Function Documentation

SCIPconstructSyncstore()

SCIP_RETCODE SCIPconstructSyncstore

(

SCIP *

scip

)

Constructs the parallel interface to execute processes concurrently.

Returns

SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.

Precondition

This method can be called if scip is in one of the following stages:

• SCIP_STAGE_PROBLEM
• SCIP_STAGE_TRANSFORMING
• SCIP_STAGE_TRANSFORMED
• SCIP_STAGE_INITPRESOLVE
• SCIP_STAGE_PRESOLVING
• SCIP_STAGE_EXITPRESOLVE
• SCIP_STAGE_PRESOLVED
• SCIP_STAGE_INITSOLVE
• SCIP_STAGE_SOLVING
• SCIP_STAGE_SOLVED
• SCIP_STAGE_EXITSOLVE
• SCIP_STAGE_FREETRANS

See SCIP_STAGE for a complete list of all possible solving stages.
