Nimbic VP of Engineering Dr. Don MacMillen to Present Paper on "Electromagnetics Simulation using HPC in a Cloud"

MOUNTAIN VIEW, CA – Wednesday, April 4, 2012 – Nimbic, the leading provider of Maxwell-accurate, 3D Full-Wave Electromagnetic Integrity solutions, today announced that Dr. Don MacMillen, Vice President of Engineering, Nimbic, will present a paper titled “Electromagnetics Simulation using HPC in a Cloud” at EDPS 2012 Symposium in Monterey, California.

Several developments contribute to an increasing need for electromagnetic simulation of large chip ‐ package – board systems. First, the relentless march towards higher integration coupled with increased speeds, particularly for mobile devices. Second, packaging, in particular 3DIC technology is emerging as a major way to provide adaptability for speed and density while reducing power and form factor. Electromagnetic simulation is necessary to ensure design integrity of these large systems, requiring considerable computing resources. While High‐Performance Computing fits this bill, a more cost effective alternative is the use of large numbers of commodity computers, available for example in public and private clouds.

This paper presents the use of MPI (Message Passing Interface) on a cluster of computers connected by fast Ethernet for electromagnetic simulation of complex chip-package-board systems. An iterative boundary element method solver with matrix compression allows minimizing the communication among computer nodes, and facilitates static load balancing across the nodes. Matrix setup can be performed without communication among the nodes, as well as predictive load balancing based on accurate estimates of the compression efficiency.

The iterative solver itself only requires limited data transfer to collect matrix-vector products and to broadcast vectors for successive iterations. The electromagnetic simulator was implemented in the AWS cloud (Amazon Web Services). The paper ends presenting results that show scaling of both speed and memory (i.e. pooling the memory of all nodes in the cluster to act like one large memory) for clusters with up to 10 computers, each with 8 cores.
