Installation and License Questions / Re: password required when runned in mpiexec

« on: July 23, 2012, 14:06 »

Yes i have managed to combine all the computer together without ssh password...
But when i run any script i have observed that only one server is in use .that server is the one which is on the first in the machine file

for example

if my machine file is

quantum.xxx.xx
vlsi1.xxx.xx
vlsi2.xxx.xx

quantum takes away all the 3 slave licenses including the master.

same thing if i place 'vlsi1' at the top

please say if i am making any mistake ..

when i try to run a script using

Code

mpiexec -n 2 -machinefile mymachinefile $ATK_BIN_DIR/atkpython script.py > script.log

it asks for password every time and of all the three other machines.

is there any way to disable the password .i am using a redhat cluster

It's very difficult to say, it seems like some network problem. The error message is not printed by ATK, but by ssh showing that it is having problems connecting to the slave nodes. Check that mpd and is properly set up, and make sure the "test_mpi.py" script finishes properly before moving on to running more complex scripts.

Yes when i type 'mpdtrace' or 'mpdboot' it gives as "command not found"

Doesnt MPD installs automatically with mpich2.

the installation procedure we got does not have any mention about mpd

it shows only to install mpich2

by unzipping in the usr folder

./configure

make

make install

and editing bash

When i changed the host name to the IP ( for example 10.0.0.4) the message stopped coming ..

now mpiexec run on 10.0.0.4 gives the following log file

When we use the command

Code

 mpiexec -n 4 /opt/QuantumWise/atk-12.2.0/atkpython/bin/atkpython /home/user/my_script.py > /home/user/my_script.log [code]

to submit a job (my_script.py) the simulation hangs after some time indicating that the slaves are not working.what might be the cause ?[/code]

Thanks it worked.. but next when i run the test script given in parallel guide

Code

mpiexec -n 4 /opt/QuantumWise/atk-12.2.0/atkpython/bin/atkpython /home/user/test_mpi.py > /home/user/test_mpi.log

it returns as

Code

 ssh:vlsi1: Temporary failure in name resolution [code] 

[/code]

the IP of the license server is 10.0.0.1

slaves are 10.0.0.2, 10.0.0.4, 10.0.0.5

ping 10.0.0.1 gives reply from all the 3 slaves

Hi i have connected 4 servers(1 is the master  where the license is installed)  using procedure given in the Parallel Guide tutorial.we have used mpich2.

now when we use the command mpdtrace , it gives "command not found" .

Also the command lmxendutil -licstat shows that there is no license server available..

Installation and License Questions / Re: what license i need to run a simulation in 4 servers

3 slaves is a perfect license to run in parallel on this setup.

someone told that 1 slave is needed for 1 core.

ie 4 servers*8 core=32 core =32 slaves

Installation and License Questions / what license i need to run a simulation in 4 servers

« on: June 5, 2012, 07:41 »

I am running ATK in a 8 core server ..now three other server has come to my lab all are 8 cores ie total of 32 cores...

my license are

[2011-12-19 16:43:10] atksemaster (v11.Cool (1 license(s)) license type: exclusive
[2011-12-19 16:43:10] atkseslave (v11.Cool (3 license(s)) license type: exclusive
[2011-12-19 16:43:10] vnl (v11.Cool (1 license(s)) license type: exclusive

Is it possible to use all the four servers to full potential. what is core based license and workstation based license

doesn't 3 slave license can accommodate 3 servers ..or other extra license is required..
