I used WindosXP, Cygwin and g95 to install MPICH2-1.2.1p1 on my personal computer (Intel Core2 Quad Q8200).<br>

<br> I use mpirun -n 2 to run my case, and get some error messages<br> rank 1 in job 2 980622-05_3343 caused collective abort of all ranks<br> exit status of rank 1: killed by signal 9 <br> rank 0 in job 2 980622-05_3343 caused collective abort of all ranks<br>

Since you set both F77 and FC to the same compiler g95.<br>
Whatever compiler behavior changing flag you set for F77<br>
should be set for FC during configure as well, i.e. if<br>
you set FFLAGS=-fno-second-underscore, you should set<br>
FCFLAGS=-fno-second-underscore. If you do that, you don't<br>
need to use -fno-second-underscore with mpif90 in compiling<br>
your code.<br>
<br>
However, I don't get why would want to change the default<br>
name mangling behavior of the Fortran compiler. Based on<br>
the compiling output of your app, it appears your app is<br>
pure Fortran90 code. Would it be easier just not setting<br>
-fno-second-underscore at all in compiling mpich2 and your<br>
app ?<br>
