  2. Slab allocation - Wikipedia

    en.wikipedia.org/wiki/Slab_allocation

    The three allocators provides a kind of front-end to the zoned buddy allocator for those sections of the kernel that require more flexible memory allocation than the standard 4 KB page size). NetBSD (introduced in 4.0) Solaris (introduced in 2.4) The Perl 5 compiler uses a slab allocator for internal memory management [10] [11]

  3. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    In 1988, researchers began investigating how to use regions for safe memory allocation by introducing the concept of region inference, where the creation and deallocation of regions, as well as the assignment of individual static allocation expressions to particular regions, is inserted by the compiler at compile-time. The compiler is able to ...

  4. Instruction selection - Wikipedia

    en.wikipedia.org/wiki/Instruction_selection

    In computer science, instruction selection is the stage of a compiler backend that transforms its middle-level intermediate representation (IR) into a low-level IR. In a typical compiler, instruction selection precedes both instruction scheduling and register allocation; hence its output IR has an infinite set of pseudo-registers (often known as temporaries) and may still be – and typically ...

  5. Stack-based memory allocation - Wikipedia

    en.wikipedia.org/wiki/Stack-based_memory_allocation

    Many Unix-like systems as well as Microsoft Windows implement a function called alloca for dynamically allocating stack memory in a way similar to the heap-based malloc.A compiler typically translates it to inlined instructions manipulating the stack pointer, similar to how variable-length arrays are handled. [4]

  6. Profile-guided optimization - Wikipedia

    en.wikipedia.org/wiki/Profile-guided_optimization

    The HotSpot Java virtual machine (JVM) uses profile-guided optimization to dynamically generate native code. As a consequence, a software binary is optimized for the actual load it is receiving. If the load changes, adaptive optimization can dynamically recompile the running software to optimize it for the new load.

  7. Memory pool - Wikipedia

    en.wikipedia.org/wiki/Memory_pool

    Fixed-size block memory pools do not need to store allocation metadata for each allocation, describing characteristics like the size of the allocated block. Particularly for small allocations, this provides substantial space savings. Allows deterministic behavior on real-time systems avoiding the out of memory errors. Drawbacks

  8. Manual memory management - Wikipedia

    en.wikipedia.org/wiki/Manual_memory_management

    In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.

  9. Java memory model - Wikipedia

    en.wikipedia.org/wiki/Java_memory_model

    To be able to draw conclusions about a program's behavior, Java's designers decided they had to clearly define possible behaviors of all Java programs. On modern platforms, code is frequently not executed in the order it was written. It is reordered by the compiler, the processor and the memory subsystem to achieve maximum performance.
