LU Decomposition


This application computes the dense LU decomposition of an out-of-core matrix [1].
This application performs I/O using synchronous read()/write() operations.

Input Dataset

To drive this application, we used an 8192 x 8192 double precision matrix
(total size 536 MB) with a slab size of 64 columns.


See above.
