CRAM SEU detection and mitigation support with OpenCL/oneAPI

Hi there, I'm doing a large and long-running FPGA supercomputing project, with an average of 20 FPGAs running in parallel over the course of 5 months. Our project is very sensitive to cosmic ...

Yeah I do think M20K + CRAM together should cover most of them.

The one thing I'm looking for is documentation on this function:

clSetDeviceExceptionCallbackIntelFPGA(
    cl_uint                   num_devices,
    const cl_device_id *      devices,
    CL_EXCEPTION_TYPE_INTEL   listen_mask,
    void (CL_CALLBACK *       pfn_exception_notify)(
        CL_EXCEPTION_TYPE_INTEL   exception_type,
        const void *              private_info,
        size_t                    cb,
        void *                    user_data),
    void *                    user_data);

Specifically if the listen mask is inclusive or exclusive.
Which inputs allow me to receive ALL error signals?

I've not found any documentation on it. Could you perhaps get me in touch with one of the developers of the Intel OpenCL library?
