Profiling windows

The engine is taking it straight to the seat, and you know you have to go above the fire and quickly. Seconds may matter. Where are the people likely to be? What is about to light up? What access and egress point will give your team the greatest odds? Sometimes, windows and the conditions at them can be of tremendous service to us.

They can be as equally helpful to us on arrival as they are on the interior; windows are, too often, overlooked. So much is said about when, where, and how to take them. If you arrive to any number of private dwellings, be it standalone, row frame, or apartment, the window conditions can be of great assistance.

Windows in apartment buildings, framed or occupied multiple dwellings can be equally helpful. Generally, you can assume that windows that have not yet failed to have no great heat or fire condition behind them, barring, of course, thermo-paned windows.

In this instance, community, age of construction, or the possibility of replacements may be your indicators.

Windows with smoke filling their whole surface area—depending on color—can indicate conditions and survivability close to that location. If a window or a door is showing you moving black smoke at the upper reaches I always think the upper third , the fire is probably on that level a few rooms back from that specific window and is fairly intense.

It is hot enough that the smoke is exiting at the highest point possible. There are many indicators, but the thrust is to look at HOW current is leaving a window. The size, type, and proximity of windows tell us a great deal. Black smoke under pressure, we are all taught, is an indicator of looming flashover. But what if it is pushing out of a smaller window than normal? Smoke, similar to the water, narrowing toward the tip of the nozzle, behaves similarly.

On a summer day, if windows are open, smoke rushing out of the bottom pane is NOT the same as smoke rushing in a similar fashion from a failed window. The smoke is exiting a violent atmosphere and hanging in a humid one. It looks very similar to chugging smoke.

If the air-conditioner AC falls from the window and smoke is blasting out, this can mean the same thing. The bottom line is that smoke leaving an opening is often different than smoke leaving a failed opening. The former is likely telling you the area is not yet involved, and the latter had fire recently blowing out of it. Be cautious of what can appear to be lazy smoke from failed openings, hanging around and low, whether it is rainy or humid. These outside conditions can mask the intensity waiting within.

You will be able to take snapshots and compare how the memory usage has changed from point A to point B. But that is pretty much the extent of it.

A nice application that does memory profiling on windows is MTuner. It is an open-sourced project. I was really amazed by the power of that application. It is a simple to use application that you start and then you drag and drop the application you want to profile. It will immediately execute that application and provide you with information about its memory.

Just by looking at the first window that opens, we can see that our MemoryExample application has only allocations and no memory is ever freed. It also has a timeline view of all allocations and stack traces of when and where they happen. This project was a life saver for me and I strongly recommend it in front of all other solutions. It is non-invasive.

You just need to drag and drop your application and that is it. Consider contributing or supporting the project in any way as the tools available for windows are pretty sparse. This was a short article on memory profiling for Windows but I hope that anyone out there finds it useful. I was surprised that memory profiling is not that well explained or supported on the Windows front.

Note Enhanced security features in Windows 8 and Windows Server required significant changes in the way the Visual Studio profiler collects data on these platforms.
