Initializing help system before first use

# COMPUTE

Description | Controls whether the next solve is performed directly or on an Insight Compute Interface.
Type | Integer
Topic area | Compute Interface
Values |
0 | Solve locally.
1 | Solve using an Insight Compute Interface.
Default value | Depends on environment
Note | This control can only be used if Xpress is not in compute mode due to the environment variable of the same name XPRS_COMPUTE being set before initialising Xpress. The first time the control is set to 1, Xpress reads the XPRS_COMPUTE_URL environment variable for the server address. Once enabled, the same restrictions apply to any solves that normally applies to solves (e.g. a restricted set of callbacks are supported). Enabling compute mode this way does not release the license held by Xpress.
Affects routines | XPRSmipoptimize ( MIPOPTIMIZE), XPRSlpoptimize ( LPOPTIMIZE), XPRSiisfirst ( IIS), XPRSrepairinfeas ( REPAIRINFEAS).
