These resource and workflow challenges really called for a fundamental rethinking in software design. A large part of this problem was that the system’s workload managers were rather simple and didn’t provide the necessary capabilities. One system cannot interoperate with another. And this produced a rather unwieldy software ecosystem workflow.

So, indicatively, we already saw back then so many domain-specific workflow managers with a lot of redundant business logic implemented across them to support those emerging workflows. This pattern was created as researchers increasingly embraced much more complex scientific workflows. They were also quickly changing from single MPI jobs to rather complex interdependent jobs and tasks that needed to be managed all together in a highly sophisticated fashion. The other trend was users’ workloads running on HPC systems. The problem would never become any easier if left to chance. The traditional solutions with homogenous compute node- and compute core-centric assumptions were already being increasingly hard-pressed in coping with the so-called heterogeneous hardware environments. Back then, hardware vendors had begun to incorporate various specialized hardware beyond the CPU, which included things like GPUs and burst buffers.

One trend was what I call the resource challenge. Looking forward to the next decades to come, we realized that two of the strongly emerging trends that had just begun to affect HPC workload managers would continue into the decades to come and would negatively affect us to a greater degree. It goes back to nearly eight to nine years ago. Some of the founding members of Flux are actually some of those principal engineers behind these solutions. In fact, Livermore computing has a long history of designing workload managers, such as LCRM and Slurm, which have had a worldwide adoption. We should be modest, but we were pretty qualified to call it. It started when Livermore’s in-house system software experts realized that traditional workload managers in use at Livermore were a bit too brittle for future use. In the beginning, Flux was a very grassroots effort. I would speak to how our Flux project started because this can actually tell a lot about the problems that it is good at solving.

Will you get us going by sharing why Flux was created and by outlining a bit of its history?Īhn: Sure. Gibson: Flux is a software framework that manages and schedules scientific workflows to make the most of computing and other resources and enables applications to run faster and more efficiently. Our topics: Flux’s grassroots origin, benefits, importance to science and engineering, and more. Flux enables science and engineering work that couldn’t be done before.įor the discussion, we’re joined by Dong Ahn, Stephen Herbein, Dan Milroy, and Tapasya Patki of LLNL and the Flux team. This time we delve into a software framework developed at Lawrence Livermore National Laboratory (LLNL), called Flux, which is widely used around the world. Hi, in this podcast we explore the efforts of the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP)-from the development challenges and achievements to the ultimate expected impact of exascale computing on society.
