similar to: increasing the # of socket connections

Hi, I am attempting to implement a mixed (windows/linux) snow sockets parallelism in R, but am running into difficulties similar to a post made Aug 31, 2006 under the same subject heading. I feel like I may be one or two non-obvious steps away from getting it all working, but I'm stuck. If anyone can shed some light on this (I believe Prof. Tierney stated that he has successfully run a

Hi, I compiled openssh 2.1.1p1 on Irix 6.2 with MIPS 7.2.1.2m compiler. All works fine except the yppasswd command from Irix (it's no NIS-problem, same with rlogin works): Logged in with 'ssh machine -l user1' # who user1 ttyq0 Jun 19 15:17 (xxxxx.iwr.uni-heidelberg.de) # ypcat passwd |grep user1 user1:xxxxxxxxxxxxx:1535:1500:User1:/usr/people/user1:/bin/tcsh # ypcat passwd |grep

Hi there again, I have a problem with the "parse"-command. First of all, I show you in a simplified way, what I am trying to do and what "R" answers: > test [1] "u.g$par1, u.g$par2" > mode(test) [1] "character" > ausdruck <- parse(text = test) Error in parse(file, n, text, prompt) : syntax error in "u.g$par1,"

Hi list, Is there a way to process R commands in the background other then using R in batch mode? I'm looking for the equivalent of the & operator on the *nix commandline. Cheers, Koen

Hi, I am a newbie to R and trying to implement parallelism in R. I am currently using R-2.3.1, and Cygwin to run R on Windows xp. ssh and all are working fine, When I try to create a socket connection as makeSOCKcluster(c("localhost","localhost")), it just waits for the other prcess on localhost to get created and respond. But this other process is

Hello, 3.7.x kernels prevent my laptop with Optimus VGA from suspend to disk with an PFIFO write fault in PCOPY0, see kernel log below. During the 3.6.x upto 3.6.11 suspend worked without problems. lspci -v info of the VGAs is attached. What may I do to debug this further ? Thanks for any help and greetings, Hermann Jan 30 00:32:41 seba kernel: [ 69.468486] nouveau [ DRM] suspending

Dear list, i have some problems using the snow package to create a SOCK cluster. The errors just occour irregularly but it seems to me that they occour when I try to create more than one cluster on the same machine via different R instances started via submitting LSF jobs to a cluster. Does anyone have an idea how to solve this or where to start digging for solutions? The error messages

Hi I try parallelising some code using the snow package and the following lines: cl <- makeSOCKcluster(8) pfunc <- function (x) (if(x <= (-th)) 1 else 0) ###correlation coefficient clusterExport(cl,c("pfunc","th")) cor.c.f <- parApply(cl,tms,c(1,2),FUN=pfunc) The parApply results in the error message: > cor.c.f <- parApply(cl,tms,c(1,2),FUN=pfunc) Error

Hello, I have a samba 1.9.18p4 server running as a domain master browser on a subnet, with some clients distributed on other subnets. If there are only Win 95 clients on a subnet, browse sync works - but not if there are Win NT 4.0 SP3 machines on that subnet. Error from nmdb (at log level 3): sync_with_lmb: Initiating sync with local master browser MAILHEIDELBERG<0x20> at IP

Thanks for the reply Rowland (and sorry for replying twice). I actually used the wiki you linked to setup the dc. I just added those idmap settings because getent could not list my samba users after setting it up, due to your mail I realised I only needed the winbind options to make it work. The original problem still remains though, using \\SMB.WIE I can only access netlogon and sysvol, using

Hi, While I suspect that this is an issue peculiar to my machine (Debian squeeze amd64, R version 3.0.1, up-to-date packages), I'm hoping that somebody on this list may be able to give me suggestions on how to troubleshoot and fix the following: > library (snow) > cl <- makeSOCKcluster(c("localhost","localhost")) sh: 1: RunSnowWorker: not found I presume/hope

Thanks a lot for your help so far. The main reason I do not use vms is that the server is pretty limited in RAM so this would only be my last resort. To prevent confusion: srv.wie (192.168.1.50) is the same machine as smb.wie (192.168.1.55), I seperated them just now to debug the problem. > These look like they are being run on the DC, what about from the > windows clients ? > I did

Hi folks, I have a production server that's currently running 5.0 with all updates. What's the easiest, or perhaps best way to upgrade it to 5.1, with minimal down time? The downtime is critical, so I need to have it be a short as possible. I can live with an hour or two, but larger is going to be a pain. Suggestions? -- W | It's not a bug - it's an undocumented

Hi. I have some problems trying to make cluster via "snow" package and haven't found a solution for my problem in archives and relative topics. I installed ssh server using cygwin and set a password-less SSH Login. In R session after starting ssh service: > system("ssh 10.10.5.15 date") Tue Nov 22 16:22:36 AST 2011 But when I make connection: > con <-

Hello All, I can run the "lower level" functions OK, but many of the higher level (eg. parSApply) functions are generating errors. When running the example (from the snow help docs) for parApply on MacOSX 10.5.5, I get the following error: cl <- makeSOCKcluster(c("localhost","localhost")) sum(parApply(cl, matrix(1:100,10), 1, sum)) Error in

Hello all; I'm trying to execute parallel jobs trough library snow on a cluster built through torque/PSB. I'm succesfully obtaining the cluster with: >system("cat $PBS_NODEFILE > cluster.txt") >mycluster <- scan(file="cluster.txt",what="character") >cl <- makeSOCKcluster(mycluster) The only problem, at the moment, is that if I use

I'm working with snow and created a local cluster. So far, the same code has always worked (please see below). However, now I receive a message that the connection with the nodes cannot be opened. I restarted my workstation but that didn't help. Is there a known solution for this problem? Thanks a lot for any help. bram foubert library(snow) cl =
