Implementation
Topology of I/O code
- I/O functions were initiated from cem_out function of cem_dg.F (and cem_dg2.F).
- Implementation of parallel I/O routine were defined in vtkbin.c and rbIO_nekcem.c
- vtkcommon.c and vtkcommon.h serve as a place to hold common functions as well as global variables.
NekCEM notes for myself
- .box → num elements in x,y,z
- .rea → input data
- SIZEu → SIZE parameters:
- lp = #proc
- lelx = 20 each dimension
- lelv = alloc max # of element per proc
- .usr rarr; subuser.F
- cem() in cem_dg.F is the main solver and application entry point
To-do List
- More tests on BG/P for config with ng = M and 1< nf < M
- Tests on Kraken and Jaguar
- Pthread + MPI for I/O
- OpenMP/Pthread + MPI for NekCEM computation
- Parallel I/O for reading .rea file
Some notes
- Fortran generated binary file may not be correctly read in C.
- -lstdc++ for link
- libF77 and libI77
- common.h and common_c.h
- write() in Fortran: 6 refer to screen, * is to screen as well ..
