To reproduce

1. Include a code snippet that is as short as possible
2. Specify the command which should be used to compile the program
3. Specify the command which should be used to launch the program
4. Indicate what is wrong and what was expected

Environment

• OS: [e.g Windows/Linux]
• Target device and vendor: [e.g. Intel GPU]
• DPC++ version: [e.g. commit hash or output of clang++ --version]
• Dependencies version: [e.g. the output of sycl-ls --verbose]

Additional context

[cperkinsintel]

This fpga_pipe.cpp test has been passing because it was using the wrong binary operation to fold together test results. I fixed this in this and some other tests recently. My PR passed the CI because, apparently, we don't have exercise the FPGA accelerator (or emulator) there.

fpga_pipe.cpp tests 12 different combinations, the last two ( test_array_th_nb_pipe and test_array_th_bl_pipe ) are failing. Rather than disable the entire test, I'm going to just disable those two and open a ticket for them.

[cperkinsintel]

@KornevNikita - The PR that disables the two failing cases has been merged and a JIRA opened for them. This test should be passing in post-commit testing now. Is it OK to close this GitHub issue?

[KornevNikita]

@cperkinsintel I don't mind, but I guess this should contain jira number rather than link to this issue.

@cperkinsintel I don't mind, but I guess this should contain jira number rather than link to this issue.

GH issues are preferrable as everybody has access to them.

GH issues are preferrable as everybody has access to them.

Agree, but it would be strange to link the closed issue. I assume it normally means the root cause was fixed. I guess we should have a jira number with some comment at least here, or just let it be opened.
