More Threads, More Trouble?

My Google Alert on Erlang spew out this article: More Threads, More Trouble?

It starts with the observation that we move from increasing CPU clock speed to an increasing number of cores and then continues with a brief overview of prominent approaches to add concurrency to software systems / concurrent computing:

• time-sharing
• multi-processing / multi-tasking
  
• multi-threading
• shared memory
• OpenMP / MPI
• futures
• message passing (with Occam and Erlang mentioned)
• Communicating Sequential Processes (CSP)
  
• transactional memory / software transactional memory (STM)

For me it was a chance to collect some Wikipedia links for further reading.
