search. We've seencases where subtle changes in the search produce 100X performanceswings. While the tuning tool tries to limit the impact of theseeffects, the final result will typically still be heavily influencedby such issues.The bottom line is that automated performance tuning is meant to givesuggestions for parameters that could produce consistent, reliableimprovements on your models. It is not meant to be a replacement forefficient modeling or careful performance testing.
