the Xeon Phi does only support the following extensions: cl_khr_icd cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_byte_addressable_store cl_khr_spir cl_khr_fp64
That means we are not able to use 64-bit atomic operations. Is there any possibility to use atomics for 64-bits? (cl_khr_int64_base_atomics)
That is absolutely necessary for many scientific applications, because float does not suffices in precision.
