–results_io_cache_size
Specifies the size of the results IO cache in kilobytes. When you run an analysis, the engine writes the results input and output file data first to the cache memory and then to disk. The value you specify here must be an exact power of 2. For example —2^9 (512), 2^10 (1024), 2^11 (2048). This number must be chosen judiciously, because a too high value could degrade the performance. Increase this value only if you have a very large model in which the number of equations exceeds 500,000.
The default value for this option is 1024 kilobytes of data.
