As a user of a program that uses kokkos, I ran into this error message this morning and had no idea what it was or what it meant:

Kokkos::HostSpace::allocate[ INTEL_MM_ALLOC ]( 18446743565090964400 ) FAILED NULL

We figured out it was because the requested array was too large. Can you please make this error message more useful? Maybe the name of the array that is trying to be malloc'ed?

Do we have an ETA for when a fix for this will get in?

Hopefully #2409 should address this. We probably still need Cuda versions of this same kind of thing, so I'm leaving the tag [WIP] on here for now.
