  2. Stack trace - Wikipedia

    en.wikipedia.org/wiki/Stack_trace

    In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...

  3. strace - Wikipedia

    en.wikipedia.org/wiki/Strace

    Specifying a filter of syscall names that should be traced (via the -e trace= option): by name, like clone,fork,vfork; using one of the predefined groups, like %ipc or %file; or (since strace 4.17) using regular expression syntax, like -e trace=/clock_.*. Specifying a list of paths to be traced (-P /etc/ld.so.cache, for example).

  4. Clock (model checking) - Wikipedia

    en.wikipedia.org/wiki/Clock_(model_checking)

    In model checking, a subfield of computer science, a clock is a mathematical object used to model time. More precisely, a clock measures how much time passed since a particular event occurs, in this sense, a clock is more precisely an abstraction of a stopwatch. In a model of some particular program, the value of the clock may either be the ...

    en.wikipedia.org/wiki/X86_instruction_listings

    Using a data size of 16 bits will cause only the bottom 16 bits of the 32-bit general-purpose registers to be modified – the top 16 bits are left unchanged.) The default OperandSize and AddressSize to use for each instruction is given by the D bit of the segment descriptor of the current code segment - D=0 makes both 16-bit, D=1 makes both 32 ...

  6. TimeClock Plus - Wikipedia

    en.wikipedia.org/wiki/TimeClock_Plus

    The core Time Clock mounts to a wall and is configurable with multiple input methods including a touch screen [3] and touch-less options. The MobileClock app and WebClock application enable employees to clock in and out while data is recorded in a Microsoft SQL database. TimeClock Manager is a web application for administrators to review hours ...

  7. Einstein synchronisation - Wikipedia

    en.wikipedia.org/wiki/Einstein_synchronisation

    Einstein synchronisation (or Poincaré–Einstein synchronisation) is a convention for synchronising clocks at different places by means of signal exchanges. This synchronisation method was used by telegraphers in the middle 19th century, [citation needed] but was popularized by Henri Poincaré and Albert Einstein, who applied it to light signals and recognized its fundamental role in ...

  8. Vector clock - Wikipedia

    en.wikipedia.org/wiki/Vector_clock

    A vector clock of a system of N processes is an array/vector of N logical clocks, one clock per process; a local "largest possible values" copy of the global clock-array is kept in each process. Denote V C i {\displaystyle VC_{i}} as the vector clock maintained by process i {\displaystyle i} , the clock updates proceed as follows: [ 1 ]

  9. Frequency-resolved optical gating - Wikipedia

    en.wikipedia.org/wiki/Frequency-resolved_optical...

    For example, say that the measured trace consists of 128 points in the delay direction and 128 points in the frequency direction. There are 128×128 total points in the trace. Using these points, an electric field is retrieved that has 2×128 points (128 for magnitude and another 128 for the phase).
