hello guys, this is 3rd thread related to same issue. but no one replied, now i am tring last chance to someone would help...
Actually i am design parallel computation using beowulf clustering concept, the software i am using 'mpich2'.i have 10 computer, for instance i trying for 2 computer, 1 mater(chipwarequantum) and other 2 node(node1). now i did whatever is available on net i tried those steps but its not working
but when i tried this it works
[santosh@chipwarequantum]$ mpirun -np 1 a.out
Process 0 of 1 on chipwarequantum
pi is approximately 3.1415926544231341, Error is 0.0000000008333410
wall clock time = 0.000618
[santosh@chipwarequantum]$ mpirun -np 2 a.out
p0_21125: (64.955735) Procgroup:
p0_21125: (64.955789) entry 0: chipwarequantum 0 0 /home/santosh/mpich-1.2.7p1/examples/basic/a.out santosh

p0_21125: p4_error: Could not gethostbyname for host chipwarequantum; may be invalid name
setting for this cluster
# Change this file to contain the machines that you want to use

# where n is the number of processors in an SMP. The hostname should
# be the same as the result from the command "hostname"

please anybody help me in i waiting for long daysssssss ,,...
