Applications for Measurement and Benchmarking of I/O on Parallel Computers
This application computes Cholesky decomposition for sparse, symmetric
positive-definite matrices. It stores the sparse matrix as panels. This
application performs I/O using synchronous read/write operations.
Input Dataset
To drive this application, we used the skirt matrix from NASA that contains
over 45 million double-precision nonzeros and 45,361 columns for a total of
437 MB. The dataset was stored in 8 files, one per processor.
