- You may want to look at asynchronous iterative algorithms for finding fixed
- points. I have an implementation in which I solve a linear system of equations
- using such an algorithm on a network of workstations. You can get papers
- describing our system by anonymous ftp from cs.bu.edu.
- cd techreports
- mget *mermera*
- A paper describing the performance in detail is under preparation.
-
- The book "Parallel and Distributed Computation" by Bertsekas and Tsitsiklis
- gives an excellent description of these algorithms.
-
- I am not aware of Sahni's parallel all-pairs-shortest-paths algorithm. Could
- you please send me a reference.
-
- Thanks
