[Openstack] State of virtualised GPU use in instances?

I¹m interested in accelerated high throughput microscopy workloads involving
deconvolution using stream processors via CUDA interfaces to GPU¹s.

Last I checked, things were not going all that well in terms of GPU inside


I got the impression that the direction being pushed was that a more
cohesive or heterogenous use of SRIOV for all PCI based devices was being
considered instead, as opposed to just GPU.

Could someone give me a brief explanation as to where we sit with
virtualised GPU inside instances? For sake of argument, it could be a Xen or
a KVM guest. Whatever. Either way.

Thank you.
