The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

In this post I'll introduce some new things I've developed for WSS estimation: two Linux tools, and WSS profile charts. Short durations can be useful for understanding how well a WSS will fit into the CPU caches (L1/L2/L3, TLB L1/L2, etc). But we don't know how much of that is in heavy use, which is what WSS tells us. 16.570 403.66

Our straining database infrastructure on Oracle led us to evaluate if we could develop a purpose-built database that would support our business needs for the long term. Performant – DynamoDB consistently delivers single-digit millisecond latencies even as your traffic volume increases.
