Hi,
>>This uses VS2019 creates vector-add-buffers.exe and vector-add-usm.exe, but not vector-add.exe. There is one warning but no errors.
Does it run in the scenario or are you facing the same issue again?
Could you please try to build/run the simple vector add code below:
#include <CL/sycl.hpp>
#include <iostream>
#include <vector>
using namespace sycl;
#define size 1024
int main() {
std::vector<int> A(size, size), B(size, size), C(size, 0);
{ //SYCL scope begins
queue q;
range<1> R(size);
buffer<int,1> buffA(A.data(), R);
buffer<int,1> buffB(B.data(), R);
buffer<int,1> buffC(C.data(), R);
std::cout<< "Running on: "<<q.get_device().get_info<info::device::name>()<<"\n";
q.submit([&](handler &cgh) {
auto acc_buffA = buffA.get_access<access::mode::read>(cgh);
auto acc_buffB = buffB.get_access<access::mode::read>(cgh);
auto acc_buffC = buffC.get_access<access::mode::write>(cgh);
cgh.parallel_for(R, [=](id<1> i) {
acc_buffC[i] = acc_buffA[i] + acc_buffB[i];
}
);
});
} //SYCL scope ends
std::vector<int> vecValidate(size, 2*size);
(C==vecValidate) ? std::cout << "Success\n" : std::cout<<"Failure\n";
return 0;
}
Steps to build and run the code:
- Open the "Intel oneAPI command prompt for Visual Studio-19" in order to automatically source the oneAPI environment.
- If you do not find the oneAPI command prompt, to manually source the oneAPi environment, open the usual Microsoft command prompt and execute the below command (From oneAPI_root installation directory):
cd "C:\Program Files (x86)\Intel\oneAPI" && setvars.bat
dpcpp simplevecadd.cpp -o sva.exe && sva.exe
Let us know if you face any issues.
Regards,
Rahul
