ABSTRACT:
The solution program causes a computer to execute step1for performing, in parallel, the LU decomposition on the column block comprising a plurality of columns and for storing the result in the working area; step2for canceling the row permutation on the left of each column to the result in step1and for copying back the result in the array in compress mode; step3for saving the portion which may be damaged by updating the band matrix corresponding to the result in step1; step4for updating the band matrix in parallel by using the result in step1; and step5for returning the saved portion in step3to the result in step4.
