Diversity and ecosystem stability
• Shannon Weaver index of biodiversity
• In general, ecosystem stability goes up as biodiversity goes up
• Of course, human affairs are different, since recent years have shown us that economies and efficiencies of scale and the wisdom of markets make all this sort of thinking out of date as regards human activities
• ….or maybe not so much
If you think of supercomputing centers as an ecosystem• It seems clear that supercomputer center
diversity is currently going down over time• The biggest centers (at least as viewed from the
outside) seem to be doing reasonably well• Smaller centers (newer centers, or smaller
centers at colleges) are cropping up and sometimes doing very well
• The segment of the community that seems to be struggling most is the state-level center
• Our supercomputer ecosystem is not as diverse and therefore not as stable as it once was and we should as a community work to restore diversity
We should mind the lesson of Irish Elk

In supercomputing, ephemeral salary resources….
• Transform scientific programmers to generic commercial programmers, and talent is lost to the HPC community – often permanently
• And decrease attractiveness of scientific computing as a career (what Thanksgiving?)

Recommendations• Supercomputer centers
- Need to diversify more and think of ourselves as more than just supercomputer centers (PTI is trying to do that)
- Constantly make the case to our campuses and states- Constantly work with our tech transfer organizations to create real
economic benefit- Find ways to add distinctive value in era of cloud computing
• Campuses and States- Must continue investing in their local centers
• Funding agencies- Should pursue strategies in funding that provide longer term reliable
financial resources- Fund more kinds of centers than supercomputer centers
• Everyone- Needs to recognize that the US needs a balanced and diverse
ecosystem of supercomputer and related centers and doing this requires better long-term support for the people who enable these centers to function
