`peakflops` not showing any difference with loading `AppleAccelerate` #65

Closed jamblejoe closed 7 months ago

jamblejoe commented 8 months ago

see e.g.

julia> peakflops(4096)
6.095799831981197e10

julia> using AppleAccelerate

julia> peakflops(4096)
6.073612665240428e10

but calling the explicit functions in AppleAccelerate does seem to work and results in a speed difference

julia> using BenchmarkTools

julia> X = randn(1_000_000);

julia> @btime exp.($X); # standard libm function
  5.061 ms (2 allocations: 7.63 MiB)

julia> @btime AppleAccelerate.exp($X);
  2.003 ms (2 allocations: 7.63 MiB)

peakflops started to work as expected, when I upgraded from 13.0 to 14.1.
