[Pw_forum] Running parallel in some example of 2 cup is wrong?

[GAO Zhe]

In example 03, the first step is a calculation of CO atGAMMA point.  Thus, you cannot use more than one pool to run it. Why not trympiexec -n 8 pw.x -npool 1 and see how it goes?

My computer is 2 cpu and 8 core of Dell. In some examples are crash. Such as:co.out of example 03 show that 'from d_&_i:error;some nodes have no k points'.
And the environment_varibles of examples I set :

PARA_PREFIX="mpiexec -n 8"
PARA_POSTFIX="-npool 2"


And how odd is when I set :

PARA_PREFIX="mpiexec -n 4"
PARA_POSTFIX="-npool 1"


the example 03 can be work.
 
The similar case occur also in some of other examples.
 
 Please tell what problem is…………thanks.
