ILOG CPLEX parallel optimizers take advantage of multiple processors to solve difficult optimization problems. With the proliferation of multi-core CPU machines, parallel computing is no longer exclusive to high-end users. The easily accessible ILOG CPLEX parallel optimizers make parallel optimization an option for a broad range of applications and can substantially reduce the time for solving large linear and difficult mixed integer programs.

Speedier solutions, increased throughput
ILOG CPLEX parallel optimizers provide a number of different options for leveraging the power of multiple processors. The ILOG CPLEX Parallel Barrier Optimizer achieves significant speedups over its serial counterpart on a wide variety of classes of linear programming problems. The ILOG CPLEX Parallel Mixed Integer Program (MIP) Optimizer exploits parallelism while solving nodes of the branch-and-cut tree for mixed integer programming problems. The Parallel MIP Optimizer implements a deterministic mode of operation that produces a repeatable, invariant solution path, as well as an opportunistic mode that takes full advantage of parallelism for potentially even better performance

In an alternative use of multiple processors, ILOG CPLEX Concurrent Optimizer can apply multiple algorithms to a single linear programming problem. Each algorithm operates on a different CPU in a race to find the best approach. This technique results in the fastest solution time, without having to predetermine the best algorithm.

ILOG Parallel CPLEX is available on all platforms supported by ILOG CPLEX.
