Oh, I cut SciML/SciMLBenchmarks.jl#91 a little too aggressively.
Mx = Tridiagonal([1.0 for i in 1:N-1],[-2.0 for i in 1:N],[1.0 for i in 1:N-1])
My = copy(Mx)
from sparsedifftools.jl.
what are Mx and My here?
from sparsedifftools.jl.
For the record, recorded 600 seconds initially (otherwise I'll forget and have to recompute it)
julia> @time colorvec = matrix_colors(jacsparsity)
683.859562 seconds (1.10 M allocations: 121.140 MiB, 0.01% gc time)
from sparsedifftools.jl.
It's the whole matrix to graph function which is slow, the rest can wait:
julia> @time matrix2graph(jacsparsity, false)
475.198843 seconds (719.90 k allocations: 100.197 MiB, 0.01% gc time)
from sparsedifftools.jl.
two potential speedups already: dropzeros
should be the inplace version, the non-inplace currently used returns a value that is ignored
from sparsedifftools.jl.
since the indices are known, @inbounds
should be used throughout the function
from sparsedifftools.jl.
#94 is a first take on that, I think there may be a way to improve this even more
from sparsedifftools.jl.
