??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" The

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

Recently, with LSM (linux security modules) interface growing stable, it is becoming easier to implement different access-control systems for linux. There are already several projects using different approaches to the access-control problem. Each of them has its own meta-info for each file. When syncing two hosts which use some security module, one needs to sync this meta info for each file

Dear R People: I'm running Rmpi on a single machine and I have the following statement from the command line: mpirun -np 3 ./R --no-save < eek1.in >stuff4.out The stuff4.out file only contains the third result. Is there a way to fix this such that it shows all 3 sets, please Thanks in advance, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical

Hi, I am working on a 64-bit rocks cluster and am relatively new to the R package. I am trying to get Snow working with R and Rmpi and have run into the following issue. R is able to load the Rmpi and snow libraries and is able to run simple commands both interactively and batch as follows: -------------------------------------------------------------------------------------------------------

Hi,there I'm doing some R batch jobs in Unix. Something like R <prog1> output1 --save & R <prog2> output2 --save & prog1 and prog2 are running at the same time and they are essentially same except it contains different parameter values. I was wondering if two processes will affect each other? Hopefully they are two independent jobs. It's a beginner's question

I'd like to announce the availability of the new "doMPI" package, a parallel backend for the "foreach" package, which acts as an adaptor to the "Rmpi" package. The package has been uploaded to CRAN and is now available. Like the "doSNOW" package, "doMPI" allows you to execute foreach loops in parallel using "Rmpi" as the underlying

Martyn, you write > I don't think restart() is necessary - it just seems like an invitation to > bad programming to me. It's needed when comparing, say, the time to convergence (if at all) of various iterative processes, for each of a few hundred simulated values. For example one wants basically function(data){ summary<-rep(NA,1000) for(i in 1:1000){

In another thread, a user was told to execute: wine 'prog1 prog2' to run them both at the same time. I haven't been able to figure out how to do that with my situation. I tried this wine "'c:/Program Files/wdisplay/WeatherD.exe' 'c:/Program Files/ Google/adwords_editor.exe'" but got this: wine: cannot find ''c:/Program

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 Jim

Question 1: I have a long list of variable names such as first <- c("one","two","three") and what I want to do is create a list of lists ... where the names of each of overall lists components are "one","two", and "three". This is the same result as second <- list(one=list(),two=list(),three=list()) Is there a way to exploit

Greetings. I see a warning message while compiling OpenMPI and would appreciate it if you tell me what it means. This warning happens with any OpenMPI > 1.6.5. Even before starting a cluster, just "sessionInfo" triggers this warning. I'm pasting in the message from R-3.3.2 (this is MRO). Do the R parallel package cluster functions violate the warnings described here? >

Hi, Jim. In my case the target (Tilera) doesn't have a full 32-bit mult operation and to do so it has to accumulate results from three 16-bit mults, by retaining operands and the result across in the same registers. However the ISel DAG thinks its a CSE case. Please note this is not a MAdd/MSub triad. How could I do this by defining such a sequence or the pattern in the .def file itself for

Ah, OK. I think I understand much better now. Thanks! You shouldn't need bundles for that sort of thing. A custom lowering or a fancy pattern should be sufficient, depending on the details of how your target is defined. For patterns, looks at the various targets use of the Pat<>, Pattern<>, ComplexPattern<> and related classes in the .td files. For examples of custom

Thank you very much Steve. Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.

Hi Jim. I'm doing custom lowering but here I have a very basic issue and the situation is like this - [Original Op] Mul Dest, Src1, Src2 [Expanded from EmitInstrWithCustomInserter] Step1 Dest, Src1, Src2    <=== BuildMI(..., Step1, Dest).addReg(Src1).addReg(Src2) Step2 Dest, Src1, Src2    <=== BuildMI(..., Step2, Dest).addReg(Src1).addReg(Src2) Step3 Dest, Src2, Src1    <===

Congrats to all those who have contributed to R over the past year. As with last year, for New Year I would like to list the top 10 features I would like to see in R. The first three are the most important. 1. Scripting With this feature it would be possible to call R like this as a filter: R -f myprog.R infile1.txt infile2.txt > outfile.txt or prog1 | R -f myprog.R | prog2
