This video provides a quick overview of the AXIOM Software stack. The AXIOM project provides the possibility to make a high performance computing (HPC) cluster on top of small embedded boards based on Xilinx Zynq ultrascale+. We use the fast transceivers ofnthe FPGA in order to provide fast remote DMA (RDMA) between boards.
The programming model is a uniform programming model based on OpenMP and OmpSs@Cluster.
The demo shows the AXIOM software stack emulated using QEMU Zynq FPGA virtual machines. The AXIOM Network interface (AXIOMNIC, or AXIOM-link) is emulated as well using an external switch process.
The demo shows the startup of the network, a few utility programs, and two demos (a matrix multiply and a NBody simulation). The demos are compiled with the Mercurium compiler, and then executed on the emulated cluster. Finally, execution traces collected with Extrae are merged and dissplayed using the PARAVER viewer.
The virtual machines used in this video are available open-source on the website of http://www.axiom-project.eu/
