mpirun (v1.0.1) sets the umask to 0, and hence creates world-writable output files. Interestingly, adding the -d option to mpirun makes this problem go away. To reproduce:mpirun -np 1 --hostfile ./hostfile --mca pls_rsh_agent ssh ./a.out where a.out is compiled from: #include <sys/types.h> #include <sys/stat.h> #include <stdio.h> int main () { printf("%.4o\n", umask( 022 ) ); return 0; }
Wow, we definitely shouldn't be doing that. I've just committed a fix for this problem on the development branch of our subversion repository. The fix should be in the nightly builds in the next couple of days, and will be part of the upcoming 1.0.2 release.
