<h2 class="first-section-title"><a name="25"></a><a name="introlev1sec3"></a>Audience</h2><p class="first-para">This book is directed toward professional developers and students who are interested in discovering how memory is managed on production systems. Specifically, engineers working on PC or embedded operating systems may want to refresh their memory or take a look at alternative approaches. If this is the case, then this book will serve as a repository of algorithms and software components that you can apply to your day-to-day issues.</p>
<p class="para">Professionals who design and construct development tools will also find this book useful. In general, development tools fall into the class of online transaction processing (OLTP) programs. When it comes to OLTP apps, pure speed is the name of the game. As such, programming language tools, like compilers, often make use of suballocators to speed up the performance of the code that manipulates their symbol table.</p>
<p class="para">With regard to compiling large software programs consisting of millions of lines of code, this type of suballocator-based optimization can mean the difference between waiting for a few minutes and waiting for a few hours. Anyone who mucks around with suballocators will find this book indispensable.</p>
<p class="para">Software engineers who work with virtual machines will also be interested in the topics that I cover. The Java virtual machine is famous for its garbage collection facilities. In this book I explore several automatic memory management techniques and also provide a couple of concrete garbage collection implementations in C++.</p>
<p class="last-para">Finally, this book also targets the curious. There is absolutely nothing wrong with being curious. In fact, I would encourage it. You may be an application developer who has used memory management facilities countless times in the past without taking the time to <a name="26"></a><a name="IDX-xix"></a>determine how they really work. You may also have nurtured an interest that you have had to repress due to deadlines and other priorities. This book will offer such engineers an opportunity to indulge their desire to see what is going on under the hood.</p>
