cfx考虑调整“enforce system memory limit”参数的设置

Question

cfx报错code001，提示系统内存不足，我的总网格数是七千多万，设置4个核，本机物理内存是1T，RAM32G，处理器12th Gen Intel(R) Core(TM) i5-12400F 2.50 GHz，AYSYS是2022R1版本，因子都是设置1.2，因子越大， Allocated就越大，陷入死循环。求该怎么设置呢？

Host         | Npart |   System    |  Allocated  |   %   |

                     4  |    32605.73 |    97255.77 |298.28 |

ERROR #333100220 has occurred in subroutine Out_Memory.
Message:
The allocated memory exceeds the system memory on 1 host(s).
The logical expert parameter "enforce system memory limit"
controls whether this is a fatal error.
The current setting is: fatal

请参考以下代码示例来解决此问题：

#INCLUDE <IOSTREAM>
#INCLUDE <VECTOR>

USING NAMESPACE STD;

INT MAIN() {
    INT TOTALGRID = 7000000; // 总网格数（单位：百万）
    INT PHYSICALMEMORY = 1000000000; // 设置为1TB
    INT RAMSIZE = 32000000; // RAM大小（单位：GB）
    INT PROCESSORCORE = 12; // 利用处理器型号

    COUT << "TOTAL GRID: " << TOTALGRID << ENDL;
    COUT << "PHYSICAL MEMORY: " << PHYSICALMEMORY << ENDL;
    COUT << "RAM SIZE: " << RAMSIZE << ENDL;
    COUT << "PROCESSOR CORE: " << PROCESSORCORE << ENDL;

    IF (TOTALGRID > PHYSICALMEMORY / RAMSIZE) {
        COUT << "WARNING: THE TOTAL GRID EXCEEDS THE AVAILABLE PHYSICAL MEMORY." << ENDL;
    } ELSE {
        COUT << "OK: THE TOTAL GRID DOES NOT EXCEED THE AVAILABLE PHYSICAL MEMORY." << ENDL;
    }

    RETURN 0;
}
