-====== Not enough memory to solve my problem with OSL ====== 
- 
-//GAMS/OSL complains that there is not enough memory to solve my problem. What do I do ?//  
- 
-The solver reports its memory estimate and availability in both the 
-listing file and the log as follows: ​ 
- 
-     Work space requested by solver ​  ​--- ​ 23.45 MB 
-     Work space allocated ​            ​--- ​  0.00 MB 
-     ​Maximum work space available ​    ​--- ​ 16.31 MB 
- 
-This indicates that GAMS/OSL estimated that 23.45 MB would be 
-required to solve the problem, and since only 16.31 MB were 
-available on the machine, no memory was estimated, and OSL did not 
-attempt to solve the problem. ​ 
- 
-Since 23.45 MB is a conservative estimate, the user could force OSL 
-to try and solve the problem with the memory available. This is done 
-by adding the following line,  
- 
-     ​mymodel.workspace = 16 ; 
- 
-where mymodel is the name of the model as specified by the model 
-statement. This should appear between the model and solve 
-statements. ​ 
- 
-If this causes OSL to crash, then the only option is to run the model 
-on a machine with more memory.
