The above is basic example of a namespaces. In this example, we use the std namespace, which is known as the standard namespace. In other words, as soon as you write using a namespace std, you have the ability to work with: ostream or istream. Those two classes are child classes o...
This example demonstrates how to useconcurrency::parallel_forto compute the product of two matrices. Example: Compute the product of two matrices The following example shows thematrix_multiplyfunction, which computes the product of two square matrices. ...
you had to saystd::pair<int, int> p(11, 22);, despite the fact that the compiler already knows that the types of11and22areint. The workaround for this limitation was to use function template argument deduction:std::make_pair(11, 22)returnsstd::pair<int, int...
The following example demonstrates the data marshaling required to access an ANSI string in a managed function that is called by an unmanaged function. The managed function, on receiving the native string, can either use it directly or convert it to a managed string using thePtrToStringAnsimethod,...
The following example code computes adding two vectors that use pointers to invoke a host function inside a kernel. #include <CL/sycl.hpp> #include <iostream> #include "header.h" #define numElements 10 using namespace std; int main(void){ size_t size = numElements * sizeof(float); cl...
To manage a scheduler instance in your application Create aconcurrency::SchedulerPolicyobject that contains the policy values for the scheduler to use. Call theconcurrency::CurrentScheduler::Createmethod or theconcurrency::Scheduler::Createmethod to create a scheduler instance. ...
To avoid this expansion, you can use the noalias() function. a.noalias() += b*c; This will avoid the dynamic memory allocation, because you tell Eigen explicitely not to use the temporary matrix. When noalias() doesn't cut it But be careful with noalias()! There is another line where...
Whenever possible, use the make_shared function to create a shared_ptr when the memory resource is created for the first time. make_shared is exception-safe. It uses the same call to allocate the memory for the control block and the resource, which reduces the construction overhead. If you...
How to Use Output Stream inside the Kernel The following is an example program to demonstrate how to useoutput streaminside a kernel: #include<CL/sycl.hpp>usingnamespacesycl;intmain(){intN=8;queueq(default_selector{});q.submit([&](handler&h){sycl::streamout(1024,256,h);h.parallel_fo...
