without umfpack, it takes 950+ seconds, with umfpack it takes 700+ seconds. how do i know that umfpack is working properly?? and why not we're using gotoblas2 along with umfpack????
Yes, that could be the problem. I use ATLAS and have numpy, scipy, umfpack etc. built against it. SfePy itself uses BLAS only through those packages, not directly.
I have heard that gotoblas is really good, but have no personal experience with. ATLAS should be fine as well, just anything better then the reference blas implementation numpy uses by default.
Can you post here the assmebling solution times of, for example:
./runTests.py tests/test_input_navier_stokes.py --debug
One iteration is enough, they should be similar. My times are:
sfepy: rezidual: 0.04 [s] sfepy: solve: 0.72 [s] sfepy: matrix: 0.36 [s]
