In many otbcli processes (e.g. otbcli_DimensionalityReduction ) I get messages such as:
Estimated memory for full processing: 4473.96MB (avail.: 128 MB), optimal image partitioning: 35 blocks
I understand I can modify the 128 MB with the -ram option, but where does this 128 MB come from? Is it fixed or is it somehow calculated using information on the current free resources of the machine?
