[Wien] WIEN2k benchmark

Dear W2k users

I have run the benchmark on an SGI ALTIX (4 Itanium2 1.4 GHz processors)
machine which we are planning to buy. It has ifc+mkl and for the 
sequential run, it gave a time of 126 secs (x lapw1 -c). Now we wish to 
run the benchmark in parallel mode. The code has been compiled with the 
mpi libraries + ScaLapack and PBlas. I want to know whether it will run 
properly by giving the command (x lapw1_mpi -p -c) or we have to do the
run init_lapw, followed by run_lapw -p -c for 1 iteration?

I am asking this question as I personally do not have access to the 
Machine under trial and the company engineers who are running the code 
surely do not want to learn the whole running process.

Any ideas will be helpful.

Regards
Sharat Chandra
