Hi,

If you are talking about types as ArrayList<Double>, it is not possible, because the Double (D uppercase) is an object which encapsulates a double. And the elements of an ArrayList are references (pointers) to Java objects.

You can use complex types but you must create them with the Datatype methods (createVector, createStruct,...). And the buffers that hold the data must be arrays of a primitive type or direct buffers.

Regards,
Oscar

Hi,

Is it possible to use non-primitive types with MPI operations in OpenMPI's
Java binding? At the moment in the trunk I only see Datatypes for primitive
kinds.

Thank you,
Saliya
