class Qthreads(AutotoolsPackage):
"""The qthreads API is designed to make using large numbers of
threads convenient and easy, and to allow portable access to
threading constructs used in massively parallel shared memory
environments. The API maps well to both MTA-style threading and
PIM-style threading, and we provide an implementation of this
interface in both a standard SMP context as well as the SST
context. The qthreads API provides access to full/empty-bit
(FEB) semantics, where every word of memory can be marked
either full or empty, and a thread can wait for any word to
attain either state."""
