Minutes 20 November 2006
Present: Jagir, Karl, Shane, Peter.
AIX
- Shane built PETSc on hpc.
- MPI headers on AIX seem different to mpich so some tweaks were required in libMesh build.
- Parallel environment doesn't seem to be working at the moment: seems to need rsh.
CellML
- Integrator
- cvodes (from Sundials) maintains a lot of state information.
- Expensive in memory
- Not sure how well swapping the history information in and out of a single solver will work.
- How complex an integrator do we need?
- Complex integrators work well on single cell models but if we need a small time step for diffusion, is there any point in having a complex integrator?
- Start with integrators that don't need their own history information.
- cvodes (from Sundials) maintains a lot of state information.
Material base vectors from angles
- Karl has written some code for calculating these but it is not working yet.
