  2. Go (programming language) - Wikipedia

    en.wikipedia.org/wiki/Go_(programming_language)

    For a pair of types K, V, the type map[K]V is the type mapping type-K keys to type-V values, though Go Programming Language specification does not give any performance guarantees or implementation requirements for map types. Hash tables are built into the language, with special syntax and built-in functions.

  3. Go! (programming language) - Wikipedia

    en.wikipedia.org/wiki/Go!_(programming_language)

    [1] [4] The issue received attention among technology news websites, with some of them characterizing Go! as "obscure". [5] The issue thread opened on the subject was closed by a Google developer on 12 October 2010 with the custom status "Unfortunate" and with the following comment: "there are many computing products and services named Go.

  4. Cache placement policies - Wikipedia

    en.wikipedia.org/wiki/Cache_placement_policies

    Cache placement policies are policies that determine where a particular memory block can be placed when it goes into a CPU cache.A block of memory cannot necessarily be placed at an arbitrary location in the cache; it may be restricted to a particular cache line or a set of cache lines [1] by the cache's placement policy.

  5. Memory map - Wikipedia

    en.wikipedia.org/wiki/Memory_map

    In computer science, a memory map is a structure of data (which usually resides in memory itself) that indicates how memory is laid out. The term "memory map" has different meanings in different contexts. It is the fastest and most flexible cache organization that uses an associative memory. The associative memory stores both the address and ...

  6. Memory ordering - Wikipedia

    en.wikipedia.org/wiki/Memory_ordering

    [1] [4] Conversely, the memory order is called weak or relaxed when one thread cannot predict the order of operations arising from another thread. [1] [4] Many naïvely written parallel algorithms fail when compiled or executed with a weak memory order. [5] [6] The problem is most often solved by inserting memory barrier instructions into the ...

  7. Race condition - Wikipedia

    en.wikipedia.org/wiki/Race_condition

    "Two memory operations, x and y, in a sequentially consistent execution form a race 〈x,y〉, iff x and y conflict, and they are not ordered by the hb1 relation of the execution. The race 〈x,y〉, is a data race iff at least one of x or y is a data operation. Here we have two memory operations accessing the same location, one of which is a ...

  8. Memory access pattern - Wikipedia

    en.wikipedia.org/wiki/Memory_access_pattern

    In computing, a memory access pattern or IO access pattern is the pattern with which a system or program reads and writes memory on secondary storage.These patterns differ in the level of locality of reference and drastically affect cache performance, [1] and also have implications for the approach to parallelism [2] [3] and distribution of workload in shared memory systems. [4]

  9. Region-based memory management - Wikipedia

    en.wikipedia.org/wiki/Region-based_memory_management

    e 1 at ρ: Compute the result of the expression e 1 and store it in region ρ; let region ρ in e 2 end: Create a region and bind it to ρ; evaluate e 2; then deallocate the region. Due to this syntactic structure, regions are nested, meaning that if r 2 is created after r 1, it must also be deallocated before r 1; the result is a stack of ...
