<DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I got an strange error when I run my parallel program.</DIV>
<DIV> </DIV>
<DIV>job aborted:<BR>rank: node: exit code[: error message]<BR>0: abyss: -1073741819: process 0 exited without calling finalize<BR>1: abyss: -1073741819: process 1 exited without calling finalize<BR>2: abyss: -1073741819: process 2 exited without calling finalize</DIV>
<DIV> </DIV>
<DIV>My program works as expected under Linux. But when I porting it to windows I got above error. It is compiled by VC8 and Intel FORTRAN 10.0.</DIV>
<DIV>I didn't built my own MPICH2, but link my program with fmpich2s.lib and mpi.lib which were installed from mpich2-1.0.6p1-win32-ia32.msi.</DIV>
<DIV> </DIV>
<DIV>This error happened inside the call to MPI_SEND. Does anyone have an idea about this error?</DIV>
