am new to cluster computing, so please bear with me.
currently trying to utilize the available desktops found in labs.
Started trying out 2 labs, (namely Lab A which have 192.168.0.xx IPs
and Lab B which have public IPs 202.185.77.xx series)
Have been running Paraview in Lab A without any problem so far.
(mpirun -np 18 -machinefile quad_lan pvserver)
As i tried to extend the cluster to Lab B's desktops, by specifying their
my machinefile like:
18.104.22.168 slots=4 max-slots=4 *#(eth1 = 22.214.171.124; eth0 =
126.96.36.199 slots=2 max-slots=2 *<-- this is "pc226*"
192.168.0.227 slots=2 max-slots=2
my programs hangs while my client tries to connect to the pvserver.
if i wait long enough, it will show the error
yewyong_at_vrc1:~/installer/mpi_test> mpirun -np 8 -machinefile quad_hama
Listen on port: 11111
Waiting for client...
connect() failed: Connection timed out (110)
note that when running "hello_world", it shows that the makeshift cluster
are able to communicate which each other.
after trying out different sequence in the machinefile, i found out that
whenever a cross IPs mpirun server is started, the system pauses
when the client tries to connect.
Would it be related to the problem raised in "
i'm not too sure if i've fully described the situation, please let me know
if you guys need any extra information.
thank you in advance.
