Linux for Fabric Attached Memory Emulation

  Browse

The Machine from Hewlett Packard Enterprise is a research prototype of our architecture for the future of computing. The core of this architecture is Fabric-Attached Memory or FAM. But how was software for it developed before the hardware existed?

Fabric Attached Memory Emulation (FAME) provides a script and support files to create a set of virtual machines (VMs). These QEMU images represent a cluster of nodes connected through an emulated memory fabric via the IVSHMEM facility of QEMU. This multi-node setup allows the user to explore software development ideas for this model of computing which we call MDC: Memory-Driven Computing.

This Software Delivery Repository provides pre-built versions of the additional pieces necessary to construct a Fabric Attached Memory Emulation using an existing Linux Debian "stretch" or Ubuntu 16 distribution. The emulation configuration script mentioned above relies on this repo. This repo also provides packages for two more use cases:

ARM64 binaries for The Machine prototype
The nodes of actual instances of The Machine are based on ARM processors. This repo provides ARM versions of the amd64 Debian packages (used by FAME) for use on The Machine.
FAM on SuperDome Flex
HPE SuperDome Flex supercomputers have the ability to connect independent partitions via a global address space. This feature can be used as a surrogate "fabric" highly similar to that found in The Machine. amd64 packages in this repo are also used in this FAM (as well as FAME).

All of the sources for this software are maintained in the GitHub Fabric Attached Memory project, please refer to that for documentation and other details.

The packages in the repo were built under the control of one Docker container, l4fame-build-container. The repo was constructed and harvested from another container, l4fame-repo-container.
