Unable to build the Vector Add sample on windows 10

Hi there!

I have just started learning DPC++ and I was going through the tutorials. I tried running the Vector Add example provided by intel oneAPI, but it shows the following errors:

Build started...

Hi Nikhil,

Thanks for reaching out to us.

Please try selecting the Windows SDK for any newer versions. You can select it from the below path.

Project Property -> Configuration Properties -> General -> Windows SDK Version.

Also, try running the same sample (vector_add) using command line and let us know if you observed any errors.

It seems that this problem is related to your Visual Studio Environment.

Warm Regards,

Abhishek.

Okay I will try it and get back to you!

Changing the windows SDK thing really worked for me!! Thanks you for the help. I wanted to know if there is a way by which I can use it one Nvidia GPU?

Thanks again for the help!!

Though I am able to solve the problem, I am still seeing these errors which aren't affecting the compilation process. Image attached.

Hi Nikhil,

Thanks for the confirmation, glad to know that it solved your issue.

The error logs which you are getting on the VS is because buffer & accessor are templated functions and I think you have not specified any template arguments for example like buffer<float, 2>. That's the reason you can only see the error logs on VS but at a time of compiling it's compiling with no errors. You may try giving template arguments to buffer to remove those error logs.

Warm Regards,

Abhishek

Could you also tell if it is possible to work with nvidia GPUs using DPC++ ?

Re:Unable to build the Vector Add sample on windows 10

AbhishekD_Intel — Wed, 23 Dec 2020 06:49:39 GMT

Hi,

It is possible to use DPC++ for NVIDIA GPUs. Please follow the below link for more details.

Let us know if your issue has been resolved. So that we can close this thread. You are always welcome to post a new thread if you have any other issues.

I am trying to run a simple code to test the performance of parallel processing. The code is presented below:

#include <CL/sycl.hpp>
#include <vector>
#include <iostream>
#include <numeric>
#include <ctime>
using namespace sycl;

int main() {

std::vector<int> vec(10000);
std::iota(std::begin(vec), std::end(vec), 0);
std::vector<int> vec_serial(10000);
std::vector<int> vec_parallel(10000);
clock_t begin_serial = clock();
for (int i = 0; i < vec.size(); i++) {
vec_serial[i] = vec[i] + 2;
}
clock_t end_serial = clock();
double time_serial = double(end_serial - begin_serial);

queue Q{ host_selector() };
clock_t begin_parallel ;
clock_t end_parallel;
{

buffer b1{ vec };
buffer b2{ vec_parallel };
begin_parallel = clock();
Q.submit([&](handler& h) {
accessor a1{ b1 , h };
accessor a2{ b2 , h };
h.parallel_for(10000,[=](id <1>i) {

a2[i] = a1[i] + 2;

});

}).wait();
end_parallel = clock();

}
double time_parallel = double(end_parallel - begin_parallel);
std::cout << "The time taken for serial operation is " << time_serial;
std::cout << "\nThe time taken for parallel operation is" << time_parallel;
return 0;
}

The code measures the time taken to produce the results. I am compiling it in Visual Studio environment and building it there. However the time taken for computation in the serial case seems to be way lesser than the parallel mode. Am I missing something??

Hi Nikhil,

Please try running a more complex workload. You will find the time difference in more compute-intensive workloads. Though there will be some overhead to create a queue, still you will find a good difference if you use a more compute-intensive workload.

Hope these details will help you to compare the time differences.

As your issue is resolved, please give us confirmation if we can close this thread. You are always welcome to post a new thread if you have any other issues.

Hi there!

This issue is resolved now. I tried using VTune to check the code and it seems that this parallel version of this code does not performs well. I will try using heavy application to see the difference.

Thank you!
