### Parallel SVD computation

Posted:

**Mon Aug 21, 2017 10:25 am**Hello guys.

I would like to start using ScaLAPACK for the parallel SVD computation.

I was looking into the TESTING/EIG/pdsvd* examples. I was wondering how one fills in the actual matrix. I could not find any reading routines. Is it solely user's responsibility to read whatever matrix representation and then fill in the data structures in ScaLAPACK? Could you please refer me to where the data for the tests is taken from? Maybe somebody has concrete examples of reading the data, computing SVD for rectangular matrices in parallel?

Thank you, I appreciate your answer.
