Test for `[[sycl::reqd_work_group_size]]` exception when mismatched `nd_range` was given #285

andreyromanof · 2022-02-16T01:46:57Z

This PR provides test for optional kernel features.
Test decorates kernel with attribute [[sycl::reqd_work_group_size(N)]] where N is supported size and pass nd_range instance with unsupported size to parallel_for invocation and expect exception sycl::errc::nd_range.

Depend on:

Disable _Pragma to work around Clang 8 bug #296

…nd_range` was given

Some concerns about disabling the test for implementations that don't support these features.

Do you maybe have output from a run of ComputeCpp or is this just to play it safe and not risk breaking CI?

Here output from a run of ComputeCpp before I apply filter. On line 2791 warning messages about unknown attributes, which is why I decided to put test in the filter.

But right now I also noticed other errors like no known conversion from 'cl::sycl::nd_item<1>' to 'sycl::item<1>' on line 2814. Am I wrong with the lambda argument? Do I have to use nd_item<1> instead of item<1> on line 41 in kernel_features_mismatched_nd_range_exception.cpp?

I think it's better to maintain an alphabetical ordering, the same for other filters. Also, should we maybe name it kernel_optional_features?

Sorted lines in this commit: a02a67f.

We can rename it but in other PR when all tests will be implemented, because some of the tests in other PR, some of the tests in development and it will be unhandy to rename these tests now.

IMHO, I think we can keep the current name.

From the spec:

In order to guarantee source code portability of SYCL applications that use optional kernel features, all SYCL implementations must be able to compile device code that uses these optional features regardless of whether the implementation supports the features on any of its devices.

You've marked two implementations in the CI as not passing (adding the test to the filter), but I believe they should be able to pass the test even if they don't implement the features, otherwise they wouldn't be able to pass conformance in the current CTS design.

As I understand CI doesn't run tests, it's just built it. Here you can find output from the building of tests on CI. ComputeCpp and hipsycl failed building due to some errors.

From hipsycl logs, line 1970: error: ‘errc’ is not a member of ‘sycl’. Looks like enum with error codes is not implemented yet and attributes too (line 1966).

Similar situation for computecpp.

But maybe I was wrong when I put these two implementations in the filter because both of them give the error message: no known conversion from 'cl::sycl::nd_item<1>' to 'sycl::item<1>' error, so it can be bug of tests itself.

It was my mistake. I changed to nd_item but now getting another error. Right now investigating it.

Return optional features to filter for hipsycl

I tried to fix the code for the computecpp CI but looks like this implementation has a few specific issues:

It's doesn't support implementation-defined kernel names according to paragraph 4.9.4.2. Link to the error
I changed const auto max_wg_size to const size_t max_wg_size, because otherwise compilation was failed. This variable is used in the constructor of nd_range Link to error
Problem with linkage I was unable to solve, but my guess that its kind of stringify function for the sycl::errc that cause an error.

Changed `testing_wg_size` to 1 that supports by all devices Changed `INFO` to `SECTION`

Build error on ComputeCpp points to SECTION invocation and use of undeclared identifier INTERNAL_CTS_ENABLED_TEST_CASE_BODY. Don't have any more ideas on how to fix it and seems like it is not a compiler bug, so we can't just add the test to filter.

Actually the root cause is the error before that: error: _Pragma takes a parenthesized string literal. I've actually seen this before (it's a bug in Clang 8) and already have a fix for it. I'll open a PR shortly. This will however not really solve the problem at hand, as ComputeCpp then still fails during linking with undefined reference to cl::sycl::detail::errc_to_str[abi:cxx11](cl::sycl::detail::errc) (cc @ProGTX).

The aforementioned bug should be fixed by #296.
