Hi,

I have installed INTEL parallel studio XE cluster edition on our 10 Node cluster machine. I'm able to compile using mpiicc but when i try to run my code using mpirun i'm getting error like this

"error while loading shared libraries: /app/intelMPI//impi/4.1.3.048/intel64/lib/libmpi_dbg.so.4: cannot restore segment prot after reloc: Permission denied"

I have checked my environment varibles path in .bashrc file, i've properly declared the LD_LIBRARY_PATH in .bashrc file. i dont know exactly what is happening.

Hi Srinivasan,

Hi Srinivasan,

Could you please check SELinux status on your system? If it's enabled try to disable it or configure SELinux to allow libmpi_dbg.so.4 execution.

Thanks artem,

Thanks artem,

SELINUX was enabled. I disabled selinux, its now working.
