Abstract:
1. A method for solving linear equations, wherein the method is implemented in a computer system configured for one of: (i) single precision calculation; and (ii) double precision calculation, wherein the computer system includes at least a random access memory and a disk storage device, the method comprising the steps of: applying an out-of-core linear solver process to a set of data, wherein at least one computation associated with the application of the linear solver process to the set of data generates at least one interim result; compressing, using a compression algorithm, the interim result associated with the linear solver process; storing the compressed interim result to the disk storage device; retrieving the stored compressed interim result from the disk storage device; decompressing the retrieved compressed interim result; and using the decompressed interim result in at least one further computation associated with the liner solver process; wherein the interim result is expressed in the form of at least: (i) an exponent e; and (ii) a significant value s; and wherein the compression algorithm comprises:
