这些函数以__作为前缀,例如__sinf(x)。编译器有一个选项-use_fast_math,指定该选项后将在编译时强制下表中的每个函数编译为其对应的内部函数。 内部函数除了会降低函数的计算结果的精度外,还可能在一些特殊情况下与标准函数存在差异。所以推荐通过调用内联函数来选择性地替换标准数学函数,具体是否替换需要用户根据...
CUDA Math device functions are no-throw for well-formed CUDA programs.Note that many floating-point and integer functions names are overloaded for different argument types. For example, the log() function has the following prototypes: double log(double x); float log(float x); float logf(...

(2)CUDA编译器实际上是一个C++编译器,在math_functions.h之类的头文件里面,有C++风格的重载。例如sqrt()函数,有double sqrt(double)的版本的,也有float sqrt(float)的版本的。如果用户不小心,在式子里面给出了double的中间结果作为参数,同时函数结尾没有显式的写出f()结尾,那么因为重载的同名函数存在,将实际上使...

mathKernel2不报告分支分化的唯一原因是它的分支粒度是线程束大小的倍数。 ·当一个分化的线程采取不同的代码路径时,会产生线程束分化 ·不同的if-then-else分支会连续执行 ·尝试调整分支粒度以适应线程束大小的倍数,避免线程束分化 ·不同的分化可以执行不同的代码且无须以牺牲性能为代价 ...
