Managing the complexity of lookahead for LU factorization with pivoting
We describe parallel implementations of LU factorization with pivoting for multicore architectures. Implementations that differ in two different dimensions are discussed: (1) usin...

Factorizing complex symmetric matrices with positive definite real and imaginary parts
Complex symmetric matrices whose real and imaginary parts are positive definite are shown to have a growth factor bounded by 2 for LU factorization. This result adds to the classe...

Understanding intrinsic characteristics and system implications of flash memory based solid state drives
Flash Memory based Solid State Drive (SSD) has been called a “pivotal technology” that could revolutionize data storage systems. Since SSD shares a common interface with the t...
