使用default子句,程序员可以更改这种默认行为。default(none)指定在并行区域内,除非明确指定为shared或private,否则所有变量都是未定义的。这要求程序员显式地指定每个变量的作用域;default(shared),显式地指定了除非明确指定为private,否则所有变量在并行区域内都是共享的,实际上恢复了OpenMP的默认行为。firstprivate #incl...
default(shared | none) Remarks shared, which is in effect if the default clause is not specified, means that any variable in a parallel region will be treated as if it were specified with the shared (OpenMP) clause. none means that any variables used in a parallel region that are not ...
registerized inside the loops. And in this case you code was lucky. Do not assume that because this test ran without issue that the code itself was not error free. It just happened to be error free (but not by design). You should use the OpenMP clause default(none)...
this is a very small comment about OpenMP "default(none)" andprocedure pointers. In fact, ifort compiles the attached code, eventhough the variable pf is not specified to be either private orshared, which seems incorrect to me. Regards, Marco Restelliifort -VIntel Fortran Intel 64 Compil...
Tells the compiler that all ALLOCATE statements should be treated as though there were an explicit OpenMP ALLOCATE directive that preceded them. This feature is only available for ifx.

对于Fortran,也接受 DEFAULT(__AUTO)。并行或任务构造中的 default(__auto) 子句可指示编译器自动确定构造中引用的所有未在任何数据作用域子句中显式确定作用域的变量的作用域。 default(__auto) 子句可以出现在 PARALLEL、PARALLEL DO/for、PARALLEL SECTIONS、Fortran 95 PARALLEL WORKSHARE 或TASK 指令中。
