Dear all, I am new in Linux and clustering. I am setting up a Beowulf Cluster using several PCs according to this guide http://www.tldp.org/HOWTO/html_single/Beowulf-HOWTO/.
I have setup and configure accordingly except for NFS part. Because I am not requiring it for my application. I have set my ssh to login each other without password. I started with 2 nodes 1st. I can compile and run in my headnode using openmpi. But when I try to run my MPI application across nodes, there is nothing displaying. It just like hanging there. Headnode: master client: slave4 The command I used to mpirun across nodes is as below: Code:mpirun -np 4 --host slave4 outputSince I not using NFS, so I installed OpenMPI in every nodes with same locations. I wondering I missed out any configurations or not. Hope someone can help me out of this problem. Thanks in advance. Best Regards,Shi Wei
