The question about the memory usage of Firefly

Hi, everyone.
A question about the memory usage of Firefly confuses me, recently.  
I did a calculations using Firefly 8.0 beta, attached please find the input file of this calculation. However, when I run it, the Firefly shows the information as follow:
----------------------------------------------------------------------------------------------
ADDING 30145072 WORDS MAY IMPROVE EFFICIENCY SIGNIFICANTLY!
***** ERROR: MEMORY REQUEST EXCEEDS MAXIMUM.
   45631552 WORDS REQUIRED     20000000 AVAILABLE.

                        TIMING STATISTICS ON NODE 0:
CPU        TIME:   STEP =      0.00 ,  TOTAL =     30.7 SECONDS (    0.5 MIN)
WALL CLOCK TIME:   STEP =      0.00 ,  TOTAL =     30.6 SECONDS (    0.5 MIN)
CPU UTILIZATION:   STEP =      0.00° TOTAL =     100.33SCP>    14848362 WORDS OF    DYNAMIC MEMORY USED
----------------------------------------------------------------------------------------------
The information of my computer is listed below:
----------------------------------------------------------------------------------------------
CPU: Intel Core 2 Quad 8400 2.33GHz, 4 Cores
Mem: 4 GB+4 GB Swap
System Info: Fedora 10 64 bit
HardDisk: 500 GB (more than 400 GB free space)
----------------------------------------------------------------------------------------------
I know the physical memory may not enough, but I still wanna finish this calculation without adding memory. I wonder whether the Firefly could run an expensive task by reducing the efficiency/speed. If possible, how to do it?
Thanks very much.
