Phoenix System of Stanford University (single-machine multicore mapreduce applications)

First, Introduction:

1, Phoenix is in the shared memory of the MapReduce implementation of the architecture. Its goal is to make programs execute more efficiently on multi-core platforms, and to keep programmers from having to care about concurrent management. In fact, concurrent management, though an experienced programmer, inevitably makes an error on this. 2. The Phoenix consists of a set of simple APIs open to application developers and an efficient runtime composition. runtime system handlers concurrency, resource management, and bug fixes, which are built on top of P-thread and, of course, easily ported to other shared memory line threading.

3, the website http://mapreduce.stanford.edu/can download to the newest program and the source code.

second, I use the platform:kubuntu-11.10-desktop-amd64

Third, note: The operating system must be 64 bits, need to compile with GNU make

Iv. Summary of issues

Problems encountered in Q1:make:

Undefined reference to ' sem_wait ' undefined reference to ' sem_post ' undefined
reference to ' Sem_destroy
' Undefined reference to ' sem_init '
