Also, such tools are partially ready and are waiting for the deployment of new exascale class supercomputers,
The ExaSky project is overseen by scientists at Argonnenational laboratory. It is believed that this is one of the most important applications in the field of earth and space science, which will be solved with the launch of exascale supercomputers. An important aspect of the new platforms will be the emphasis on GPU computing. Therefore, the ExaSky project code is actively adapting to work on Intel, NVIDIA and AMD GPUs.
Understanding the accelerating expansion of the Universe is one of the scientific questions that the ExaSky team is committed to exploring.
Observations of the Universe confirm thatit expands, and the speed of its process increases with time. Its main cause has not been clarified; scientists suggest that hypothetical dark energy is responsible.
Cosmic acceleration and others like itThe discoveries were made possible by several advances in observational science combined with improved theory and modeling. The current model of cosmology, which includes dark energy and dark matter (a form of matter that gravitationally interacts in a normal way but has very weak interactions, if any, with atomic matter), provides a very good description of astronomical and cosmological observations. Minor differences do exist. Scientists are not sure whether these discrepancies indicate new physics or are the result of measurement artifacts. As we know, cosmological measurements are often complex and difficult to obtain and measure.
New supercomputers of exascale class will givethe ability to incorporate more sophisticated physics given a wide range of inputs such as massive neutrinos, star and galaxy formation models, and multiple sources of astrophysical feedback such as active galactic nuclei, galactic winds and supernova explosions. These events will be included in both codes and will work on larger, higher resolution meshes.
