foreach hangs when using doMPI on Windows with Microsoft MPI
??I installed Microsoft MPI.
Then installed the foreach and Rmpi packages.
Then built doMPI from source.
mpi.remote.exec works.
foreach hangs with the main process and all worker processes idle.
I launch my script with mpiexec:
"C:\Program Files\Microsoft MPI\Bin\mpiexec" -n 3 "C:\Program Files\R\R-3.2.0\bin\x64\Rterm.exe" --no-save -q -f "MPI Test.r"...

R: mpirun .C and R
...code that will be used for parallel computations
on a Moab cluster. I have written a C++ program and am linking it with R
using the .C command - this works correctly.
Extracts of the r code (as well as the *.sh file) is included below. I
am able to run the code successfully if I remove all of the doMPI
commands. i.e. outs=.C("prog1", all of the args )
executes correctly if one uses a loop. When I try and use doMPI i get
the following errors:
Error in { : task 1 failed - "C symbol name "prog1" not in load table"

Error in { : task 3 failed - "NA/NaN argument"
I'm attempting to run a rather complex routine that involves a few loops, and even some use of foreach and doMPI. I just added another external loop and now get this error message.
Error in { : task 3 failed - "NA/NaN argument"
Is there a way to debug what is causing this error or where? I really have no idea what "task 3" is?
Thanks

creating list of lists
...quot;one","two", and "three".
This is the same result as
second <- list(one=list(),two=list(),three=list())
Is there a way to exploit lapply to convert a list such as first to a list of empty lists such as second?
Question 2:
In a parallel routine using foreach and doMPI have to put calcualted values into a list of lists such as
list(one=one,
two=two,
three=three)
It uses the same (large) list of variable names as first in question 1. Is there a simpler way to accomplish this with a lapply statement?
I've tried several permutations but no luck!...

how to have R tell me which node is being used in a multi-node cluster
Hi all,
I'm trying to use a parallel script on a 20 node cluster, 8 processors
per node. Each node has a name, e.g., "vm0000", "vm0001", etc. Within
a foreach loop, I would like R to tell me what node it is actually
running on. How can this be accomplished? Thanks!
require(doMPI)
cl <- startMPIcluster(16)
registerDoMPI(cl)
x <- foreach(i = 1:16) %dopar% {
<some function that writes the node name out to screen or file>
}
closeCluster(cl)

[R-sig-hpc] doMC - compiler - concatenate an expression vector into a single expression?
Thank you very much Steve.
Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.
Bests,

creating character vector
Is there a way to convince R to create a character vector without using the quotes?
This works
ex1 <- c("first","second")
but when I try this it doesn't
ext <- as.character(c(first,second))
it complains. I have many variables to put into character vectors so dispensing with the quotes would be useful.
Thanks

mclapply returns NULLs on MacOS when running GAM
...foreach' framework takes this separation of *what* to parallelize
(which you decide as a developer) and *how* to parallel (which the
end-user decides) further by so called foreach adaptors aka parallel
backends. With foreach, users have plently of doNnn packages to pick
from, doMC, doParallel, doMPI, doSnow, doRedis, and doFuture. Several
of these parallel backends build on top of the core functions provided
by the 'parallel' package. So, with foreach your users can use forked
parallel processing if they want and, or something else (selected at
the top of their script).

mclapply returns NULLs on MacOS when running GAM
Thanks Simon,
I will take note of the sensible default for core usage. I?m trying to achieve small scale parallelism, where tasks take 1-5 seconds and make fuller use of consumer hardware. Its not a HPC-worthy computation but even laptops these days come with 4 cores and I don?t see a reason to not make use of it.
The goal for the current piece of code I?m working on is to bootstrap many
