Slightly reduce memory allocation in GMRES

Jacques Xing requested to merge CFD-Xing/nektar:feature/reduce-memory-allocation-in-GMRES into master

Issue/feature addressed

A temporary Array of size nGlobal is used as a temporary storage before the final output is updated. This is unnecessary as an Array of size nNonDir is sufficient.

Proposed solution

Reduce the Array size of the variable solution from nGlobal to nNonDir and update code accordingly.

Implementation

Tests

Suggested reviewers
