5. An article of manufacture for executing on a parallel computer system with a plurality of compute nodes comprising: a query optimizer that creates an optimized query from a query to reduce network traffic over at least one of a plurality of independent networks connecting the plurality of compute nodes to a single database on the parallel computer system, wherein the query optimizer creates the optimized query by splitting the query to use multiple independent networks of a plurality of independent networks to access the single database, wherein the query optimizer uses plan cache statistics from previously executed queries to determine whether to use the multiple independent networks to optimize the query; and non-transitory computer recordable media on which computer instructions are stored, which instructions, when read by a computer, cause the computer to perform the steps of the query optimizer; wherein the plan cache statistics comprises: query identification (ID), execution time, nodes involved, and estimated number of bytes for the query; and wherein the query optimizer uses a network file containing network file information for the multiple independent networks comprising: network ID, a timestamp; current utilization, availability, latency, and retransmits.
