How to use a lot of threads ....

The SPARC M5-32 has 1,536 virtual CPUs. There is a lot that you can do with that much resource and a bunch of us sat down to write a white paper discussing the options(revised link).

There are a couple of key observations in there. First of all it is quite likely that such a large system will not end up running a single instance of a single application. Therefore it is useful to understand the various options for virtualising the system. The second observation is that there are a number of details to take care of when writing an application that is expected to scale to large numbers of threads.

Anyhow, I hope you find it a useful read.
