Veselin Dobrev 6caa552f0d Fix SUNDIALS + CUDA support when using SUNDIALS < v6 2022-10-06 00:44:05 -07:00
Chris Vogl f36aa1aece corrected SUNLinSolSPFGMR wrapper to use SPFGMR instead of SPGMR 2022-09-21 13:47:40 -07:00
Cody J. Balos 0142bb7c81 Address undef. behavior from 'recursive' init of singleton 
According to the standard, recusrive initialization of a static
object is undefined. Some compilers handle it fine, but XL does not.

Also ensure that only one instance of Sundials class instantiated.

Aaron Fisher e758c37691 Removed nearly all leading underscores for variable names. Every once in a while one of these will confilct with standard libraries in an oddball compiler and it's best to just avoid this problem alltogether. 2021-05-10 16:06:51 -07:00

increase the default value.

Balos, Cody Joe c36d6ca2b1 sundials-gpu-dev: a couple minor fixes 2020-09-21 08:57:45 -07:00
Balos, Cody Joe a5bb313e52 Update to SUNDIALS 5.4.0 RC 
This has no changes to the CPU only code (all changes were in
MFEM_USE_CUDA ifdef). The primary change is that mfem controls the
lifetime of the SUNMemoryHelper, thus the SundialsMemHelper class and
mfem::sunmemHelper were added.

Balos, Cody Joe 937db1a293 Add support for SUNDIALS GPU features 
Add support for SUNDIALS CUDA features. These changes will be easily
extendable to support future GPU features in SUNDIALS, e.g. HIP
features. To keep things clean, this creates a SundialsNVector
class to interface with the SUNDIALS N_Vector. This class inherits
from the mfem::Vector class, and follows the pattern used in MFEM
interfaces to other libraries such as PETSc and hypre.
