Dear developers and users
I was trying to do a volume optimization and scf calculation with spin polarization in parallel mode. But my both the jobs crashes and I got the following error file. However both cases run correctly when parallel mode is removed.
............................................................................
'LAPW2' - can't open unit: 30
'LAPW2' - filename: case.energyup_1
** testerror: Error in Parallel LAPW2.................................................................................
Also in STDOUT , I see the following particular errors. (
.......................................................................
bash: lapw1: command not found...
.........
FERMI - Error
grep: *scf1dn*: No such file or directory
0.381u 0.507s 1:12.66 1.2% 0+0k 128+1736io 1pf+0w
Test-TiC-VOl-parallel.scf1dn_1: No such file or directory..............................................................................
I copied my machine file and the job file here. But I think this is not correct and I am not sure whether I needs to have lines for lapw2 and lapwsp separately. Any help to get corrected this is highly appreciated.
".machnes" file.............................#

job file is copied below.
# example for 8 nodes
#PBS -l procs=8
#PBS -l pmem=2048mb
#PBS -l walltime=4:00:00
module load wien2k
# change into your working directory
cd $PBS_O_WORKDIR
#start creating .machines
cat $PBS_NODEFILE |cut -c1-6 >.machines_current
aa=`cat .machines_current | wc -l`
echo '#' > .machines
# example for an MPI parallel lapw0
echo -n 'lapw0:' >> .machines
i=1
while [ $i -lt $aa ]
do
echo -n `cat $PBS_NODEFILE |head -$i | tail -1` ' ' >>.machines
i=$((i+1))
done
echo `cat $PBS_NODEFILE |head -$i|tail -1` ' ' >>.machines
#example for k-point parallel lapw1/2
i=1
while [ $i -le $aa ]
do
echo -n '1:' >>.machines
head -$i .machines_current |tail -1 >> .machines
i=$((i+1))
done
echo 'granularity:1' >>.machines
echo 'extrafine:1' >>.machines
#define here your WIEN2k command

Thank you
