The sizeof() operator returns the size of an object or type in bytes, not bits. Instead of calculating the number of bits using, e.g., CHAR_BIT * sizeof(), hard-code 64 since it is close to the declaration. This is a prerequisite for HBM support with up to 32 channels.

Replace manual memory allocation using new[] and delete[] with std::vector, which avoids unintended memory leaks. Drop unneeded vectors for per-thread promise and tg_exe, which may be stored as local variables inside the lambda function. The lambda is declared as mutable to permit moving the promise.
