Message #01659
heterogeneous instance types
I've uploaded a family of related of blueprints that the USC-ISI team is hoping to integrate into the Diablo release:
https://blueprints.launchpad.net/nova/+spec/heterogeneous-instance-types
http://wiki.openstack.org/HeterogeneousInstanceTypes
They could use some reviews in advance of the design summit. At our internal sprint review this week, we were able to launch in a multi-node configuration a 64-core 128GB virtual machine on our SGI UV100 (check out /proc/cpuinfo and /proc/meminfo below :-), a cg1.4xlarge with Nvidia S2050 GPU attached (currently using the gVirtuS driver), and a Tilera TileEmpower TilePro 64-core (8x8) system.
We're going to start posting some of our results out on to the openstack wiki, but hopefully for Diablo, we will no longer need a homogeneous cloud infrastructure.
