gettimeofday() requires a pointer to a struct timeval to fill with time data. So, for example, you'd do something like this: #include <sys/time.h> #include <stdio.h> int main() { struct timeval tv; gettimeofday(&tv, NULL); // timezone should be NULL printf("%d...
gettimeofday 函数来得到精确时间。它的精度可以达到微妙,是C标准库的函数。最后的 free 函数把申请的3段内存释放掉。 编译: g++ -O3 main_cpu.cpp -o VectorSumCPU 我们再看一下 CUDA 执行向量相加的代码: #include <iostream> #include <cstdlib> #include <sys/time.h> #include <cuda_runtime.h> ...
Calculate Elapsed Time in a Code Block in C Using the gettimeofday Function In C programming, the gettimeofday function is a powerful tool for obtaining accurate time information. The gettimeofday function is commonly used in Unix-like operating systems to retrieve the current time with microsecond ...
