-> As a leader in high-performance computing, Lawrence Livermore wields a large portion of the Department of Energy’s HPC resources to advance national security and foundational science. The Sierra supercomputer supports the National Nuclear Security Administration’s Stockpile Stewardship Program by enabling more accurate, more predictive simulations. This generation of computers is known as heterogeneous, or hybrid, because their architectures combine graphics processing units and central processing units to achieve peak performance well above 100 petaflops. (A petaflop is 10^15 floating-point operations per second.) The next generation’s processing capability—at least an exaflop (10^18 flops)—will be many times greater. HPC software must adjust to these new hardware standards. As the exascale era begins, two major initiatives leverage and expand Livermore’s HPC capabilities, with a spotlight here on software. The [Exascale Computing Project](https://www.exascaleproject.org/), a joint effort between the DOE Office of Science and NNSA, brings together several national laboratories to address many hardware, software, and application challenges inherent in the organizations’ scientific and national security missions.

-With software development underpinning much of LLNL’s mission-driven science, the Lab’s developer community has a long history of figuring out solutions to a huge number of complex challenges. But how do we know what’s working and what isn’t? What tools or other support do developers need to do their best work? The [RADIUSS project](https://software.llnl.gov/radiuss/) team conducted a survey of LLNL developers in late 2022 to assess their happiness and needs, both for awareness and targeted action that might be pursued in the next year. Some of this insight has been published publicly for the purposes of knowledge sharing and community building.
