| | Dynamic memory allocation - Wikipedia, the free encyclopedia |
 | | In heap-based memory allocation, memory is allocated from a large pool of unused memory area called the heap (this has nothing to do with the heap data structure; this is an overloaded term). | | | In computer science, dynamic memory allocation is the allocation of memory storage for use in a computer program during the runtime of that program. | | | A dynamically allocated object remains allocated until it is deallocated explicitly, either by the programmer or by a garbage collector; this is notably different from automatic and static memory allocation. |

| | Stack-based memory allocation - Wikipedia, the free encyclopedia |
| | Stacks in computing architectures are typically low-level programing constructs involving memory following a Last-In-First-Out method. | | | A CPU stack is usually maintained by a special set of instructions that the microprocessor has available in the CPU instruction set. | | | A stack is a convenient way of passing parameters between routines and storage of local variables. |

| | Memory allocation and deallocation is much faster, because it is all done a pool at a time. | | | Memory as a Programming Concept in C and C++ by Frantisek Franek discusses techniques and tools for developing effective memory use and gives the role of memory-related errors the prominence it deserves in computer programming. | | | Memory management is one of the most fundamental areas of computer programming. |

| | Memory Allocation |
| | To simplify this case, we define a simple, stack-based system that remembers the allocated memory and provides a simple way to ensure that all allocations are freed before an error return. | | | These routines should be used only for the allocation of memory within MPI objects, such as copies of index arrays needed for MPI indexed datatypes and info value strings. | | | Memory allocation follows the usual rules for a separate subpackage: there are initialization routines and a registered routine to be called in MPI_Finalize. |

| | Safe Memory Utilization |
| | While each task must have its own stack, it may or may not have its own heap, regardless of whether the heap is based on the static allocation scheme, pools, or a general purpose allocation scheme. | | | A library may allow the application code to create an object, or allocate memory in some way, but the library may not be able to free that item because the library does not know when the application has finished with it. | | | If all memory is allocated statically, then exactly how each byte of RAM will be used during the running of the program can be established at compile time. |

| | CommsDesign - Solving AMR Speech Codec Porting Challenges |
| | A simple example of how a program can be converted from a standard stack-based memory allocation to one that uses memory allocation and a scratch structure is given in Code Listing 1 and Listing 2. | | | Customizing the memory allocation methods and location of key buffers, along with rewriting specific functions in assembly language and intelligently using C compiler features leads to delivering a highly optimized and easily integrated algorithm in the shortest period of time. | | | One method of minimizing the possibility of memory leaks is to create a scratch memory structure by analyzing how memory is allocated in each function and then placing those allocations in a C structure. |

| | 3.4.1.1 Shared-Memory Management |
| | Hence, stack-based local memory allocation makes for more efficient memory usage since memory is allocated to each routine only when required. | | | A stack-based memory management scheme was crucial in designing a shared-memory multitasked version of CCM3.9. | | | Thus, use of the stack is the only reasonable way to ensure that multitasked routines are "reentrant," i.e., they may be entered by more than one processor at once without violating previously defined data space. |

| | Memory Allocation Optimization - 3DSoftware.com |
| | Graphics programs that require frequent memory allocation and deallocation can be optimized to handle some of the memory allocation functionality themselves. | | | The shared memory block is called a “file-mapping object” and is passed as the hSection parameter (the OS programmers thought of it as a “section” of memory). | | | Another efficiency would be to create a separate header for each memory block, instead of using the first node header in a block as that block's header. |

| | Using only stack allocation, without heap allocation, is somewhat restrictive, as only objects whose size is known at compile-time can be returned from a procedure. | | | Stack allocation means run-time allocation and deallocation of storage in last-in/first-out order. | | | Typically, stack allocation is performed on top of the main stack, but one can have a separate data stack for this purpose as well, as in Forth, or even multiple ones, as in the PostScript® language. |

| | Memory Allocation |
| | In general, when using pointers you always have to consider memory allocation, at least to make sure that the compiler is doing it for you. | | | C compilers only allocate memory for objects explicitly mentioned in the source code (in the case of "strings," this includes character arrays and string literals). | | | Nevertheless, some personal computers are said not to reliably recover memory, and all that can be inferred from the ANSI/ISO C Standard is that it is a "quality of implementation issue." |
