Thanks for sorting this out. I'll note the limitation.

Thanks also for explaining the u_host matter as well. I'll put the !$acc statements back in, then.

How do I get the compiler to tell me that, for instance, it is copying back to the host? -Minfo=accel does not seem to give any information on this and there did not seem to be a suitable option for either -Minfo or -Mcuda.

Thanks,

Alistair.
