Memory Management

Memory management deals with disk and memory based treatment of different intermediates and integrals and determined by the variable incorelevel.

The memory can specified by the keyword maxcore

%cc

maxcore 100

end

The above input allocated 100 MB for the calculation. The default value of maxcore is 0.

The incore level is automatically selected by the program considering the size of different intermidate and integrals. The incorelevel 5 means all the quantities are kept on memory. Incorelevel 4 put the 4 external integrals on disk. The incorelevel 3 puts both 3 and 4 external integrals on the disk and is the default.

One can overwrite the automatically selected incorelevel by the keyword incore in the %cc block
