[QE-users] ERROR(FoX) when executing crossing nodes

[Duc-Long Nguyen]

Dear all,

Since the release of QE 6.2.1 I encountered the error message as 
following when executing parallel pw.x on multi nodes:
-----
ERROR(FoX)
Cannot open file
-----
There is no errors when running parallel on single node with the same 
input file. I did not encounter this error using previous version of QE 
like 6.2, 5.4.0 with the same make.inc (or make.sys).
Attached please find the make.inc and the output file.

With best regards,
Duc-Long
