IBM Austin researchers have demonstrated a new method for building
a large scale server based on Non-Uniform Memory Access (NUMA) technology
with key differentiators. The advantage of this method is that a NUMA
server can be economically productized out of existing standard high
volume (SHV) components, cutting cost and time to market. The success
of this project has motivated several strategic decisions in Server
Group with long-term effects on IBM product plan and business. The
key technology differentiators include a non-intrusive performance
monitoring card that can be deployed in production systems; a scalable
lock architecture tuned for large-scale machines; and the RSet API
provides NUMA-aware applications with means to control resource allocation
for optimum performance. These differentiators are currently being
incorporated in several products from the server group.
