Mathematica provides not only automatic parallelization capabilities, but also a full built-in symbolic language for specifying concurrent computation.
Concurrent Evaluation
ParallelSubmit submit expressions to be evaluated concurrently
WaitAll wait for all concurrent evaluations to finish
WaitNext wait for the next of a list of concurrent evaluations to finish
EvaluationObject symbolic representation of an expression submitted for evaluation
SetSharedVariable specify symbols with values to synchronize across subkernels
SetSharedFunction specify functions whose evaluations are to be synchronized
UnsetShared stop variables or functions being shared
CriticalSection synchronize concurrent access using lock variables
$KernelCount number of running kernels, degree of parallelism
$KernelID a unique positive integer value assigned to each parallel kernel
