[Wien] machines file ... again

[Griselda Garcia]

Hello all!

I an trying to set up a parallel calculation on a PC's cluster (10 dual 
machines, each one is called fisnodeX). When I use the K-point 
paralellization and run the program as run_lapw -p, everything is ok.

[griselda at clustersvr si-bulk]$ more .machines
granularity:1
1:fisnode2
1:fisnode3
1:fisnode4
1:fisnode5

[griselda at clustersvr si-bulk]$ testpara_lapw
 
#####################################################
#                     TESTPARA                      #
#####################################################
 
Test: LAPW1 in parallel mode (using .machines)
Granularity set to 1
Extrafine unset
 
    klist:       8
    machines:    fisnode2 fisnode3 fisnode4 fisnode5
    procs:       4
    weigh(old):  1 1 1 1
    sumw:        4
    granularity: 1
    weigh(new):  2 2 2 2
 
Distribution of k-point (under ideal conditions)
will be:
 
1 : fisnode2(2) 2k
2 : fisnode3(2) 2k
3 : fisnode4(2) 2k
4 : fisnode5(2) 2k

Then I try to use the fine grained version of parallelization, now my 
machines file (using one processor of each node) is:

griselda at clustersvr si-bulk]$ more .machines
granularity:1
1:fisnode2 fisnode3 fisnode4 fisnode5 fisnode6 fisnode7 fisnode8 fisnode9
lapw0:fisnode1:2

[griselda at clustersvr si-bulk]$ testpara_lapw

I do not realize what it is wrong in the machine file. Why just one processor 
will be used to calculate the 8 Kpoints?. 

I read several times the user's guide but i can not get running the mpi 
version.

The lapw0 works fine with two processors but lapw1 does not run. The dayfile 
file is:

I do not find any clue about the errors.

I will really appreciate your help.
