Just noticed that since 0.1.0
, gemmt
is introduced while upstream has ≥0.8.0
as requirement.
Hence I should tag the current HEAD
as 0.2.0
and make this roadmap 0.3.0
.
from blis.jl.
And another thing:
- Overriding
gemm!
alone seems forwarding generic strides but not mixed precision. I'd be good to also override somehowmul!{A::Array{TA},B::Array{TB},C::Array{TC}}{TA≠TB≠TC}
for mixed precision support.
cf. log:
# Generic striding is good:
julia> @benchmark view(A, 1:2:1000, :)*B setup=(A=rand(Float64, 1000, 1000); B=rand(Float64, 1000, 1000))
BenchmarkTools.Trial: 22 samples with 1 evaluation.
Range (min … max): 228.803 ms … 233.134 ms ┊ GC (min … max): 0.00% … 0.00%
Time (median): 229.311 ms ┊ GC (median): 0.00%
Time (mean ± σ): 229.954 ms ± 1.277 ms ┊ GC (mean ± σ): 0.00% ± 0.00%
julia> using BLIS; @benchmark view(A, 1:2:1000, :)*B setup=(A=rand(Float64, 1000, 1000); B=rand(Float64, 1000, 1000))
BenchmarkTools.Trial: 213 samples with 1 evaluation.
Range (min … max): 20.919 ms … 21.676 ms ┊ GC (min … max): 0.00% … 0.00%

# Mixed precision not reaching BLIS directly:
julia> A=rand(Float64, 1000, 1000); B=rand(Float32, 1000, 1000);
julia> using Cthulhu; @descend A*B
...
%7 = invoke copyto_axcheck!(::Matrix{Float64},::Matrix{Float32})::Matrix{Float64}
%8 = invoke gemm!(::Char,::Char,::Float64,::Matrix{Float64},::Matrix{Float64},::Float64,::Matrix{Float64})::Matrix{Float64}
