I am in need of a routine that can read a very large matrix from an external file and distribute across a processor grid for use with various pblas routines.
Typically this matrix would be too large to store on a single node prior to redistribution so could someone explain:
(1) if the PDLAREAD routine can read from a file and redistribute without constructing the full matrix on a single node prior to redistribution?
(2) which file format is expected for the input matrix i.e. unformatted or formatted file formats?
Thanks in advance,

I am wondering if you have found a solution to your query, as I am trying to do the same thing now, trying to read a very large matrix that is
saved into multiple files, trying to read it into multiple matrices. Any hint will be greatly appreciated. Thank you. Sara.
