Strange - let me have a look at it later today. Probably something simple that another pair of eyes might spot.

Seems like connected problem:
I can't use rankfile with app, even after all those fixes ( working with trunk 1.4a1r21657).
This is my case :
 
$cat rankfile
rank 0=+n1 slot=0
rank 1=+n0 slot=0
$cat appfile
-np 1 hostname
-np 1 hostname
$mpirun -np 2 -H witch1,witch2 -rf rankfile -app appfile
--------------------------------------------------------------------------
Rankfile claimed host +n1 by index that is bigger than number of allocated hosts.

The problem is, that rankfile mapper tries to find an appropriate host in the partial ( and not full ) hostlist.
 
Any suggestions how to fix it?
 
Thanks
Lenny.

Now there is another problem :)

You can try oversubscribe node. At least by 1 task.
If you hostfile and rank file limit you at N procs, you can ask mpirun for N+1 and it wil be not rejected.
Although in reality there will be N tasks.
So, if your hostfile limit is 4, then "mpirun -np 4" and "mpirun -np 5" both works, but in both cases there are only 4 tasks. It isn't crucial, because there is nor real oversubscription, but there is still some bug which can affect something in future.

Although removing this check solves problem of having more slots in rankfile than necessary, there is another problem.

If I set rmaps_base_no_oversubscribe=1 then if, for example:


hostfile:

node01
node01
node02
node02

rankfile:

rank 0=node01 slot=1
rank 1=node01 slot=0
rank 2=node02 slot=1
rank 3=node02 slot=0

mpirun -np 4 ./something

complains with:

"There are not enough slots available in the system to satisfy the 4 slots
that were requested by the application"

but "mpirun -np 3 ./something" will work though. It works, when you ask for 1 CPU less. And the same behavior in any case (shared nodes, non-shared nodes, multi-node)

If you switch off rmaps_base_no_oversubscribe, then it works and all affinities set as it requested in rankfile, there is no oversubscription.

If I remember correctly, I used an array to map ranks, and since the length of array is NP, maximum index must be less than np, so if you have the number of rank > NP, you have no place to put it inside array.

"Likewise, if you have more procs than the rankfile specifies, we map the additional procs either byslot (default) or bynode (if you specify that option). So the rankfile doesn't need to contain an entry for every proc."  - Correct point.

On 5/5/09, Ralph Castain <rhc@open-mpi.org> wrote: Sorry Lenny, but that isn't correct. The rankfile mapper doesn't care if the rankfile contains additional info - it only maps up to the number of processes, and ignores anything beyond that number. So there is no need to remove the additional info.

Just don't want to confuse folks.

Hi,
maximum rank number must be less then np.
if np=1 then there is only rank 0 in the system, so rank 1 is invalid.
please remove "rank 1=node2 slot=*" from the rankfile

I believe this is fixed now in our development trunk - you can download any
tarball starting from last night and give it a try, if you like. Any
feedback would be appreciated.

Clearly a bug exists in the program. I'll try to take a look at it (if Lenny
doesn't get to it first), but it won't be until later in the week.

The rankfile cuts across the entire job - it isn't applied on an
app_context basis. So the ranks in your rankfile must correspond to
the eventual rank of each process in the cmd line.

Unfortunately, that means you have to count ranks. In your case, you
only have four, so that makes life easier. Your rankfile would look
something like this:

rank 0=r001n001 slot=0
rank 1=r001n002 slot=1
rank 2=r001n001 slot=1
rank 3=r001n002 slot=2
