Hello, <\/p>\n

 <\/p>\n

I have a complex model in AIM looking to be solved, and I’m having issues with the out-of-core performance. <\/p>\n

 <\/p>\n

Can you kindly let me know which command (and which part to enter it) is used to run the “Distributed Sparse Matrix Solver” in “in-core” mode? <\/p>\n

 The Distributed Sparse Matrix Solver is currently running in the        
 out-of-core memory mode.  This memory mode may provide significantly    
 worse performance compared to the in-core memory mode, depending on     
 the amount of available system memory and I\/O speed.  Please monitor    
 the solver performance to ensure that the large amount of I\/O to the    
 solver files does not create a bottleneck for performance.               <\/p>\n

 *** ERROR ***                           CP =     333.172   TIME= 18:23:17
 An input\/output error has occurred while trying to open a file with     
 length = 33 GB.  Error code = 112, which translates to: There is not    
 enough space on the disk.

 The program is unable to open file file1.DSPtri.  If the suggestions in 
 the associated error messages immediately preceding and\/or following    
 this error message do not help resolve the file issue, please send the  
 data leading to this operation to your technical support provider,      
 along with the I\/O error code of -1 and the system error code of 0,     
 for help in determining the possible reasons as to why this file could  
 not be opened.                                                           <\/p>\n

 *** ERROR ***                           CP =     333.172   TIME= 18:23:17
