Hi,<br> I'm sorry if I'm asking too many times.<br> My case will need using mpi_init, so I install the MPICH2-1.4.<br> I'm using WindosXP, Cygwin, g95 and single-node systems.<br> And thank you, <span>Jayesh Krishna. Answering my questions to let me know I </span>should install latest Cygwin version.<br>
<br> So, I installed the latest Cygwin version on another computer.<br> And then the Cygwin <span lang="en"><span>Information</span></span> was CYGWIN_NT-5.1 PC03 1.7.16(0.262/5/3) 2012-07-20 22:55 i686 Cygwin.<br> Now, I can use mpiexec running cpi. And I can use -n <number> equal or greater than 4.<br>
<br> daizy@PC03 /cygdrive/c/cygwin/mpich2-1.4<br> $ mpiexec -n 4 ./examples/cpi<br> Process 0 of 4 is on PC03<br>
pi is approximately 3.1415926544231239, Error is 0.0000000008333307<br> wall clock time = 0.000000<br> Process 1 of 4 is on PC03<br> Process 2 of 4 is on PC03<br> Process 3 of 4 is on PC03<br> <br> daizy@PC03 /cygdrive/c/cygwin/mpich2-1.4<br>
$ mpiexec -n 5 ./examples/cpi<br> Process 0 of 5 is on PC03<br>
pi is approximately 3.1415926544231230, Error is 0.0000000008333298<br> wall clock time = 0.000000<br> Process 1 of 5 is on PC03<br> Process 2 of 5 is on PC03<br> Process 3 of 5 is on PC03<br>
Process 4 of 5 is on PC03<br> <br> I would appreciate if someone can help me with the following problem:<br> When I use command make testing in mpich2-1.4/test file, I still got error messages (detail saves in testing.txt).<br>
