This usually means that u donot have a common filesystem on all of the machines in your machines list; MPICH requires this for mpirun (it is possible to handle this in a procgroup file; see the¡K¡K) Other possible problems include:- The remote shell command rsh doesnot allow you to run ls. See the doc abt remote shell & rhosts You have common filesystem, but with inconsistent names See the doc on the automounter fix 1 error were encountered while testing the machines list for LINUX only these machines seem to be available host1 now since this is only a two node cluster host1 is the server on to which MPICH is being installed. & 192.168.0.25 is the client¡K.. rsh on both nodes is logging freely¡K¡K. On the server side the file ¡§ machines.LINUX ¡§ contains -192.168.0.25 -host1 Kindly help Akhtar |
