MEMCHECK

Indicates what should happen if chunking is detected

Description:

This parameter indicates what should happen if the available memory is too low to process the supplied time-series data without splitting it into chunks. It can take any of the following values:

0 - A warning is issued but makemap then continues to produce a map from the chunked data.

1 - An error is reported with status SMF__NOMEM and no map is created. The output map is created as normal if the available memory is sufficient to avoid chunking.

2 - An error is reported with status SMF__NOMEM and no map is created. In addition, an error is also reported with status SMF__MEMCHK and no output map is created if the available memory is sufficient to avoid chunking. Thus if memcheck is 2, no map is ever created. This is intended as a means to check whether chunking would or would not be used if makemap was to be used subsequently to create a map.

Note, in either case the SMF__NOMEM error is reported only if chunking is caused by lack of memory, not if it is caused by the supplied data being discontiguous. [0]
