sasoptpy.actions.cofor_loop

cofor_loop(*args)

Creates a cofor-loop to be executed on the server concurrently

Parameters

argssasoptpy.abstract.Set objects

Any number of sasoptpy.abstract.Set objects can be specified

Returns

set_iteratorsasoptpy.abstract.SetIterator, sasoptpy.abstract.SetIteratorGroup

Set iterators to be used inside cofor-loop

Notes

A cofor-loop runs its content concurrently. For tasks that depend on each other, consider using sasoptpy.actions.for_loop()

Examples

>>> with so.Workspace('w') as w:
>>>     x = so.VariableGroup(6, name='x', lb=0)

>>>     a1 = so.Constraint(x[1] + x[2] + x[3] <= 4, name='a1')
>>>     for i in cofor_loop(so.exp_range(3, 6)):
