"CfA astronomers Rafael Martinez-Galarz and Howard Smith and their two colleagues have developed a new statistical analysis technique to address the problem of confused SEDs in clustered environments. Using the highest spatial resolution images for each region, the team identifies the distinguishable stars (at least this many are in the cluster) and their emission at those wavelengths."

Revisiting the Six City Study
"Last June, eight new Harvard-affiliated researchers revisited the study, using new technologies and innovations in statistical analysis and examining Medicare data—the largest and most public dataset available documenting the health of U.S. citizens—thus presumably averting renewed charges of secret science (an issue raised anew by current EPA administrator Scott Pruitt). Their findings breathe new life into the main conclusion…
Mapping Invisible Ocean Pollutants
Prof. Elsie Sunderland's lab seeks to build a picture of pollutants which threaten our oceans. “People struggle with this idea that we could impact planetary level processes. But we do. There’s irrefutable evidence on many, many scales that we’re changing the natural functioning of these ecosystems.” Read more in Harvard Magazine's full story
Service Center & Billing FAQ
FAS Research Computing has moved storage and compute services to a cost model in order to meet the demands of our userbase which includes labs outside of the FAS. Having the same cost structures across all of the Schools/Institutes at Harvard will allow FASRC to be better aligned to a number of regulations and requirements. Most of the schools are…
Odyssey 3 Upgrade Complete (June 2018)
As of May 22nd 2018, the new Odyssey 3 cluster is fully operational. All login nodes and compute nodes* on the Odyssey cluster are running CentOS 7, have CentOS 7 modules, and the ability to use Singularity containers enabling you to build specialized software for yourself. Please see our updated/additional documentation, including: CentOS 7 Transition FAQ Running Jobs Singularity on Odyssey…
New compute and partition reconfiguration
Fall greetings from RC! We are very pleased to unveil the new compute purchased by FAS as part of the Odyssey 3 project (https://www.rc.fas.harvard.edu/odyssey-3-the-next-generation/). This new compute hardware has been benchmarked at 0.5 petaflops, making it the fastest block of compute to date at Harvard. This hardware is now available on the cluster for people to use in these new…
Accelerating Viscoelastic Calculations
Read more about how Brendan Meade's group used machine learning and the Odyssey cluster to accelerate large-scale viscoelastic calculations using neural net concepts at Harvard Magazine. Earthquakes Around the World - Harvard Magazine For a deeper dive, you'll find their paper describing the work at https://arxiv.org/abs/1701.08884 ABSTRACT: "One of the most significant challenges involved in efforts to understand the effects of repeated…
Odyssey Updates
Research Computing Odyssey Users, For those of you returning, welcome back. For those new to Harvard, we hope to provide you with solid services, resources and support. Below is information on some important updates as well as our new training schedule. Next Maintenance: Due to the Labor Day holiday, the next monthly maintenance will be Monday, Sept. 11th 7-11am. A…
Odyssey 3 Announcement
Greetings Odyssey cluster users. We'd like to let you know that we are planning several major updates to the Odyssey cluster that will be rolling out over the next few months. This third generation of high performance computing will include increases in raw compute power, a new CentOS 7-based application stack, and the introduction of the Singularity container system. We…
Air Pollution and Mortality in the Medicare Population
ABSTRACT - We constructed an open cohort of all Medicare beneficiaries (60,925,443 persons) in the continental United States from the years 2000 through 2012, with 460,310,521 person-years of follow-up. Annual averages of fine particulate matter (particles with a mass median aerodynamic diameter of less than 2.5 μm [PM2.5]) and ozone were estimated according to the ZIP Code of residence for…
