1.话说scalapck还是可以运行在异构平台上的，虽然效率目前未知，但是设计时有考虑这个异构的问题，证据如下
http://netlib.org/scalapack/scalapack_install.pdf 其中的2.4 Run the PBLAS Test Suite
Testing instructions with MPICH on a network of workstations
Then, to run the executable, you will use the command mpirun. For example,
      mpirun -np <number of processes> <executable>
    where <executable> is replaced by xspblas1tst, and so on. If the network of work-
stations is heterogeneous, you will need to specify the -p4pg option and supply a text file
containing the names of the machines and the locations of the executables to which you will
spawn tasks. Refer to the mpirun manpage for complete details. read more
