Classes
struct	batchlas::ops::gemm::Direct
	gemm_direct: one work-item per element, any form; max_wg >= 64 More...
struct	batchlas::ops::gemm::Tiled
	gemm_tiled: 16x16 shared-memory tile, any form; max_wg >= 256 More...
struct	batchlas::ops::gemm::Small
	gemm_small: several matrices per work-group; real, see small_fits More...
struct	batchlas::ops::gemm::Reg
	gemm_reg, float only: m x n x k macro tile with k unroll u; must name a reg_configs entry that instantiates the call's transpose form, and max_wg must cover its threads(). More...
struct	batchlas::ops::gemm::Wide
	gemm_wide, every scalar: 16-byte-granule m x n x k tiles; must name a wide_configs entry that instantiates the call's form, and max_wg must cover its threads(). More...
struct	batchlas::ops::gemm::Vendor
	backend::gemm_vendor; needs the level-3 library More...
struct	batchlas::ops::gemm::Forms
	Transpose forms an instantiation exists for, after the real-scalar C->T fold. More...
struct	batchlas::ops::gemm::RegCfg
	One compiled register config: tr/tc thread tile, stages, the forms instantiated, and whether NN takes the unpredicated leg when the layout allows (derived per call, never a gate). More...
struct	batchlas::ops::gemm::WideCfg
	One compiled wide config. More...
