Exception unhandled at Event = submit_impl(CGF, CodeLoc);

Hi,

I have two files Library.lib and Main.cpp. Library.lib contains two files : Sample1.cpp and Sample2.cpp.

In the Library.lib file, I am trying to access a function in Sample1.cpp from Sample2.cpp within the kernel scope. But the program throws an exception at queue.hpp - > Event = submit_impl(CGF, CodeLoc); .

I appreciate your help.

Thank you.

I am unable to attach Sample1.cpp and Sample2.cpp. Below, are the contents of the two files.

Sample1.cpp

#include "Sample1.h"

Sample1::Sample1()
{

}

Sample1::~Sample1()
{

}

void Sample1::trial()
{
int c = a + b;
}

void Sample1::trial2()
{
int d = a + b;
}

Sample2.cpp

#include "Sample2.h"
#include "Sample1.h"

Sample2::Sample2()
{

}

Sample2::~Sample2()
{

}

void Sample2::trial3()
{
std::vector<int>sym_indices(4);
std::vector<int>best_syms(7);
std::vector<int>Lptemp(7);
sycl::buffer sym_indicesBuff(sym_indices);
sycl::buffer best_symsBuff(best_syms);
sycl::buffer LpBuff(Lptemp);
// device selection
cl::sycl::ext::intel::fpga_emulator_selector d_selector;
// queue declaration
cl::sycl::queue q(d_selector);

q.submit([&](sycl::handler& h)
{

sycl::accessor sym_indicesAccess(sym_indicesBuff, h, sycl::read_only);
sycl::accessor best_symsAccess(best_symsBuff, h, sycl::read_only);
sycl::accessor LpAccessor(LpBuff, h, sycl::read_write);

q.single_task([=]() {

for (int i = 0; i < 7; i++)
{
LpAccessor[i] = best_symsAccess[i] + sym_indicesAccess[i];
}
Sample1 object;
object.trial();
});
});

}

Hi,

Thanks for posting in Intel Communities.

In sample2::trails3() function, could you please change the q.single_task() to h.single_task() in sample2.cpp. After changing it to the handler(h) instead of a queue(q), it works fine without any error as shown in the screenshot.

Could you please try at your end? If this resolves your issue, make sure to accept this as a solution. This would help others with a similar issue. Thank you!

Thanks & Regards,

Hemanth.
