For the symmetric matrix-vector multiply, the calling sequences are given by place HR here

Parameter `UPLO` has been replaced by
integers `uplo`, which can take on
the values indicated in Table .
All other parameters are now passed as part of linear algebra
objects `alpha`, `a`, `x`, `beta`, and `y`.

When a node calls `PLA_Local_symv`, the operation
is equivalent to
extracting the local information (datatype, dimensions, and pointer to the
buffer) and locally performing the symmetric matrix-vector multiply.
Thus, the *local* matrix must be square, symmetric, and stored
in the indicated portion of the local buffer.
The local dimensions of `alpha` and `beta` must be ,
but they can be of any object type.
The local dimensions of `a`, `x`, and `y` must be such
that the operation is well-defined. All objects must have the same datatype.
Notice: no communication is performed as part of this call.
Thus, all information must be locally available.

All nodes must simultaneously call `PLA_Symv`, which performs
the BLAS call on the distributed objects.
Parameter `uplo` now indicates if the global matrix *A* is
stored in the upper or lower triangular portion of object `a`.
Parameters `alpha` and `beta` must now
be multiscalars. Parameter `a` must be of object type
matrix. Parameters `x` and `y`
must both be of a vector object type, including vector, projected
vector, or duplicated projected vector.
The global dimensions of the different objects must be such
that the operation is well-defined.
