I don't think this kernel (actually any of those kernels) supports half yet.

[benbarsdell]

I think this was fixed in https://github.com/ledatelescope/bifrost/commit/d688b51093095864001b911322a0e5eafea8f2a5, can you confirm?

[gijzelaerr]

Sorry for the delay, but yes, this seems to be resolved. Thanks!
