Rmpi openMPI error

Hi,

We have been using Rmpi and openMPI for a long time and recently upgraded to R 2.13.1, openMPI 1.4.1 (also
tried 1.4.3), Rmpi 0.5-8

We are now getting the error shown below.  Have also tried to roll back to our previous versions but have been
unable to get this to work.  It seems to be Rmpi as we have no issues with mpirun working (locally or across
machines).  Below if a copy of my terminal session.  Notice that the first run works but the executing the
exact same run again it fails?  Any suggestions/help would be much appreciated.

Re: Installing Rmpi on hpc

Looks like you are building the package with the system compilers
and not the OpenMPI wrappers for them, hence missing some of the
libraries that the wrappers pull in.

I think you need to set things up for the build using R's
Makevars file and/or overwriting the compilers from the
command line.

I have had success building like so

$ /usr/bin/R CMD INSTALL \
   --library=/opt/Rlibs \
   /srv/global/work/buckleke/Srcs/R-parallel/Rmpi_0.5-9.tar.gz \
   --configure-args=--with-Rmpi-type=OPENMPI \
   --configure-args=--with-Rmpi-libpath=/usr/lib64/openmpi/1.4-gcc/lib \
   --configure-args=--with-Rmpi-include=/usr/lib64/openmpi/1.4-gcc/include

or similarly, on a different system, like so

$ cat ~/.R/Makevars
CC=mpicc
SHLIB_LD=mpicc
$ cd /local/scratch/kevin/Build/RMPI
$ gtar xf Rmpi_0.5-8.tar.gz
$ cd Rmpi
$ patch -Np1 -i ../Rmpi-ECS_NetBSD-patch.diff
$ cd ..
$ R CMD INSTALL --library=/vol/grid/pkg/R/Rlibs Rmpi \
  --configure-args=--with-Rmpi-type=OPENMPI \
  --configure-args=--with-Rmpi-libpath=/usr/pkg/lib/openmpi \

mpicc support for R packages

Hi folks,

 

If you’ve ever looked at the configure.ac file for the Rmpi package, you’ll see that it’s 281 lines of scanning several environment variables and then attempting to set LDFLAGS and CPPFLAGS for the most popular MPI implementations. This prohibits non programming experts from installing the Rmpi package without knowledge of these environment variables and the correct values for these variables. An alternative would be to allow the package to compile with the “mpicc” compiler, which most MPI implementations provide as a wrapper with the correct library and include flags.

 

The package build system allows a package to specify additional compiler flags, but it does not allow the specification of a different compiler. I’ve written a patch that is targeted specifically for the “mpicc” compiler, this should avoid the issue of a package compiled with the “foobar” compiler when the interpreter was compiled with the “quux” compiler.

 

I’ve attached a 22 line patch to the svn trunk of the R development repository that allows a package to use the “mpicc” compiler by setting the environment variable “R_USE_MPI”. I submitted an earlier patch to the R-devel mailing list, but I didn’t hear anything back and that patch was broken (sorry). To test the new patch, I have been able to successfully compile with packages that use the R_USE_MPI variable and packages that do not use it. As R provides built-in support for OpenMP pragmas, this patch would help provide built-in support for MPI invocations as well.

 

Thanks,

--Michael

Re: mpicc support for R packages

Hi Michael,

Thanks for the patch. If I understand correctly, we need to pursuit R
development term to change the default compiler to mpicc in case the
environment R_USE_MPI is detect (use your patch). On Rmpi part,
configure.ac needs to detect the environment R_USE_MPI at the beginning
and acts accordingly.

Once  mpicc is used instead of cc, the compiling of Rmpi should be much
easier except auto loading package test at the end. Rmpi may not know all
additional libs during loading.

Thanks,

Hao

Re: mpicc support for R packages

Yes, this should be the plan to incorporate these changes.

doMC and RWeka

Everyone,

I recently converted the caret package do use foreach for
parallelizing resampling computations, such as cross-validation.

Below is an example that approximates what caret does. When using
foreach with dopar and no parallelization, things work fine.  For
example, if I run the code below without doMC loaded it, works fine.

If I run the code below (Rweka model and multicore), the workers start
but do not appear to use any CPU time.

If I run first without doMC then load doMC and 2 workers, I get ‘#
fatal error: mach_msg (send) failed: 0x10000003’ (much more
information is below) .

The code below with doMPI also works without error.

Any ideas?

Thanks,

Max

Re: doMC and RWeka

Hi Max,

I think the key information in that huge error dump is:

   Application Specific Information:
   *** multi-threaded process forked ***

This suggests to me that the error was caused by the
forking done in mclapply to start the worker processes.
That would explain why doMPI works.

If that's the case, you probably can't use M5Rules with
doMC/multicore.

rzmq package

Just a quick post on a new package I've been wrapping up, rzmq.

https://github.com/armstrtw/rzmq

Finding inspiration in JD Long's segue package, and frustration with
the config steps involved in dynamically updating the older debian
distribution that Amazon uses for it's emr machines, I decided to try
to hit the ec2 machines directly using my own ami.

The zmq messaging patterns allow one to distribute jobs across many
nodes, but for now a simple example with only 1 micro instance.

the remote server:

ubuntu <at> ip-10-243-90-36:~$ cat remote.server2.r
#!/usr/bin/env Rscript

library(rzmq)
context = init.context()
in.socket = init.socket(context,"ZMQ_PULL")
bind.socket(in.socket,"tcp://*:5557")

out.socket = init.socket(context,"ZMQ_PUSH")
bind.socket(out.socket,"tcp://*:5558")

while(1) {
    msg = receive.socket(in.socket);
    fun <- msg$fun
    args <- msg$args
    print(args)
    ans <- do.call(fun,args)
    send.socket(out.socket,ans);
}
ubuntu <at> ip-10-243-90-36:~$

and the locally executed code:

estimatePi <- function(seed) {
    set.seed(seed)
    numDraws <- 1e5

    r <- .5 #radius... in case the unit circle is too boring
    x <- runif(numDraws, min=-r, max=r)
    y <- runif(numDraws, min=-r, max=r)
    inCircle <- ifelse( (x^2 + y^2)^.5 < r , 1, 0)

    sum(inCircle) / length(inCircle) * 4
}

print(system.time(ans <- zmq.lapply(as.list(1:1e2),
                                    estimatePi,

execution.server="tcp://ec2-184-73-102-95.compute-1.amazonaws.com:5557",

sink.server="tcp://ec2-184-73-102-95.compute-1.amazonaws.com:5558")))

print(mean(unlist(ans)))

yields:
warmstrong <at> krypton:~/dvl/zmq.test/test.ec2$ Rscript lapply.exmaple.r
   user  system elapsed
  0.010   0.010   7.007
[1] 3.140964

Anyway, I'll post up a better example tomorrow that actually uses more
than one machine.

Wicked!  There are so many of us here who are ZeroMQ fanboys.  Were you aware

You have a bug in that you use Rscript in lieu of littler :)

Nicely done. Looking forward to more.

Cheers, Dirk
