HPCU Bi-Weekly Challenge - Hybrid Parallel Rumor Mill


November 24, 2014


Hybrid Parallel Rumor Mill


This problem challenges you to create a hybrid MPI+OpenMP model of a rumor spreading through a population.


The model in this problem is based on Shodor's Rumor Mill system dynamics model (http://shodor.org/talks/ncsi/vensim/RumorMill.html). You may find it helpful to reference that model as you solve the problem.

This challenge problem is also similar to six previous "Hy...

Earth’s Magnetic Field Could Flip Within a Human Lifetime

UC Berkeley

It’s not as bizarre as it sounds. Earth’s magnetic field has flipped – though not overnight – many times throughout the planet’s history. Its dipole magnetic field, like that of a bar magnet, remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens and, presumably over a few thousand years, reverses direction. Left to right, Biaggio Giaccio, Gianluca Sotilli, Courtney Sprain and Sebastien Nomade sitting next to an outcrop in the Sulmona basin of the Apennine Mountains that contai...

New Records Set for Silicon Quantum Computing

University of New South Wales

Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits" -- the building blocks for quantum computers -- that each process quantum data with an accuracy above 99%. The two findings have been published simultaneously today in the journal Nature Nanotechnology. "For quantum computing to become a reality we need to operate the bits with v...

NASA to Highlight Mission Advances Enabled by Supercomputers at SC14

From our home planet to the far reaches of space, NASA will highlight science and engineering mission advances enabled by agency supercomputers at SC14.  Inside the NASA exhibit, presenters will unveil on a 10-foot-wide hyperwall stunning new high-definition movies showing:

  • Unprecedented global maps of the ocean and sea-ice incorporating four years of observational data to address questions such as how our ocean takes up and releases heat;
  • A massive two-year “Nature Run” simulating Earth’s weather at local scales much finer than the highest-resolut...

Programming Computers in Everyday Language

Karlsruhe Institute of Technology

Computers speak a language of their own. They can only be programmed by those, who know the code. Computer scientists of Karlsruhe Institute of Technology (KIT) are presently working on a software that directly translates natural language into machine-readable source texts. In this way, users may generate own computer applications in a few sentences. The challenge to be managed is that people do not always describe processes in a strictly chronological order. A new analysis tool developed by KIT researchers serves to automatically order ...

Anne Condon: Computer Scientist. Passionate Academic. Triathlete.

Tech Republic

Women were far more well represented in computer science when Anne Condon first decided in high school the subject sounded interesting, despite never having used a computer. Decades of theoretical computer science work later, Condon, who now serves as head of the computer science department at the University of British Columbia, is dedicated to helping young women find their way in the field. Condon joined the Computing Research Association's Committee on the Status of Women in 1994 and for three years before her term ended in 2007, she headed a project to...

Towards Big Data Computing at Extreme-Scales


Former Computing Community Consortium (CCC) Computing Innovation Fellow (CI Fellow), Dr. Ioan Raicu, now an Assistant Professor in Computer Science at Illinois Institute of Technology (IIT) and a research faculty member in the Math and Computer Science Division at Argonne National Laboratory, focuses on the relatively new distributed systems paradigm called Many-Task Computing (MTC). MTC aims to bridge the gap between two predominant paradigms, namely High-Throughput Computing (HTC) and High-Performance Computing (HPC). His work has focused on defining and explor...

Tapia 2015 Registration is Now Open

Registration is now open for the 2015 Richard Tapia Celebration of Diversity in Computing Conference, scheduled for February 18-21, 2015 in Boston, Mass.

The goal of the Tapia Conferences is to bring together undergraduate and graduate students, faculty, researchers, and professionals in computing from all backgrounds and ethnicities to:

  • Celebrate the diversity that exists in computing;
  • Connect with others with common backgrounds, ethnicities, disabilities, and gender so as to ...
