[sage-devel] Some sparse matrices cleanup and question on parallelism

2017-10-29 Thread Travis Scrimshaw
Hey all, I'm digging through the (sparse) matrix code right now as I have some ~67000 x 67000 square sparse matrices over QQ(q) (given as the fraction field of ZZ[q]) and the bottleneck in my computations are solving kernels (which isn't too bad, takes about half a day) and taking an inverse.
