search for: 1.4gb

To whom it may concern, I am a student from Peking University, China. I am currently doing some microarray data analysis research with Bioconductor package of R. Problem arises when I try to import into R my dataset which contains 109 samples (total size more than 1.4 GB). The memory limit of R makes importing all the samples into one AffyBatch object a "mission impossible" for me.

I'm trying to read in datasets with roughly 150,000 rows and 600 features. I wrote a function using scan() to read it in (I have a 4GB linux machine) and it works like a charm. Unfortunately, converting the scanned list into a datafame using as.data.frame() causes the memory usage to explode (it can go from 300MB for the scanned list to 1.4GB for a data.frame of 30000 rows) and it fails

Hello, Thanks to much help from Timo Sirainen, I now have a running dovecot on my Mac, that works great both with mutt and Mail.app. I'm going to have a lot of mail stored there (about 40000 messages for 1.4GB in 30 folders), and I was wondering if it was better (in terms of performance and stability) to directly access the mail using the maildir hierarchy, or access it using local IMAP.

I know this is more of a general unix question, but the thread about the last kernel update, and memory usage got me to looking and thinking. Given a system with 2 Gb of memory, and at peak usage, top reports considerably less than the 2 gig amount in use, as well as system monitoring that never shows all available memory used, what would happen if you just turned swap off, and let memory

So, when I embark on the next ThinLTO try build, probably this Sunday, should I append -Wl,-plugin-opt,jobs=NUM_PHYS_CORES to LDFLAGS and run ninja without -j or -jNUM_PHYS_CORES?

List, I've got a process(s) that have been exiting on a signal 11, but not all the time. I suspect it's memory related, and I was wondering, is there any way to tell exactly how much memory a particular process has in use at the point it sigsev's ? I can't sit here and watch top or the system monitor, but thought maybe something might be saved somewhere after the fact.

Maybe somewhat of a vague question, but what would constitute a moderate and a heavy load as depicted by "top" on any particular machine? I am trying to justify running this machine with near 100% cpu utilization on both, with load averages between 5 and 5 according to top. I don't particularly see any significant slowdown in the running processes, but there is a chance the disk

Hi, I believe I have significantly improved [dpq]wilcox functions by implementing Harding's algorithm: Harding, E.F. (1984): An Efficient, Minimal-storage Procedure for Calculating the Mann-Whitney U, Generalized U and Similar Distributions, App. Statist., 33, 1-6 Results on my computer show (against R-2.9.1): > system.time( dwilcox( 800, 800, 80) ) user system elapsed 0.240

http://dovecot.org/test/ Again only mbox fixes. I found some more bugs which could have also caused some of the mbox problems that people reported. They were found when I today thought I'd again do a bit of testing with my favourite 1.4GB mbox. Then I thought I might as well see how it compares against UW-IMAP. First a bit of explanations how they work internally: Dovecot 1.0-test24

I have a usb drive, /media/disk and I want to reformat it. There are several questions that come up: How can I determine the current format? Do I use the mkfs command? Many thanks... Todd -- Ariste Software Petaluma, CA 94952 http://www.aristesoftware.com

I've been doing a number of similar measurements, and have come to the same conclusion. R is currently very conservative about memory usage, and this leads to unnecessarily poor performance on

I'm getting "unexpected EOF in read_timeout" when dealing with large collections of files. The root path is /files, which has 1.4GB of data in 483260 files in 5328 subdirectories. I tried setting "--timeout=600" as a test, but it is still timing out after about 30 seconds. Shouldn't this do it? Or am I possibly having network connectivity issues that may be

Greetings! Samba works great for mounting OSX shares on Linux, or vice versa. However, when I mount an OSX share on Linux, I get weird switches in ownership and permissions. Take these examples from two Linux machines (one and two), running Debian sid and Samba 3.0.0final-1, mounting a directory on an OSX 10.3. First, what the OSX machine shows through an ssh session: [osx:~/Desktop]

I am sharing some of my personal videos on a local network via Ubuntu 9.10/Samba 3.42 on my wired PC to wireless Windows XP and Vista users with a 802.11g router in between. Some of the movies can stream fast enough to watch uninterrupted, while others seem to skip often. I searched online to see any optimization techniques and found this is a popular one for the /etc/samba/smb.conf file:

Hi there, I am pricing out a dell 840 (low end file server) that will run latest centos. Can anyone recommend a good tape drive/card combo with centos? The drives (to be backed up) in it will be a raid 0 - 500gb. Thanks in advance! Dustin

Well, sometimes startx reboots my computer. Other times is does nothing except slow it to a halt for a while. Sometimes is locks up. I am using init level 3. At the command line, everything looks fine, and I can do whatever commands I want. When I type startx, then things go down the tubes. What doesn't happen: X never starts No error messages get posted to dmesg no log is generated in

Hi Junaid, Sorry about the confusion, indeed I gave you the wrong output. So let's start to the beginning. I disabled quota and I reactivated it My configuration : Volume Name: venus Type: Distributed-Replicate Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: ylal3020:/soft/venus Brick2: ylal3030:/soft/venus Brick3: yval1000:/soft/venus Brick4:

This is really strange. Day before, I updated the machine here (x86_64) and all went normal. I rebooted, and everything came back just as I expected. Next morning, I noticed one of my jobs during the night had finished, but finished late by about 8 or 9 minutes. I really didn't think much of it, but after looking at jobs running today, I'm seeing the same thing. Processes that
