General Questions and Answers / Running QATK on Multiple Nodes
« on: July 19, 2022, 19:44 »
Dear Admin, I want to run QATK on multiple nodes.
I have added paths of license, mpiexec.hydra (from libexec) & atkpython (bin) in ~/.bashrc added.
next I run the following commands on terminal.
1. mpiexec.hydra -f host_file -n 200 -ppn 40 atkpython filename.py > output.log
(host_file contains list of node information)
I get the following errors:
i) /etc/tmi.conf: No such file or directory
ii) DAPL startup: RLIMIT_MEMLOCK too small
2. mpiexec.hydra -n 200 -ppn 40 atkpython filename.py > output.log
In this case although I mention 200/40= 5 nodes but it runs all calculation on single node & not on expected 5 nodes.
KIndly provide a solution!
