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 any applications on the server could automatic...

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] =

...tor 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 'bigmemory' package, and I would like to contruct a big.matrix in a parralel fashion row by row. To use foreach I see no other way than to come up with a substitute for c in the .combine option. I have checked out the big.matrix manual, but I can't find a function suitable for just that. Actually, I wouldn't even know how to do it for a usual matrix. Any clues? Th...

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

...e,Whit.alpha)) } creates 100 GaussMaps (each map is of 256*256 dim) and stores them in a matrix called Gauslist. This process takes too long, so I was thinking if you can help me understand what should I do to make it run in parallel (in work there is a system with 16 cores). There is mclapply (parralel version of lapply) . If I make run my code run with lapply then I will be able to run it with mclapply also (they have same syntax). If I understand it correct the sequence for doing that is to understand the following: for..loop->lapply->mcapply Can you please help me understand if my for...

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 available on the hasp website, but I dont seem to be able to get them to work with this application, I keep getting: fixme:vxd:VXD_...

hello together! is it already known? that in some distros the windows online game "eveonline" can not be started more then 4 times parralel in the same time? for ex. in fedora knows somebody why? and how i can start more eve.exe at the same time? thx in advice and greets lightmans

...-based backup. I've tried scp'ing the files directly to my backup server, but the operation is too long (120 min). I tried generating a tar.gz directly to my backup server via SSH. A decent 40 minutes, using mgzip (multi-thread gzip), 70 Gigs. 120 minutes for a tar.bz2, using pbzip2 (parralel bzip2) (54 Gigs). A tar sent directly to my backup server is quite huge (318 Gigs). It is then taken to tape on the regular nightly backup. My concerns are: - Time needed to perform backup (downtime). - Time needed to do a recovery. For the backup, sending a tar.gz directly to the backup ser...

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. My smb.conf file is as follows: +---------------------------- [global] workgroup = Popstar netbios name = Paint-Roller server string = Print Server (Samba %v) interfaces = eth0 127.0.0.1 b...
