armi.tests.test_mpiActions module

Tests for MPI actions.

class armi.tests.test_mpiActions.MockMpiComm

Bases: object

Mock MPI Communication library.

bcast(data, root=0)

Get_rank()

Get_size()

scatter(actions, root=0)

Split(num)

class armi.tests.test_mpiActions.MpiIterTests(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_parallel()

test_serialGather()

test_mpiIter()

test_perfectBalancing()

Test load balancing when numProcs divides numObjects.

In this case, all processes should get the same number of objects.

test_excessProcesses()

Test load balancing when numProcs exceeds numObjects.

In this case, some processes should receive a single object and the rest should receive no objects.

test_typicalBalancing()

Test load balancing for typical case (numProcs < numObjs).

In this case, the total imbalance should be 1 (except for the perfectly balanced case).

test_runActionsDistributionAction()

test_runActionsDistributeStateAction()

test_diagnosePickleErrorTestReactor()

Run _diagnosePickleError() on the test reactor.

We expect this to run all the way through the pickle diagnoser, because the test reactor should be easily picklable.

class armi.tests.test_mpiActions.QueueActionsTests(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_disableForExclusiveTasks()

test_makeQueue()
