The Extreme-scale Scientific Software Stack (E4S)

• Sameer Shende (University of Oregon)

Room: Online The [Extreme-scale Scientific Software Stack (E4S)][1] is a curated, Spack based software distribution of 100+ HPC and AI/ML packages. E4S, an HPSF project, is a platform for product integration and deployment of applications such as Quantum Espresso, OpenFOAM, LAMMPS, performance evaluation tools such as TAU, HPCToolkit, DyninstAPI, PAPI, numerical libraries such as Trilinos, PETSc, runtime systems such as Kokkos, MPICH, OpenMPI, RAJA, and supports both bare-metal and containerized deployment for CPU and GPU platforms. E4S provides a Spack binary cache and a set of base and full-featured container images with vendor runtimes to support GPU architectures from NVIDIA, Intel, and AMD. E4S is a community effort to provide open-source software packages for developing, deploying, and running scientific applications and tools on HPC platforms. It has built a comprehensive, coherent software stack that enables application developers to productively develop highly parallel applications that effectively target diverse exascale architectures. ParaTools Pro for E4S(TM) supports commercial cloud platforms, including AWS, GCP, Azure, and OCI and supports Torque and SLURM schedulers. Torque integration uses Adaptive Computing’s Heidi AI ODDC platform for launching images. The tutorial will feature hands on usage on cloud platforms. [1]: https://e4s.io
