This article is related to ADDA (light scattering simulator based on the discrete dipole approximation).

I am writing a tool to read Chpoint file based on the code written in SaveIterChpoint() of iterative.c.
https://github.com/adda-team/adda/blob/master/src/iterative.c

In the writing code, scalars[i].size and vectors[i].size are used to write scalars[i] and vectors[i] in the file as follows:

iterative.c

static void SaveIterChpoint(void)
{
    ...
    // write specific scalars
    for (i=0;i<params[ind_m].sc_N;i++) fwrite(scalars[i].ptr,scalars[i].size,1,chp_file);
    ...
    for (i=0;i<params[ind_m].vec_N;i++) if (fwrite(vectors[i].ptr,vectors[i].size,local_nRows,chp_file)!=local_nRows)
    ...

The problem in reading the Chpoint file is that both the scalars[i].size and vectors[i].size ARE NOT written in the file.

Therefore I have to come up with some idea to obtain the values of scalars[i].size and vectors[i].size from somewhere else in order to read the Chpoint file.

(Update: Dec. 02, 2016)

At least, following values need to be written as auxiliary information to read the Chpoint file:

params[ind_m].sc_N
scalars[i].size
params[ind_m].vec_N
vectors[i].size
