Suite of nonlinear solvers

Edit Package sundials
https://computing.llnl.gov/projects/sundials

SUNDIALS is a SUite of Non-linear DIfferential/ALgebraic equation Solvers
for use in writing mathematical software.

SUNDIALS was implemented with the goal of providing robust time integrators
and nonlinear solvers that can easily be incorporated into existing simulation
codes. The primary design goals were to require minimal information from the
user, allow users to easily supply their own data structures underneath the
solvers, and allow for easy incorporation of user-supplied linear solvers and
preconditioners.

Atri Bhattacharya's avatar Atri Bhattacharya (badshah400) accepted request 1147937 from Nicolas Morey's avatar Nicolas Morey (NMorey) (revision 35) 
- Load the full mpivars instead of manually setting LD_LIBRARY_PATH
- Add flags to handle oversubscription for %check (bsc#1201273).
  _constraints avoids this in OBS, but local runs may not have 4
  cores available.

This source needs some overhaul. Sources are at https://github.com/LLNL/sundials now and 6.2.0 is the latest upstream release

6.2.0 is a major update, we may want to check if it does not break dependencies down the line. In the meanwhile, I have version 5.8.0 brewing in my home branch (but if 6.2.0 does not create breakages we should push it).

The failure with mvapich2 flavour may be independent of this nonetheless, so we may want to check what is up with that (I am testing this locally), or disable this flavour entirely.

From what I've seen, the failure (abort() being called within snprintf()) is coming from the mvapich2 package and not from sundials. Disabling the mvapich2 flavour is certainly a reasonable short-term fix.

@kwk makes sense to me. I have also checked that octave 7.1.0 (seems like the only major dependency) is compatible with sundials 6.x, so if you would consider re-submitting your update after disabling the mvapich2 flavour, I would be very grateful.

Thanks.

I fixed the potential buffer overflows in science:HPC/mvapich2 and re-added the mvapich2 flavour.
