用于模型交换的大型模型和 FMU
Large-scale models and FMU for model exchange
我想将大型模型从 Openmodelica 导出到 FMU 进行模型交换。
作为第一步，我使用此模型进行测试：
model BigModel "Tank-Pipe-Tank cloned n times"
//
constant Real g=9.8;
//
parameter Integer n = 1;
parameter Real A_a = 1;
parameter Real A_b = 1;
parameter Real c = 0.2 "Kinematic viscosity";
parameter Real rho = 1000.0;
//
Real P_a[n];
Real P_b[n];
Real H_a[n] (start=fill(2,n),each fixed=true);
Real H_b[n] (start=fill(1,n),each fixed=true);
Real F[n] "Flow";
equation
for i in 1:n loop
P_a[i] = rho * g * H_a[i];
P_b[i] = rho * g * H_b[i];
F[i] = c * (H_a[i] - H_b[i]);
A_a * der(H_a[i]) = -F[i];
A_b * der(H_b[i]) = F[i];
end for;
end BigModel;
改变"n"我们可以生成大模型。
根据OpenModelica版本和OS，最大方程数变化很大：
- Windows 10 64 位 - OM 32 位 - 16 GB RAM - 4 CPU - i7) => n = 2600;方程式 = 13000。
- Windows 10 64 位 - OM 64 位 - 8 GB RAM - i5 => n = 100；
方程式 = 500.
- Windows 10 64 位 - OM 64 位 - 16 GB RAM - 4 CPU - i7) => n =
与上一个类似。
- Ubuntu 17.10.1 64 位 - OM 64 位 - 虚拟机 - 8GB RAM - 1
CPU=> n = 22500;方程式 = 112500
这对你有什么意义吗？
是否有可能在 Windows 中达到 n = 22500？
谢谢！！！
这里的问题不是OMC，是GCC。
在 Windows 中，64 位 OMC 最大消耗 4.1G，n=22500 并生成文件。
然后 GCC 运行s 处理文件并耗尽内存。还可以使用 -n=1 来避免 运行 GCC 并行，因为这会消耗更多内存。
我运行这个脚本：fmu.mos
loadFile("BigModel.mo"); getErrorString();
translateModelFMU(BigModel); getErrorString();
使用命令行：
adrpo33@ida-0030 MINGW64 /c/home/adrpo33/dev/OMTesting/test
$ time ~/dev/OpenModelica/build/bin/omc -n=1 -d=execstat fmu.mos > trace.txt 2>&1
结果如下：
true

在 Linux 中我们使用 CLANG，在 Windows 中我们使用 GCC，看起来 GCC 更需要内存。
应该有可能达到 n=22500，但可能使用更新的 GCC，因为我们在 OMC 中的那个似乎崩溃了：
adrpo33@ida-0030 MINGW64 /c/home/adrpo33/dev/OMTesting/test/BigModel.fmutmp/sources
$ make SIM_OR_DYNLOAD_OPT_LEVEL=-O0
gcc -O0 -falign-functions -msse2 -mfpmath=sse -Iinclude/ -Iinclude/fmi2 -I. -DOMC_MODEL_PREFIX=BigModel -DOMC_NUM_MIXED_SYSTEMS=0 -DOMC_NUM_LINEAR_SYSTEMS=0 -DOMC_NUM_NONLINEAR_SYSTEMS=0 -DOMC_NDELAY_EXPRESSIONS=0 -DOMC_NVAR_STRING=0 -c -o BigModel.o BigModel.c
BigModel.c: In function 'BigModel_eqFunction_228127':
BigModel.c:847581:1: internal compiler error: Segmentation fault
我想将大型模型从 Openmodelica 导出到 FMU 进行模型交换。
作为第一步，我使用此模型进行测试：
model BigModel "Tank-Pipe-Tank cloned n times"
//
constant Real g=9.8;
//
parameter Integer n = 1;
parameter Real A_a = 1;
parameter Real A_b = 1;
parameter Real c = 0.2 "Kinematic viscosity";
parameter Real rho = 1000.0;
//
Real P_a[n];
Real P_b[n];
Real H_a[n] (start=fill(2,n),each fixed=true);
Real H_b[n] (start=fill(1,n),each fixed=true);
Real F[n] "Flow";
equation
for i in 1:n loop
P_a[i] = rho * g * H_a[i];
P_b[i] = rho * g * H_b[i];
F[i] = c * (H_a[i] - H_b[i]);
A_a * der(H_a[i]) = -F[i];
A_b * der(H_b[i]) = F[i];
end for;
end BigModel;
改变"n"我们可以生成大模型。
根据OpenModelica版本和OS，最大方程数变化很大：
- Windows 10 64 位 - OM 32 位 - 16 GB RAM - 4 CPU - i7) => n = 2600;方程式 = 13000。
- Windows 10 64 位 - OM 64 位 - 8 GB RAM - i5 => n = 100； 方程式 = 500.
- Windows 10 64 位 - OM 64 位 - 16 GB RAM - 4 CPU - i7) => n = 与上一个类似。
- Ubuntu 17.10.1 64 位 - OM 64 位 - 虚拟机 - 8GB RAM - 1 CPU=> n = 22500;方程式 = 112500
这对你有什么意义吗？
是否有可能在 Windows 中达到 n = 22500？
谢谢！！！
这里的问题不是OMC，是GCC。 在 Windows 中，64 位 OMC 最大消耗 4.1G，n=22500 并生成文件。 然后 GCC 运行s 处理文件并耗尽内存。还可以使用 -n=1 来避免 运行 GCC 并行，因为这会消耗更多内存。
我运行这个脚本：fmu.mos
loadFile("BigModel.mo"); getErrorString();
translateModelFMU(BigModel); getErrorString();
使用命令行：
adrpo33@ida-0030 MINGW64 /c/home/adrpo33/dev/OMTesting/test
$ time ~/dev/OpenModelica/build/bin/omc -n=1 -d=execstat fmu.mos > trace.txt 2>&1
结果如下：

应该有可能达到 n=22500，但可能使用更新的 GCC，因为我们在 OMC 中的那个似乎崩溃了：
