in the early- and mid-1970s for the first time encapsulated the principles and elements of Forth as it is used today. For this reason, we shall summarize these briefly. 2.4.1 Design principles Much as algebra was the “metaphor” for FORTRAN, Forth was conceived on the model of English ...
展平模型 Flat memory model,内存对于程序就是一个完整连续空间,即线性地址空间,按字节寻址,代码、数据、调用栈全都在这个空间里。在这个线性连续空间的任体一个字节的地址都叫线性地址,如果不是 64-bit 架构,最大可寻址 2^32 共 4GB。 分段模型,分段的内存对程序来说就是独立的地址空间,代码、数据、堆栈通常...

1 Data Abstraction C++ directly supports the use of programmer-defined data types that function much like the predefined data types already in the language. Such abstract data types can be defined to model the problem being solved. Object-Oriented Features The class, the fundamental unit of data...
Whenever concurrent programs share memory, as OpenMP programs do, the programming model inevitably becomes very subtle. 5.1.1 OpenMP syntax OpenMP syntax is beguilingly simple. leibniz.hh leibniz.cpp ompfor.cpp parallel.cpp section.cpp 5.1.2 Shared variables and OpenMP's memory model Implicit ...
