      Evan Pretti authored
      * Make reference/CPU minimizer into a kernel
      
      * Add per-platform support for GPU minimization
      
      * Initial implementation of GPU minimization
      
      * Fixes
      
      * Increase robustness when initial gradient is huge
      
      * Handle overflow leading to non-finite values gracefully
      
      * Handle large forces in single precision more robustly
      
      * Optimize kernels
      
      * Fix kernel launch size
      
      * Update banner years
      
      * Don't create MinimizeKernel until first minimization requested
      
      * Make some compile-time constants into kernel arguments
      
      * Consolidate scale calculation kernel
      
      * Condense alpha/beta reduction kernels using atomics
      
      * Condense line search dot kernels with reductions
      
      * Remove a download, and download grad norm separately
      
      * Asynchronously check lbfgs convergence condition
      
      * Restructure line search to avoid download waiting
      
      * Start line search preemptively in case CPU evaluation is not needed
      
      * In rare cases, constraint error might not decrease after one optimization round
      
      * Better handling of unsupported 64-bit atomics, use FLT_MAX
      
      * Pick gradient mode based on GPU vs. CPU evaluation
      
      * Rework getDiff/getScale reduction, remove reduceBuffer
      
      * Older CUDA might not like float hex literals
      
      * Fix error in a comment
