Eigen or Lapack matrix inverse

Post by Francois.Saab » 26 Dec 2017 00:05

Hello,

I have a couple of questions:

I followed your git manual on how to install olca-eigen on the github site.

I am trying inverting the matrix A(tech matrix). But i am getting performances like near 10 min. for A( 10,000 x 10,000)

I am wondering if you are getting the same performance or i am missing some installation like ( MPI,or some fortran config) to make the computation in parallel?

i see the matrix inverse is used when calculating LCIA? but LCIA openlca is fast.

is the matrix inverse called when creating he system?

Hello and welcome,
I am not sure I understand, why do you want to conduct the computation in parallel?
Best wishes,
Andreas
