Hi,
When I started using USPEX I also had a lot of troubles running this example. I will give some suggestions to check if everything is ok.
1st- See if the command "mpirun pw.x" directly in the terminal correctly runs the quantum espresso. If it is not running, look for the correct path of pw.x
2nd- Remove the "#" from the "numParallelCalcs" and "whichCluster" lines in the INPUT file.
3rd- Set the value of "numParallelCalcs" to 1.
4th- You can see the calculations progress in the output file in the Calcfold1 folder, if quantum espresso is running correctly.
5th- Use a script to run USPEX, so you can save the results in a log file. Here's an example script:
#!/bin/sh
while true; of
date >> log
USPEX -r >> log
sleep 20
done
To run the script use the command "nohup ./"script name" &". If none of these procedures work, post the log and nohup file here. Hope this helps.
