Subject: [mpich-discuss] reading from a read only directory
Message-ID:
<CAJ1ofpd6_bkODsmaf+zoMBsc+hfUu=p0XRd9VKc4U=NVkOhQLA@mail.gmail.com>
Content-Type: text/plain; charset=ISO-8859-1
I got the following error trying to slurp in a large file
(slice-17.pentago) with MPI_File_read_ordered:
rank 0: pentago/mpi/io.cpp:read_sections:397:
MPI_File_read_ordered(file,raw.data(),raw.size(),MPI_BYTE,MPI_STATUS_IGNO
ADIOI_CRAY_OPEN(102): Access denied to file all-1/.slice-17.pentago.shfp.670064
The directory all-1 was read only due to paranoia over accidentally
deleting expensively obtained data. Looking at ADIOI_Shfp_fname in
the mpich source, it looks like this error is intentional: the shared
file pointer routines generate temporary files in the same directory
as the read-from file. I couldn't find any attempts at recovery if
the file cannot be written in that place. This behavior doesn't seem
to have changed since the beginning of the git repository.
Is my reading of the code correct: MPI_File_read_ordered can't be used
on a file in a read only directory?
I can see the motivation for this in the case of noncollective shared
routines: since the other processes aren't necessarily doing any MPI
at the moment, the only way to synchronize is through the file system.
And because there might be all sorts of different filesystems in
operation, the easiest way to ensure that we're touching the right one
is use the same directory. I can't imagine any reasonable use of the
noncollective shared routines, but maybe that's a different
discussion. Is this an unfortunate leak between broken routines which
need questionable trickery and perfectly good routines like
MPI_File_read_ordered?
Thanks,
Geoffrey

Dear sir/madam
Hello.
I am running Ubuntu 12.0.4 LTS (my computer is dual boot with win XP SP3
and ubuntu). I can swear that I have run the example 'cpi' in the package
'mpich-3.0.4'. but now, see the result of executting
soheil@soheil-desktop:~/mpich-3.0.4$ mpiexec -n 4 ./examples.cpi

Also, 'whiching' mpicc and mpiexec both return /user/local/bin/mpicc and
/user/local/bin/mpiexec, respectively.
I mean I have installed mpich before and sat the PATH variable.
I need mpich on my ubuntu. Please help.

Is ./examples.cpi a valid binary for your platform? (Try the `file'
command on it.)
"No such file or directory" is, among other things, what you get when
attempting to execute non-executables.
Cheers,

Subject: [mpich-discuss] MPI_init very slow with more than 3 nodes
Message-ID: <20131128151009.Horde.gT6RZrajp4n2Vpf8bcsTPw1@www.ehu.es>

Goods.
I'm testing a mpich cluster (3.0.4) with 7 nodes quad core, Ubuntu
12.04. The master has the home directory
and the nodes get it by nfs. I have change RPCNFSDCOUN from 8 to 64.
The programs go fine with master and ONE of the other nodes, but when
I start them with more nodes,
MPI_Init (I think so) takes long time (~20 minutes). At these time in
all nodes there is many network
(read and write) and master's hard disk activity. For exemple:
mpiu@u105251:~$ date; mpirun -f fila5 -np 8 test/hello; date
mi? nov 27 15:17:29 CET 2013
Hola desde el procesador u105251. 0 de 8

mi? nov 27 15:36:18 CET 2013
mpiu@u105251:~$
When the programs start, i.e. since the first C instrucction, they run
fine. For that I think that the problem
is MPI_init
Anybody kowns why?
Thank.
