### AI overview

The communiqué announces changes to ePouta flavors, including public availability of the gpu.2.1gpu flavor with an NVIDIA Tesla V100 and NUMA-aware CPU and memory behavior. It also announces the deprecation of hpc.*.westmere flavors and recommends replacement flavors for new instances.

### Source excerpt

We are making some changes to our flavor offering . Here's a summary of the changes: We now have even more GPUs in ePouta. The gpu.2.1gpu flavor is now publicly available and each has one NVIDIA Tesla V100 via PCI pass through. This flavor was already added in July but could only be accessed after requesting it from servicedesk. Now we are making them publicly available. The gpu.2.1gpu flavor is our first NUMA aware flavor. This should speed up CPU & memory heavy applications. Our current version (Newton) of OpenStack is not able to guarantee PCI devices from the same NUMA node too, this is possible to come when we get to Pike or later. Deprecation of hpc.*.westmere flavors This does not affect running instances but in the future you might see changes in the performance and therefor we suggest that you resize your flavor to a newer flavor type. You won't be able to launch new instances with the deprecated flavors. Flavors that will be deprecated and suggested replacement: hpc.medium.westmere - standard.xlarge hpc.large.westmere - hpc.4.10core hpc.xlarge.westmere - hpc.4.10core or hpc.4.20core hpc.largemem.westmere - hpc.4.20core or hpc.3.28core More information about the different flavors can be found here: https://research.csc.fi/pouta-flavours No known Copyright Please acknowledge 'Sir George Grey Special Collections, Auckland Libraries, 1-W682' when re-using this image.
