contains the 'spar' compiler, which is responsible for recognizing SPar annotation and generate stream-based parallel code targeting multi-core systems with FastFlow library (which builds on top of Pthreads)

contains all documentation

examples using SPar annotations

are the libraries used by SPar

$ bin/spar -std=c++1y -spar_file <filename>.cpp -o <filename> 

• -spar_print => used to print in the screen the generated code

• -spar_ondemand [<queue_size>] => used to generate ondmand scheduler

• -spar_ordered => used to preserve the stream elements' ordered

• -spar_blocking => used to activate the blocking mode of FastFlow
