An out-of-core domain decomposition method (DDM) based on parallel higher-order Method of Moment (MoM) is present, herein referred to as OOC-DDM, for the radiation patterns of electrically large problems. This algorithm allows the matrix be stored on the hard disk when the matrix is too large to fit in the main memory of the computing platform. The using of higher-order basis functions can further...
A traveling waveguide array with 108 narrow-wall slots is analyzed using the parallel method of moments with higher-order polynomial basis functions on a distributed memory cluster. The concept of the perfectly matched layer in differential-equation methods is introduced to design the matched load terminating the waveguide. The simulated data is compared with the commercial software - ANSYS HFSS's...
A newly developed code, TIDES, is run on a high performance computing cluster for complicated EM problems. TIDES has the capability to exceed the memory limitations of typical computer systems by using the method of moments with higher-order basis functions and a parallel out-of-core solver. In 2008, TIDES solved an MoM problem with half a million unknowns using only 320 GB RAM and 4 TB of hard disk...
In this paper, a newly developed code, TIDES, is run on four high performance computing clusters. TIDES has the capability to exceed the memory limitations of typical computer systems by using the method of moments with higher order basis functions and a parallel out-of-core integral equation solver. The new results presented here show that TIDES is an excellent tool for solving challenging electromagnetic...
Currently, the problem size that can be solved by the method of moments (MoM) is limited by the amount of RAM installed on the computer. To reduce number of unknowns for MoM, a higher order polynomial function is introduced in this paper as the basis function. To further extend the capability of the MoM code, this paper also describes a newly developed out-of-core solver based on PLAPACK which breaks...
Technological advances enable modern processors to utilize increasingly larger DRAMs with rising access frequencies. This is leading to high power consumption and operating temperature in DRAM chips. As a result, temperature management has become a real and pressing issue in high performance DRAM systems. Traditional low power techniques are not suitable for high performance DRAM systems with high...
