3090 Issues

[graffitilogic]

Running on a 3090 (either the release on github or through my own local build) -

Kangaroo exits prematurely, without an error after Creating Kangaroos...

I thought it might be b/c of the lack of an 82 x 128 entry in GPUEngine.cu - so I tried to add one ( { 0x82, 128 }
Didn't seem to help. If I use the sSMtoCores loadout that is in the original Kangaroo repo (where it stops at 0x75) - it will run but it shows unfeasible speeds at [346224215.44 MK/s][GPU 346224109.10 MK/s][Count 2^53.43] and the memory allocation looks incredibly low at [2.0/4.0MB]. Also notice the 82x0 sm/core calc - Regular Kangaroo does this as well.

Any thoughts what might be happening here? I can built pretty easily if you want me to try anything. Thanks for putting in the effort to 256-enable Kangaroo.
