-Incremental Checkpoints
-.......................
-
-When the model-checker is configured to take a snapshot of each
-explored state (with the ``model-checker/visited`` item), the memory
-consumption can rapidly reach GiB ou Tib of memory. However, for many
-workloads, the memory does not change much between different snapshots
-and taking a complete copy of each snapshot is a waste of memory.
-
-The ``model-check/sparse-checkpoint`` option item can be set to
-**yes** to avoid making a complete copy of each snapshot. Instead,
-each snapshot will be decomposed in blocks which will be stored
-separately. If multiple snapshots share the same block (or if the
-same block is used in the same snapshot), the same copy of the block
-will be shared leading to a reduction of the memory footprint.
-
-For many applications, this option considerably reduces the memory
-consumption. In somes cases, the model-checker might be slightly
-slower because of the time taken to manage the metadata about the
-blocks. In other cases however, this snapshotting strategy will be
-much faster by reducing the cache consumption. When the memory
-consumption is important, by avoiding to hit the swap or reducing the
-swap usage, this option might be much faster than the basic
-snapshotting strategy.
-
-This option is currently disabled by default.
