Hi, Recently I complied RELAX in our cluster [Linux 2.6.32-220.el6.x86_64 #1 SMP EST 2011 x86_64 x86_64 x86_64 GNU/Linux]. Whenever I submit a job directly or through "qsub" or "qsub -I" > mpiexec I am getting an error: "error initializing input projection driver. exiting" I am unable to get what could be the reason. Kindly help me out. regards - Anil
