In April 2018, researchers from Goethe University Frankfurt and the Frankfurt Institute for Advanced Studies (FIAS) reported that they had accomplished the first successful three- dimensional simulations of the effects of colliding black holes carried out by using a first-order formulation of the Einstein equations.
Understanding Behaviors in the Extreme Environment of Natural Gas Turbine Generators
Earl Joseph, Steve Conway, Bob Sorensen and Alex Larzelere
Understanding physical behaviors in harshenvironments is extremely hard, and at times,critically important. That is the situation GeneralElectric (GE) engineers faced when designing theirnew heavy-duty gas turbine generator. Gaining even 1% greater efficiency could save their electric utility customers millions of dollars andimprove GE’s world-wide competitiveness. Thekey issues involved a better understanding of the fluid dynamics and reactive flow behaviors in the turbine’s 1,500 degree Celsius combustion chambers and the interactions between the 2 to 16 individual flames in the chambers. GE Power engineers had reached the limits of theory and experiments, motivating them to apply advanced modeling and simulation.

Project Spaceborne: NASA, HPE Team Up to Use Supercomputers for Eventual Journey to Mars
Earl Joseph, Steve Conway, Bob Sorensen and Alex Norton
In August 2017, Hewlett Packard Enterprise (HPE) and NASA embarked on a daring experiment –- blast a supercomputer into space, place it aboard the International Space Station, and see how it functioned amid shifting radiation levels and violent G-forces. Since that time, the project known as Spaceborne has consistently delivered one trillion calculations per second, revolved around the earth at least 4,275 times, and has been described by HPE as a great success that has “exceeded expectations.”
