1. MCSTL: The Multi-Core Standard Template Library Xiaofan Liu 29.01.2008

2. Introduction STL : Standard Template Library MCSTL:  Shared memory systems  Small inputs  Dynamic load balancing  The level of parallelism

3. Algorithms

4. Embarrassingly parallel Find Partition Sort

5. Algorithms Embarrassingly Parallel:  “Work stealing”  A user-tunable granularity

6. Algorithms Find:  m: the first matching element’s position  Size of blocks  m 0 m M

7. Algorithms Partition:  a blocked strategy  O(n/p+p) ‏ Sort:  Multiway Mergesort:  Load-Balanced Quicksort :

8. Software Engineering OpenMP 2.5 Using the MCSTL in a program Website: http://algo2.iti.uni-karlsruhe.de/singler/mcstl/

9. Experimental Result

11. Conclusion Already done Future work:  Implementation of worthwhile functions  Add dynamic load balancing to more functions  Configure it with right tuning parameters  Integrate it with the external memory library STXXL
