Hello Margaret

So, your solver idea is for 32 and 64 bit floating point number matrices? 
Here at SageMath we have all kind of rings, so it's always good to state 
this. Hence, I think your project idea is pure numerical mathematics and 
although it's interesting, I'm not sure if we can mentor it. Have you tried 
to find other organizations, that are more into this?

also, how does your idea compare to SuperLU, UMFPACK/SuiteSparse, or other 
approaches mentioned here?
