# [WM_PRECISION_OPTION] - Floating-point precision:# = DP | SP | SPDPexportWM_PRECISION_OPTION=DP 其中DP对应Double Precision,SP对应Single Precision,SPDP对应Mixed Precision。需要注意:若想使用混合精度,需要对修改环境变量编译两个版本。并按如下方式执行(举例snappyHexMesh仍然使用双精度,simpleFoam求解使用混...
./configure --enable-type-prefix--prefix=/usr/local/fftw --with-gcc --disable-fortran --enable-i386-hacks 其中,--enable-type-prefix 参数是为了同时使用single precision(单精度)和double precision(双精度),如果不使用它,最后只有以rfftw开头的文件被安装(real fftw); --prefix= 参数是设定安装目...
WM_PRECISION_OPTION=SP Note that single precision is required. Double precision is untested. The build process will produce the following 2 new OpenFOAM libraries: $(WM_PROJECT_DIR)/platforms/<platform>/lib/cuda/[lib]gpu.[so|dll] $(WM_PROJECT_DIR)/platforms/<platform>/lib/gpuless/[lib]gp...

Consider a case with moderately sized mesh consisting of \(N_p=10^6\) control volumes and \(N=1000\) snapshots of velocity and pressure have been saved with double precision. Constructing the corresponding data matrix requires approximately 30GB of memory. Computing the economy SVD requires at ...
