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.

Material base vectors from angles

• Karl has written some code for calculating these but it is not working yet.
