$title  Solving a Transportation Problem using Gurobi remote server (RS01,SEQ=611)
$onText

We solve the trnsport model using the Gurobi remote server. The information about the compute server
addresses (using Gurobi's compute manager), ports and password come through the environment variable
GUROBI_CS_MANAGER, GUROBI_CS_USER and GUROBI_CS_PASSWORD.
