When H5VL_LOG_NSUBFILES is 0, subfiling is disabled.
When H5VL_LOG_NSUBFILES is not set, subfiling is disabled.
WHen H5VL_LOG_NSUBFILES is negative, one subfile per compute node.
WHen H5VL_LOG_NSUBFILES is set without a value, one subfile per compute node.
The above applies to the argument nsubfiles of API
