How to write a scope of work statement example

But many compilers don't do this for module variables -- the variables probably retain their values -- it isn't worth the effort for the compiler to figure out whether a module remains in scope or not and probably module variables are treated as global variables -- but don't rely on that! To be safe, either use "save" or "use" the module from the main program so that it never goes out of scope. In this code fragment, "counter" will report the number of invocations of subroutine x. In contrast to the module case, with modern compilers, without the save attribute or initialization-on-a-declaration, it is normal for local variables of procedures to lose their values across invocations.

OpenMP programs accomplish parallelism exclusively through the use of threads. A thread of execution is the smallest unit of processing that can be scheduled by an operating system.

The idea of a subroutine that can be scheduled to run autonomously might help explain what a thread is. Threads exist within the resources of a single process.

Without the process, they cease to exist. However, the actual use of threads is up to the application. OpenMP is an explicit not automatic programming model, offering the programmer full control over parallelization.

Parallelization can be as simple as taking a serial program and inserting compiler directives Or as complex as inserting subroutines to set multiple levels of parallelism, locks and even nested locks. Fork - Join Model: OpenMP uses the fork-join model of parallel execution: All OpenMP programs begin as a single process: The master thread executes sequentially until the first parallel region construct is encountered.

The statements in the program that are enclosed by the parallel region construct are then executed in parallel among the various team threads. When the team threads complete the statements in the parallel region construct, they synchronize and terminate, leaving only the master thread.

The number of parallel regions and the threads that comprise them are arbitrary. Because OpenMP is a shared memory programming model, most data within a parallel region is shared by default. All threads in a parallel region can access this shared data simultaneously.

OpenMP provides a way for the programmer to explicitly specify how data is "scoped" if the default shared scoping is not desired. This topic is covered in more detail in the Data Scope Attribute Clauses section.

The API provides for the placement of parallel regions inside other parallel regions. Implementations may or may not support this feature.

The API provides for the runtime environment to dynamically alter the number of threads used to execute parallel regions. Intended to promote more efficient use of resources, if possible.

OpenMP provides a "relaxed-consistency" and "temporary" view of thread memory in their words. In other words, threads can "cache" their data and are not required to maintain exact consistency with real memory all of the time.

When it is critical that all threads view a shared variable identically, the programmer is responsible for insuring that the variable is FLUSHed by all threads as needed. More on this laterProfessional Rent & Lease Templates.

A statement of work is an important document you must write anytime you want to describe a particular job.

Vision Statement

A SOW must be clear. It should cover the scope of the job in question using a simple and easy to understand language. Scope of Work. A scope statement describes the scope of work in terms of a product, service or other result of a project.

The scope statement also specifies acceptance criteria that determine if a project result is acceptable. The SoW (statement of work or scope of work) is one of the best, and worst weapons in a project manager’s arsenal of tools.

It’s the best because a statement of work (SoW) is so often the one piece of documentation that saves you from a world of trouble. In principal when a module goes out-of-scope, the variables of that module become undefined -- unless they are declared with the SAVE attribute, or a SAVE statement is used.
