Iterating over nonzero elements of a GBMatrix sparse matrix

4

Is there any convenient accessor through Julia to iterate over the nonzero elements of a `GBMatrix`, with the full triplet information `(i,j,v)` instead of `v` alone? Similar to the [`SparseArrays`package](https://docs.julialang.org/en/v1/stdlib/SparseArrays/#SparseArrays.nzrange),...

CompatHelper: add new compat entry for KLU at version 0.3, (keep existing compat)

1

This pull request sets the compat entry for the `KLU` package to `0.3`. This keeps the compat entries for earlier versions. Note: I have not tested your package with this...

GBMatrix constructors for transpose and adjoint matrices

2

Since `Transpose{T, SparseMatrixCSC{T}}` and `Adjoint{T, SparseMatrixCSC{T}}` are used as place-ins for CSR matrices, it may be a good idea to add `GBMatrix` constructors for these types, which would directly construct...

Vector dot is much slower than build-in operation

1

I can get decent parallel speed-up for sparse matmul and sparse matvec, but the dot product between two vectors seems very slow: ```julia using SuiteSparseGraphBLAS using BenchmarkTools gbset(:nthreads, 16) b...

How to set the number of parallel threads?

4

The [benchmark section](https://github.com/JuliaSparse/SuiteSparseGraphBLAS.jl#benchmarks) shows faster execution with more threads. However, I cannot reproduce such parallel scaling. The benchmark script: ```julia using Random: seed! using SparseArrays using SuiteSparseGraphBLAS using BenchmarkTools @show...

Many examples should go in a future GraphBLAS.jl, but I'll add some here anyway. - [x] Triangle Counting - [ ] Centrality - [x] PageRank - [ ] Something Boolean?...

new examples added, new files could still contain some print statements used to test the algorithms
