我在终端中使用了sudo apt-get install mpich。一切安装得很好。但是现在我必须根据these instructions编辑mgrid2的rc文件。我必须指定的一件事是安装mpich的路径，我找不到它！我确实在/ usr / include中找到了它的.h文件，但我确定这不是正确的路径。我已粘贴下面的安装输出。
有关如何找到mpich安装位置的任何想法？我正在运行Ubuntu 15.10。

修改 -
说明建议路径为/usr/x86-local/mpich/ch_p4，但我没有/usr/x86-local/仅usr/local而且它不存在。
find /usr -name mpich和whereis mpich已退回：
/usr/share/doc/mpich --copyright info and shortcuts stored here
/usr/include/mpich --.h files stored here
/usr/lib/mpich --shortcut to /usr/include/mpich only
which mpicc和whereis mpicc已退回：
/usr/bin/mpicc.mpich
/usr/bin/mpicc
/usr/bin/mpicc.mpich2
/usr/share/man/man1/mpicc.1.gz
重点是，当我执行ls时，到目前为止我没有尝试过任何子目录ch_p4。

您可以使用dpkg -L mpich或find /usr -name "mpich"查找mpich的安装路径。
此外，如果您特别想使用mpich编译或运行MPI程序，并确保您没有使用其他MPI库（如OpenMPI）。您可以通过将mpich的名称后缀到MPI命令（例如mpicc.mpich，mpicxx.mpich，mpirun.mpich等）来直接调用mpich
