Graph 500 is an established set of large-scale benchmarks for data intensive applications and these high-performance applications cannot be improved without a meaningful benchmark. Graphs are a core…
We propose a new algorithm to improve the strong scalability of right-looking sparse LU factorization on distributed memory systems. Our 3D algorithm for sparse LU uses a three-dimensional MPI…
Non-negative matrix factorization(Nmf) is an important tool in high-performance large scale data analytics with applications ranging from community detection, recommender system, feature detection…
We present a novel distributed memory algorithm to improve the strong scalability of the solution of a sparse triangular system. This operation appears in the solve phase of direct methods for…
The last few decades have witnessed a significant increase in the sophistication of scientific instruments. This sophistication has led to an exponential increase in scientific data, so much so that…
