Scalability of turbulent flow simulations on large-scale computers

Argonne Mathematics and Computer Science Division

A fundamental principle of parallel computing is that by subdividing a computation across P processors, one can realize a P-fold reduction in time to solution. For example, a simulation that uses a billion particles or gridpoints can be distributed across two compute nodes and run in half the...

Mira Supercomputer Simulations Give New “Edge” to Fusion Research

Scientific Computing

Using Mira, physicists from Princeton Plasma Physics Laboratory uncovered a new understanding about electron behavior in edge plasma. Based on this discovery, improvements were made to a well-known analytical formula that could enhance predictions of and, ultimately, increase fusion power...

Stable "superoxide" opens the door to a new class of batteries

Argonne National Laboratory

While lithium-ion batteries have transformed our everyday lives, researchers are currently trying to find new chemistries that could offer even better energy possibilities. One of these chemistries, lithium-air, could promise greater energy density but has certain drawbacks as well.
