Set the number of threads using openmp with .Fortran?
Hi everybody, I'm trying to develop an R package with Fortran and OpenMP. I wrote a simple hello world but I'm not able to set the number of threads. I found this old email chain <http://r.789695.n4.nabble.com/Set-the-number-of-threads-using-openmp-with-C-td2284685.html> and I tried to set my compile instructions accordingly but i had no luck. *This is my makevars:*

Set the number of threads using openmp with .Fortran?
I got this to work on Linux but it is not working on Windows. *My understanding is that this should also work on windows, is that correct?* If so, what should I do? differently? To get it to work on Linux, I modified my R script as follows: #' OpenMP Hello World #' #' @param nthreads The number of threads that you want to use #' @example #' hello(nthreads=2) #' @export

Foreach %dopar% operator incorrectly load balancing
Dear R-SIG-Debian, I am using R version 3.1.2 with rstudio-server 0.98.113 on debian build 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u1 x86_64 GNU/Linux. I often use the %dopar% operator in from the foreach package to run code in parallel. However, the only other use on the box seemingly installed a few items and suddenly %dopar% will use far more than the number of cores I am specifying and

How to (appropropriately) use require in a package?
Dear All, What is the preferred way for Package A, to initialize a cluster, and load Package B on all nodes? I am writing a package that parallelizes some functions through the use of a cluster if useRs are on a Windows machine (using parLapply and family). I also make use of another package in some of my code, so it is necessary to load the required packages on each slave once the cluster is

Set the number of threads using openmp with .Fortran?
I was able to make some progress by using this <https://github.com/bert9bert/ParallelForest/blob/master/src/Makevars> as a reference. Now: *This is my makevars:* ##### Compiler flags ##### PKG_FCFLAGS = $(SHLIB_OPENMP_FFLAGS) PKG_LIBS = $(SHLIB_OPENMP_CFLAGS) ##### Phony target for R's build system to invoke ##### all: $(SHLIB) ##### Clean target ##### clean: rm -f *.o *.mod

snow: cluster initialization
Dear all, I found a strange thing with the snow package. This will work: y = matrix(1:4, 2) cl = makeCluster(rep('localhost', 8), type='SOCK') parMM(cl, y, y) This will not: y = matrix(1:4, 2) ncore = system('nproc') parMM(cl, y, y) Error in cut.default(i, breaks) : invalid number of intervals I also tried: cl = makeCluster(rep('localhost', ncore),

Una guía de estilo para programar en R...
Hola, He seguido con interés el mensaje de Carlos sobre la guía de estilo para programar en R aparecida en Google y las reacciones que ha generado. En líneas generales creo que la guía Google es bastante floja, estoy de acuerdo con la mayoría de comentarios iniciales de Carlos y en particular con el hecho de que no trata en absoluto (ni lógicamente promueve) la creación de packages.

Bootstrap data frame (Jesús Para Fernández)
Hola Jesús, Si no entiendo mal lo que planteas, has observado unas frecuencias N = c(12, 0, 8, 6, 4, 2) de pedidos acaecidos en 1:6 días, en total n = sum(N) pedidos. Llamemos P = (p1, p2, ?, p6) a las probabilidades ?teóricas? de pedido en cada día. En principio el vector N se puede considerar una realización de una distribución multinomial M(n; p1, ?, p6). P se puede estimar mediante las

[PATCH 1/2] xfs: rename xfs_is_valid_magicnum to xfs_is_valid_sb
xfs_is_valid_magicnum is not actually a generic function that checks for magic numbers, instead it checks only for superblock's one.

Bootstrap data frame
Hola buenas En principio a mí no me parece una mala aproximación. Tal vez se podría intentar adaptar el problema a un modelo de supervivencia, pero tendría que pensarlo. ( https://vimeo.com/142732615 ) De todas maneras, creo que coges días al azar para calcular to "proxy". Aunque yo personalmente cogería días consecutivos porque probablemente el consumo en muchos productos no sea

Package parallel left orphan processes, how to clean-up?
Hi, I've using package DEXSeq that implements functions with nCores for speed-up. The functions work fine, but I found out that the children processes were not terminated, they still hold memory, and new command will start up new children processes. So if I don't manually kill those orphan processes, they will cause problem. I was qlogin to SGE cluster node to run R. From our

Mi script R es muy lento
Hola Carlos, bueno la verdad es que mi pregunta era algo general, cuando no has usado data.table no parece muy intuitivo pasar de la forma de programar a la que estás más acostumbrado (bucles, notación matricial...) a esa otra. Aun no tengo un cálculo complejo concreto pero lo tendré que hacer... solo quería saber si se puede, y parece que sí, asi que será cuestión de empaparse un poco de

Can't setup Windows Print Driver on Samba 3 Server
Hi, I'm trying to store a windows print driver on a samba 3 server (which is sharing a pseudo PDF printer) so that windows users in the domain can automatically have it installed (rather than having to choose a driver from their computer manually). I've tried the methods outlined in the samba howto but I can't get either of them to work. The one where you use a windows machine to

Pregunta (debate) sobre licencia R
Hola buenos días, una pregunta que quiero realizar de R sobre el tema de la licencia y que me inquieta un poco, a ver si alguien me la puede responder de un modo suficientemente claro o referirme a algún sitio donde informarme porque yo por el momento estoy un poco liado.
