[en] We show performance results executing the FEniCS Project finite element
software on Amazon Web Services (AWS) c7g and c7gn instances with Graviton3
processors. Graviton3 processors implement the ARMv8.4-A instruction set and pro-
vide Scalable Vector Extensions (SVE) for Single Instruction Multiple Data (SIMD)
operations. Comparing clang 18 and GCC 13 series compilers for compiling an FFCx
generated high-order Laplace finite element kernel our results show that both com-
pilers emitted automatically vectorised loops with fused multiply-add instructions
on SVE registers. The AWS c7gn instances include a Elastic Fabric Adaptor (EFA)
interconnect with a bandwidth of 200 GB s 1 for low-latency and high-bandwidth
communication. We tested multi-node weak scalability of a DOLFINx Poisson solver
up to 512 MPI processes. We find the overall performance and weak scalability of
the c7gn-based cluster is similar to a dedicated AMD EPYC Rome x86-64 cluster
installed at the University of Luxembourg.
