The

local_mem_size

in SYCL is not a complete equivalent of

sharedMemPerBlock

. You may need to adjust the code.

In CUDA*, the

sharedMemPerBlock

reports the size of the shared memory in bytes available per block. The SYCL* equivalent of a CUDA block is a work-group. The SYCL equivalent of shared memory is local memory. There is no limitation on the size of the local memory per work-group in SYCL. There is a limit on the maximum size of the local memory in bytes available per compute unit, which is exposed by the

info::device::local_mem_size

device descriptor in SYCL.

Verify the code correctness.
