Note that most C and C++ compilers look in /usr/include implicitly. Thus, mpicc should work automatically without the wrapper passing -I/usr/include. (Indeed, mpicc --showme shows no include arguments at all.) I'm not sure gfortran makes (or should make) the same assumption. Also note ...

On hybrid processors with efficient E-cores and performance P-cores, such as 12th and 13th Gen Intel® Core™ processors, Intel® MPI Library might pin processes to E-cores resulting in not best overall performance. We recommend disabling pinning with I_MPI_PIN=no, or using I_MPI_PIN_...
手动找寻则根据以下次序,通常mpi目录早已加入了环境变量,程序直接能找到mpicc,mpicxx以及mpif90三个编译器(可以直接在终端敲入这几个编译器,瞧瞧有没有输出,证明环境变量中有没有加入这几个编译器) 默认编译器的选择次序 指定安装目录: --prefix=/home/myname/petsc 指定是否debug: 指定不debug:--with-debugging=...
先确认使用which的账号，如果是非root账号的话，可能是没权限使用which的，可以切换到root或者在which命令前加上sudo。查找文件的话，还可以使用find命令，使用方法是：find /opt -name abc 这个命令是查找/opt目录下，名字带abc的文件 which
