Veselin Dobrev 9b73c3c47b In HypreParMatrixFromBlocks, use O(log(P)) binary search instead 
of O(P) linear search, where P is the number of processors.

Resolved conflict:

Veselin Dobrev 8798a933f3 Add support for 64bit HYPRE_Int in HypreParMatrixFromBlocks() and 
GatherBlockOffsetData().

Add overflow check in GatherBlockOffsetData().

In the SuperLURowLocMatrix constructor from HypreParMatrix,
remove the check for the number of columns and add a note why it is
not necessary at the moment.

Add a compile-time check when building with SuperLU_DIST support
that HYPRE_Int is int which is required by the current implementation.

Veselin Dobrev 50d95d0618 Various small fixes in SUNDIALS-related code. 2019-07-12 17:58:32 -07:00
Veselin Dobrev 6e457ec497 Fix a few issues related to using the classes SparseMatrix, 
HypreParVector, HypreParMatrix, and HypreSmoother with GPU backends.

Add 2 versions of a new method: Vector::MakeRef -- one that takes
a Vector and an offset and another that takes a Vector, an offset
and a new size.

Add some simple debugging tools:
 * Add a new output "trace" stream: mfem::trc. By default, the output
   of mfem::trc goes to std::cout; the new function mfem::OpenTraceFile()
   can be used to redirect the output of mfem::trc to a file called
   'mfem-trace-<pid>' where <pid> is the process id. Note that this
   function can be called from a debugger.
 * In class Vector, add a new method Vector::PrintTrace() that prints a
   Vector to the mfem::trc stream -- this method can be called from a
   debugger, unlike Vector::Print with mfem::trc as argument (at least
   in gdb this did not work).
 * In class Memory<T>, add 2 new methods: PrintFlags() and
   CompareHostAndDevice() which are explicitly instantiated for T=int
   and T=double, so that they can be called inside a debugger for
   these two types.

Veselin Dobrev 994fd13162 Ensure the method HypreParMatrix::Mult(HypreParVector &, 
HypreParVector &, double, double) can be used when the mfem::Device is
configured with a backend using a separate memory space, e.g. "cuda".
