• ORG.SHIRAKUMO.MACHINE-STATE

  No documentation provided.

  • EXTERNAL CONDITION

    QUERY-FAILED

    Source

    Error signalled if a query should fail for some reason.
    
    This condition is *NOT* signalled if the function is simply
    unsupported. It is however signalled if an OS call failed for some
    reason such as lack of access permissions.

  • EXTERNAL FUNCTION

    GC-ROOM

    Source

    Returns the GC's memory usage statistics.
    
    This does not include foreign memory usage.
    
    Returns two values:
      The number of free bytes
      The total number of bytes available
    
    If the function is unsupported a constant 0 is returned for both
    values.

    See PROCESS-ROOM
    See GPU-ROOM

  • EXTERNAL FUNCTION

    GC-TIME

    Source

    Returns the amount of processing time spent in the GC.
    
    If the function is unsupported a constant 0.0d0 is returned.
    
    See PROCESS-TIME
    See GC-TIME
    See THREAD-TIME

  • EXTERNAL FUNCTION

    GPU-ROOM

    Source

    Returns the GPU's memory usage statistics.
    
    Returns two values:
      The number of free bytes
      The total number of bytes available
    
    If the function is unsupported a constant 0 is returned for both
    values.
    
    You may want to load the machine-state/opengl library to make this
    function useful. In that case, it will only work if an OpenGL context
    is current to this thread.

  • EXTERNAL FUNCTION

    GPU-TIME

    Source

    Returns the amount of processing time spent on the GPU by this process.
    
    If the function is unsupported a constant 0.0d0 is returned.
    
    You may want to load the machine-state/opengl library to make this
    function useful. In that case, it will only work if an OpenGL context
    is current to this thread.

  • EXTERNAL FUNCTION

    MACHINE-CORES

    Source

    Returns the number of cores available on the machine.

  • EXTERNAL FUNCTION

    MACHINE-ROOM

    Source

    Returns the machine's primary memory usage statistics.
    
    Returns two values:
      The number of physical bytes occupied
      The total number of physical bytes available
    
    If the function is unsupported a constant 0 is returned for both
    values.
    
    See GC-ROOM
    See GPU-ROOM
    See PROCESS-ROOM

  • EXTERNAL FUNCTION

    PROCESS-IO-BYTES

    Source

    Returns the number of bytes of IO performed by the process.
    
    IO in this context refers to any activity to external devices such as
    drives, networking, etc.
    
    If the function is unsupported a constant 0 is returned.

  • EXTERNAL FUNCTION

    PROCESS-ROOM

    Source

    Returns the process' memory usage statistics.
    
    This includes foreign memory usage.
    
    Returns the number of bytes occupied.
    
    If the function is unsupported a constant 0 is returned.
    
    See GC-ROOM
    See MACHINE-ROOM

  • EXTERNAL FUNCTION

    PROCESS-TIME

    Source

    Returns the amount of processing time spent by this process in seconds.
    
    This does not include time spent in the kernel.
    
    If the function is unsupported a constant 0.0d0 is returned.
    
    See THREAD-TIME
    See GC-TIME
    See GPU-TIME

  • EXTERNAL FUNCTION

    THREAD-CORE-MASK

    • THREAD

    Source

    Accessor to the CPU core affinity mask of the thread.
    
    The mask is a bitfield where each set bit in the integer designates a
    core that the thread may be executed on. For compatibility reasons
    only integers up to 64 bits are supported.
    
    Thread may be T for the current thread, or a BT:THREAD.
    
    If the function is unsupported a constant of all 1s is returned.
    
    When setting this place, the *actual* affinity mask of the thread is
    returned, which may differ from the one you tried to set.

  • EXTERNAL FUNCTION

    (SETF THREAD-CORE-MASK)

    • MASK
    • THREAD

    Source

  • EXTERNAL FUNCTION

    THREAD-TIME

    • THREAD

    Source

    Returns the amount of processing time spent by this thread in seconds.
    
    This does not include time spent in the kernel.
    
    Thread may be T for the current thread, or a BT:THREAD.
    
    If the function is unsupported a constant 0.0d0 is returned.
