The strength of CALCioM: reducing I/O cross-application contention April 17, 2014

A major challenge in high-performance computing systems is reducing I/O interference between concurrent applications. Allowing two concurrent applications equal sharing of throughput may seem fair, but it can lead to both applications being slowed. Similarly, taking application size into consideration is not enough: interference also varies according to each application’s behavior. 

Searching for the Compressed Spectrum of Natural Supersymmetry
In this talk I will outline the regions of Natural Supersymmetry that are still viable after the 8TeV LHC. In these regions of parameter space the Higgsinos are the lightest supersymmetric states with GeV scale mass splittings. I will show that such compressed states can be probed at the LHC in the channel.

Higgs Boson Physics and LHC Phenomenology in an Inverted Hierarchy Flavor Symmetry Model
The LHC phenomenology of a low-scale gauged flavor symmetry model with inverted hierarchy is studied. A new scalar (a flavon) emerges with mass in the TeV range along with a new heavy fermion associated with the standard model top quark. After verifying the constraints from electroweak precision observables, we investigate the influence of the model on Higgs boson physics notably its production cross section and decay branching fractions. Limits on the flavon from heavy Higgs boson searches at the LHC at 7 and 8 TeV are presented.
Direct Searches for Dark Matter: How Close Are We?
We will review the landscape of this active field of research, covering both recent hints of possible detection, and negative results. I'll try to communicate the many difficulties we presently encounter when attempting to pinpoint a common origin for the several observed anomalies, or assessing their tension with existing exclusion limits.
From Nano to Cosmo: the Discovery of Gravitational Waves from the Big Bang
A tremendous excitement has been generated by the recent announcement of the discovery of primordial gravitational waves through their unique signal imprinted on the polarization of the Cosmic Microwave Background (CMB) radiation. If confirmed, this discovery opens a door to a brand new area of scientific investigation that has the promise to vastly expand our understanding of the Cosmos, our origins, and our understanding of the fundamental forces.
Getting Your Research Published
“Getting Your Research Published – Hints and Policies” will be the topic of a JumpStart meeting Thursday, April 24, at 12:30 p.m. in the Building 213 Cafeteria Private Dining Room. All are welcome to attend — bring your lunch and a friend.

Yvette Woell (CIS) will offer hints designed to help researchers negotiate the scholarly publishing process while adhering to Argonne-specific policies surrounding the publication of scientific and technical information.
