ACTS tools interoperable with GA

• linear algebra: ScaLAPACK

  • interfaces to included in GA to multiple Scalapack operations
  • example: to solve a linear system using LU factorization user calls
  • 
    call ga_lu_solve(g_a, g_b)
    instead of
    call pdgetrf(n,m, locA, p, q, dA, ind, info)
    call pdgetrs(trans, n, mb, locA, p, q, dA, dB, info)
    

• PDE solvers: PETSc

• computational steering: CUMULUSV
