| | Threaded code - Wikipedia, the free encyclopedia |
 | | Huffman threaded code is one of the most compact representations known for a computer program. | | | In computer science, the term threaded code refers to an implementation technique for programming languages that produces very compact code. | | | In systems with virtual memory (where memory is simulated with a mechanical disk drive), threaded code may be hundreds of times faster than a less-compact design that does not fit in the available physical memory, because disk drives tend to be roughly a thousand times slower than random-access memory (RAM). |

| | Together with GNU gcc's computed goto statement it is possible to write a threaded code interpreter without resorting to machine language. | | | Cint [18], a C language interpreter, shuns threaded code techniques, claiming they are machine dependent. | | | To avoid the machine dependency problem, Ertl [31] uses a feature of GNU gcc [90] to generate a threaded code interpreter from a C language source. |

| | Using Visual J++ -- Chapter 16 |
| | Threaded programming is a new concept for most programmers, even the programmers who have programmed for years in other languages. | | | The threads of a program are execution paths that make your users think a program can do multiple tasks at the same time. | | | Due to the nature of threading and depending on your program, you could attempt to stop a thread that is not currently running (which triggers the pre-defined exception named IllegalThreadStateException). |

| | N-Body Particle Simulation - Naive Threaded Code |
| | When a thread is waiting on memory it can be swapped out for another process that’s memory request is ready in the cache. | | | The threaded version is limited by how fast the calculations can be performed on the CPU and thus how many CPUs can be used simultaneously. | | | This leads to the conclusion that the load is relatively balanced (and therefore threads finish computation at about the same time) when varying the number of fish. |

| | Because the thread object is exposed publically, it is possible to try out the methods by creating an instance of the thread object in a design object. | | | However, to make the threading code work correctly this object must be accessible to the CoCreateInstance call, which requires that the object is entered in the registry and is therefore public. | | | As you can see, this is not the usual way to code with objects in VB! |

| | Accessing Nanosecond Timers While Performance Tuning on Windows Servers |
| | When the code is executed the first time, it's likely to need to be brought into cache as will be the data it works on. | | | This differs from single-threaded code (where performance benefits can generally be predicted accurately by reducing instruction counts and known high-latency activities), because thread scheduling is inherently non-deterministic on Windows platforms. | | | These are caused by having the thread you're timing swapped out by the operating system. |

| | Some costs accrue from its approach: certain string operations are more expensive than in other designs because application code or a library routine must occasionally search for the end of a string, because few built-in operations are available, and because the burden of storage management for strings falls more heavily on the user. | | | The most ambitious enterprise I undertook was a genuine cross-compiler that translated B to GE-635 machine instructions, not threaded code. | | | The language changes during this period, especially around 1977, were largely focused on considerations of portability and type safety, in an effort to cope with the problems we foresaw and observed in moving a considerable body of code to the new Interdata platform. |
