Root directory description

.bin

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)

.doc

contains all documentation

.examples

examples using SPar annotations

.libraries

are the libraries used by SPar

For compiling a program with spar, please type:

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

SPar compilation flags

  • -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

Obs: you may use '-h' to see more options
