Hi, I just noticed this article, http://www.howtoforge.net/fully-utilizing-your-x-core-cpu which uses http://code.google.com/p/ppss/ for parralel processing. So, can anyone tell me if parralel processing happens automatically on CentOS, or would I need to use this script as well? We mainly have Dual Core & Dual CPU, Dual Core (i.e. 8 cores) servers and it would be benefitial to know whether

Hi, i tried to find the answer but didn't so my apologies if the question is obvious ! I'm trying to parallelize the following R code : pk2test = c(1:16,(12*16+1):(12*16+16),(16*16+1):(16*16+16),(20*16+1):(20*16+16)) score.mat = matrix(nc=16*4,nr=16*4) for(i in 1:(16*4)) { for(j in i:(16*4)) { score.mat[i,j] = score.mat[j,i] =

Hi there! I have become a big fan of the 'foreach' package allowing me to do a lot of stuff in parallel. For example, evaluating the function f on all elements in a vector x is easily accomplished: foreach(i=1:length(x),.combine=c) %dopar% f(x[i]) Here the .combine=c option tells foreach to combine output using the c()-function. That is, to return it as a vector. Today I discovered the

Hi, I'm using the Umax Astra 610p scanner (parallel port scanner). Unfortunately, it is not supported by sane as Umax is not publishing specs. Searching on google I found out that some people got it working using vmware but nobody could get it working with wine. That is surprising me because people seem to get lots of complicated windows applications working but not a small scanner

Dear all, I would like to ask your help understand the subsequent steps for making my program faster. The following code: Gauslist<-array(data=NA,dim=c(dimx,dimy,dimz)) for (i in c(1:dimz)){ print(sprintf('Creating the %d map',i)); Gauslist[,,i]<-f <- GaussRF(x=x, y=y, model=model, grid=TRUE,param=c(mean,variance,nugget,scale,Whit.alpha)) } creates 100 GaussMaps (each

Hey guys, I have an application that requires a USB Key for it to run. I am running FC5 and have managed to install the application. It runs, but asks me to check the dongle. The dongle is a hasp dongle. I also have parralell versions of this dongle. Is there anyway I can get this to run, it is really essential in my roll out of linux machines at work. I have seen that there are drivers

Hi, I've been testing different methods and I'd like to have some advice. I want to perform a cold backup once a week on the Oracle DB, and put it on tape. I'm using EMC Networker for backup software, and I am not too at ease with the fact of doing eveything with Networker, because if there is a problem with the backup, the Oracle DB might not come up after the backup run. So

Dear list members, Any help on this efficiency issue would be greatly appreciated. I would like to find the most efficient way to run a non-vectorized function (here: fisher exact test p-value) iteratively using 4 matrices with identical dimensions. And as a result I aim for an array with identical dimensions containing the corresponding p-values. Please consider some code using a trivial

Hi. To begin with, I have a freshly built RedHat Linux 8.0 box running samba 2.2.8a. The kernel version is 2.4.18-14. I downloaded and compiled samba from source. I am using LPRng-3.8.9-6 as my printing system. The attached printer is a Lexmark Z22 printer and it is attached to the parralel port. Problem: For the life of me, I can't get NT type clients, NT4, 2K and XP to print to samba.
