I would like to know if scalable_malloc makes any guarantees about zero-initialized memory (for example: always zero-initialized up to requests for X bytes), whether or not this fact can be queried with the API (as in up to how many bytes this guarantee covers) and if it's going to stay like this in the future.
I need to guarantee zero-initialized memory for a project I'm working on, and it's a waste of precious CPU cycles to zero-initialize something if it's already zero-initialized.
Thanks in advance.
The solution files in the package are for Microsoft Visual Studio* 2013. Later versions of Microsoft Visual Studio can convert them.
To run a solution file in <examples_dir>\*\*\msvs\ directory:
Start Microsoft Visual Studio*.
Open a solution file in the msvs directory.
You can successfully parallelize many applications using only the constructs in the Parallelizing Simple Loops section. However, some situations call for other parallel patterns. This section describes the support for some of these alternate patterns.
In a dependence graph, the nodes invoke body objects to perform computations and the edges create a partial ordering of these computations. At runtime, the library spawns and schedules tasks to execute the body objects when it is legal to do so according to the specified partial ordering. The following figure shows an example of an application that could be expressed using a dependence graph.
You may want to control the number of messages allowed to enter parts of your graph, or control the maximum number of tasks in the work pool. There are several mechanisms available for limiting resource consumption in a flow graph.
The discussion so far was simplified by assuming non-nested parallelism and skipping details of task_group_context. This topic explains both.
