what do you mean by 'doing nothing'?

I think you can try to use '-in' instead of '<' in command line.
for example, if you type pw.x < inputfile > outputfile, nothing printed on the screen. 
Then you could try to type pw.x -in inputfile > outputfile.

hope helps.

by the way I also encounter another situation. If the subnet mask is not consistent among the clusters, problems may be happen. so you may check the subnet mask.

Respected Sir,

I am doing some adsorption studies with anatase(101) surface with ultrasoft pseudopotentials. my surface model is 2x1x2 with 15 angstroms vaccum space. I am able to run in parallel with water adsorbed on the TiO2 surface. the moment when i replaced water molecule with 2-Cyano-3-phenyl-acrylic acid it is not doing any calculations in parallel. According to the process pid it is showing that in all nodes the job has distributed, but doing nothing. I tried with several options with npool and number of processors. please help me in this regard.


yours sincerely,
 
K.Srinivas
