You misunderstood, we are not going to distribute Sage linked to MKL. This is obviously not legal to distribute. But it should be possible for you to compile Sage with alternate BLAS implementations on your own machine if you chose to. On Sunday, August 31, 2014 10:53:49 PM UTC+1, Fernando P

It is because your first curve E1 is not a minimal model. Its label is still successfully given ('7161g1') but when you construct the curve from that label it gives you the minimal model. Compare discriminants: that of E1 is 2^12 times that of E2. I am copying to sage-support and sage-nt, eithe

Hi. Recently I am doing some computation of Manin constants of elliptic curves. But, as you can see in the attached file, when I defined the same curve in two different ways, i.e., by specifying coefficients and by giving the label of the curve, sage gives two different Manin constants. I am r

How do you deal with OpenBLAS not supporting fork? They use OpenMP and the gcc implementation does not allow fork(), at least for now. If you use OpenBLAS before forking, then your program will deadlock in OpenBLAS after the fork. On Friday, August 29, 2014 10:55:32 AM UTC+1, François wrote:
