[Pw_forum] Length of tmp_dir

[NoahPark]

Dear PWscf users;

When I initially run the code, I get the following message.

>>   /S/n006/home006/f0006/tmpX//    non existent or non writeable.

Now, I comment out the two lines in bottom of input.f90, as the following.

>> ! if (ios /= 0 ) call error('reading', &
>> !                   trim(tmp_dir)//' non existent or non writable',1)

By this modification, the code works almost successfully, except the following behaviors.

 1. when I gave a somehow short string to 'outdir' in input file,
         outdir = '/S/n006/home006/f0006/tmpX//'
    The code works successfully.

 2. when I gave a somehow longer string to 'outdir'  in input file,
         outdir = '/S/n006/home006/f0006/tmpX/tmpX.b/tmpX.b.b//'
    The code iterate with a total energy of a strange value.

 3. when I did not include the string of 'outdir' in input file,
    The code runs successfully, but, 'restart' doesn't work.
    The code fails in reading wavefunctions written in the previous work.

 This may be caused by the constraint in the length of the string of 'tmp_dir'.
 If so, how could I increase its available length.
 If not, would anybody please guess the reason for the observed phenomena ????

Best regards,

Noah
