你好，我有一台dell poweredge 2900 的工作站在用。双cpu，各4个核心。系统是linux es 4.5 ，内核elsmp.我发现这8个核很多情况下都不能完全利用，所以想安装mpich2。
请问：
1  像我这种情况应该是否可以安装？
2  如果可以，这种情况是一个节点，所以在.mpi.conf中应该就指定一个主机吧。我就写了“localhost.localdomain”。利用的时候mpiexec应该指定8个线程就可以了吧。不知道对不对。
3  我安装完以后，mpdroot -n 1 -f ./mpd.hosts.报mpdroot: open failed for root's mpd conf file错误。
各位大虾能否指点一下？非常谢谢

对不起,是在 .mpi.host中指定主机。

没有人啊。。。。
在MPICH的网站上查询，有人问这个问题，但是回答好抽象阿。

Q: Can MPI be used to program multicore systems?
A: There are two common ways to use MPI with multicore processors or multiprocessor nodes:

Use one MPI process per core (here, a core is defined as a program counter and some set of arithmetic, logic, and load/store units).
Use one MPI process per node (here, a node is defined as a collection of cores that share a single address space). Use threads or compiler-provided parallelism to exploit the multiple cores. OpenMP may be used with MPI; the loop-level parallelism of OpenMP may be used with any implementation of MPI (you do not need an MPI that supports MPI_THREAD_MULTIPLE when threads are used only for computational tasks). This is sometimes called the hybrid programming model.
