MATMPIAIJVIENNACL= "aijviennacl" = "mpiaijviennacl" - A matrix type to be used for sparse matrices. A matrix type (CSR format) whose data resides on GPUs.
All matrix calculations are performed using the ViennaCL library.
<P>
This matrix type is identical to <A HREF="../Mat/MATSEQAIJVIENNACL.html#MATSEQAIJVIENNACL">MATSEQAIJVIENNACL</A> when constructed with a single process communicator,
and MATMPIAIJVIENNACL otherwise. As a result, for single process communicators,
<A HREF="../Mat/MatSeqAIJSetPreallocation.html#MatSeqAIJSetPreallocation">MatSeqAIJSetPreallocation</A> is supported, and similarly <A HREF="../Mat/MatMPIAIJSetPreallocation.html#MatMPIAIJSetPreallocation">MatMPIAIJSetPreallocation</A> is supported
for communicators controlling multiple processes. It is recommended that you call both of
the above preallocation routines for simplicity.
