[Wien] "if: Expression Syntax." in fine-grained parallel lapw2

[Steven Hahn]

I am receiving another error message during the scf cyle, this time  
from lapw2. If I use just fine-grained parallelization(one line in  
my .machines file), everything runs fine. If I use both fine and  
course-grained parallelization (nodes on two separate lines)  I  
receive the error message "if:Expression Syntax." I traced it back to  
line 143-148 of lapw2para_lapw

set number_per_job2 = `cut -f4 -d: $tmp2`

if ( $vector_split != '' ) then
   if ($vector_split > $number_per_job2 ) set vector_split= 
$number_per_job2
   @ number_per_job2 = ( $number_per_job2 / $vector_split ) *  
$vector_split
endif

If I run with this .machines file

1:node020 node018 node018 node018
granularity:1
extrafine:1
lapw2_vector_split:1

I get the following values

tmp2 = 1 : node020 :  888 : 4 : 1
number_per_job2 =  4
vector_split =  1

If I run with this .machines file

1:node020 node018
1:node018 node018
granularity:1
extrafine:1
lapw2_vector_split:1

I get this:

tmp2=
1 : node020 :  444 : 2 : 1
2 : node018 :  444 : 2 : 2
number_per_job2 =  2 2
vector_split =  1

The script crashes because it can't tell if cannot compare  
$vector_split (whose value is 1) to $number_per_job2 (whose values is  
2 2) because the second is not a number.
