Unhandled exception: queue(cpu_selector)

[Tamer_Assad]

Hi,

Instantiating a queue object using a device_selector object of type cpu_selector results in:

Release:

Unhandled exception at 0x00007FFA6543A839 in AppName.exe: Microsoft C++ exception: cl::sycl::runtime_error at memory location

Debug:

Unhandled exception at 0x00007FFA6609C4C8 (ucrtbase.dll) in AppName.exe: An invalid parameter was passed to a function that considers invalid parameters fatal.

Ref. DPC++ VecAdd example  lines #100

//default_selector device_selector;
cpu_selector device_selector;

queue device_queue(device_selector);

What could cause this error?

Best regards,

Hi Rahul,

This has Occurred on a windows 10 environment,

oneAPI base tool kit : w_BaseKit_b_2021.1.3.085_offline

Thank you for your care.

Best regards,

Also, please note that, the last time I tested that was couple of days ago, and it was working well, but now its not, knowing that no installation has been performed on the target machine since the last successful attempt.

Best regards,

Hi Rahul,

Thank you for your support.

Installing the latest base kit version "w_BaseKit_b_2021.1.4.423" has fixed this problem.
