[Wien] "remotemachine: Undefined variable." coming from lapw1para_lapw and lapw2para_lapw

[Steven Hahn]

Dear all,

I am trying to setup the fine-grain parallel (mpi) version of WIEN2k  
7.3 on our cluster. I successfully compiled the code, but received an  
error "remotemachine: Undefined variable." when executing "x lapw1 -p  
-c" on the test_case benchmark. Investigating this problem I found  
that adding  "set remotemachine = $machine[$p]" before line 497 of  
lapw1para_lapw allows the benchmark to complete. Testing the full  
iteration with run_lapw on a different case, I had to add the same  
line before line 315 of lapw2para_lapw for WIEN2k to finish without  
errors.

I've tried recompiling everything a second time from the tar file,  
but the problem persists. I did notice that line 496 of  
lapw1para_lapw and line 314 of lapw2para_lapw (set remotemachine =  
`head -1 .machine[$p]`) is missing after the compilation. Adding this  
line by hand gives me a new error message (set: Variable name must  
begin with a letter). This problem is quickly spiraling beyond my  
familiarity with the program. Have others had problems with the mpi  
parallel code? Is this a bug in the code, and if not what setting do  
I need to change? Is the workaround described above correct, or are  
there other files I need to change for proper operation?
