Revision 96698170814ff8aa4aaecacb5d23bbe2e3a1e17e authored by Andrew Adams on 16 August 2020, 20:54:08 UTC, committed by Andrew Adams on 16 August 2020, 20:54:08 UTC
BGU on CUDA had regressed from its stated performance due to the atomic floating point adds being compiled to CAS loops due to complex indexing expressions diverging on the LHS and RHS of the +=. Inlining less stuff into the += operations makes it succeed again, and the schedule was improved with a few other tweaks. Longer-term we need a first-class way to represent += so that we're not sensitive to this sort of divergence.
