Read C API: chunk_size via adios_read_init_method

[ax3l]

I would like to make the following proposal / RFE for an upcoming 1.9 release:

It would be great if one could set the option for the chunk_size during reads alternatively via the C API in adios_read_init_method (params, third argument).

Right now, the only way I know of is to export of a real environment variable.
If not set, both ADIOS_READ_METHOD_BP and ADIOS_READ_METHOD_BP_AGGREGATE complains about it and aborts execution.

yes I can confirm that, ADIOS_READ_METHOD_BP is not affected - I had some nfs issues this day and probably an old binary was tested.

Hi Axel,

This is a valid request, however, I don't think ADIOS_READ_METHOD_BP
requires any parameter. Can you double check that please?

The ADIOS_READ_METHOD_BP_AGGREGATE was very experimental, it was never
used by applications, hence the ad-hoc passing of arguments through
environment.

Best regards
