Hello, I am trying to use R1.7 on Linux. I having some problem with memory. The task has to handle 100 files of 10MB (each file is .CEL file) and is related to microarrays. I am trying to run this task on a 2GB or a 4 GB node of a Bewoulf Linux based cluster. However I am getting this error saying 'array size of 336000KB cannot be intialized'. I have seen the help of R for memory but I

Dear friends, I'm doing a simulation on logistic regression model, but the programs can't work well,please help me to correct it and give some suggestions. My programs: data<-matrix(rnorm(400),ncol=8) #sample size is 50 data<-data.frame(data) names(data)<-c(paste("x",1:8,sep="")) #8 independent variables,x1-x8; #logistic regression model is

hi list, i have a little problem with 2-node RAC using OCFS. the application running on this cluster does heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel. the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000 while %util=100% (device was saturated) from kernel's POV. i did some

I have a file Server CentOS 5.10, its on the internet, so I compress all csv into one file using (tar -czvf compressed_files.tar.gz *.csv) on this server so that I can download them as one compressed file to save bandwidth, Disk space on this server available is 50Gig, so when I copy the files onto Redhat EL 5.9 and decompress them using (tar -zxvf *.gz) It decompresses maybe 80% then get error:

Hi everyone, I am trying to compile the latest samba package (2.0.17) following the usual steps ./configure --with-smbmount --with-pam make And make reports errors when compiling smbmount.

Hello list First of all: Good work and thanks for GlusterFS! I'm totally new to GlusterFS, but i like it a lot and think about migrating my NFS setup completely to GlusterFS. But i ran into some problems with my chosen structure. Hopefully someone can help out. The first questions: i ran into some performance issues with a certain structure/setup and like to know (before i continue testing)

I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way? Cheers,

I have two variables, both numerical. I would like to find the unique values of the pairs, in other words, unique coordinates if I were to plot them. I also need to know how many pairs there are, but I guess I can use length() if I can somehow isolate the unique pairs first? Thanks a lot! Bonnie Yuan

Hi, I''m trying to setup my box as described below: - The Dom0 exports two disks as physical devices to the DomU - DomU use the two devices to assemble a software raid device (/dev/md0) - On the /dev/md0 I create a lvm volume group and lvm volumes on it. Everything seems to work fine if the lvm volumes on the DomU are lightly used. Under heavy load the DomU freeze up immediately. The

SYSTEM: rh6x based system, 2.2.19-6.2.7 rh errata kernel + 0.0.7a patch, I rebuilt rpm for i686; celeron466, 64MB, PIIX4. root fs is on software raid1 ext2, 6 additional fs's on software raid1 ext2. There's a 3rd HD, not mirrored, which is mounted ext3. EXT3-fs: mounted filesystem with ordered data mode. I enabled journal with tune2fs -j with unmounted fs. The 3 HDs are tuned with

I have a CentOS6.3 SAMBA file server. All the users are on a Windows Server 2008 Active Directory Domain Controller and authentication is done using Winbind integration on SAMBA . Everything works well except that if someone logs on to the Samba Server, they see all the shared folders there and also a folder with their own name %USER%. This Folder is not accessible, one cannot enter into this

I'm doing a text mining project where I have to manually enter a double quote as an element inside a vector. I tried char[10]='"'#where i enclosed the double quote in a pair of single quotes. But the result is [1] "\"". Somehow a back slash is added automatically. I also tried to enclose the double quote in a pair of double quotes. That didn't work either.

I'm running samba 2.2.3a-6 under Debian (testing) and I am having a heck of a time getting Windows 2000 to print to my printer. I keep getting that "Access denied, unable to connect" message. At one point I had it so you could print test pages, but as soon as you tried to print from an application, it would break. However, that doesn't even work anymore. I've been reading

Hello All, I have a production server that is running 2.2.20. This server *has* to be up 24X7 - what I'm wondering is: 1) Is ext3 on 2.2.20 rock stable? Or, would you recommend that I just stay with ext2? 2) I have looked far and wide for a the ext3 patch for 2.2.20 - where can I find it? 3) Were are the e2fsprogs that are appropriate to run with the 2.2.X kernel series? Thanks,

Hie I lost my CentOS 7 root password, so I tried booting the OS in single user mode but it prompts me for the root password when the system boots, Any ideas? Regards Bonnie

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so

I have spent much of the day today researching performance tuning with samba. I have tried everything that I can find out about how to make performance faster. I checked disk performance with Bonnie, installed FTP and tested a transfer that way, achieving 6-7 MB / second. about 30 seconds for 150 MB file. I was finally able to achieve those speeds on a file transfer to the server through

Because I'm a masochist, I decided to port my previous (and much older) Samba configuration running a (much older) Slackware implementation to a (much) new server (running Debian Jessie) without actually looking at how to migrate it. Great fun, lots of problems to solve now. The problem of the moment: /var/log/samba/log.smbd tells me it cannot find the domain info in the ldap backend.

This is has been bugging me for a long time. Nobody around me seems to have this problem. I hope someone on the forum could help me. When I generate a R graph and want to bring the image into Word. I cannot copy and paste it like many of my classmates can do. The "Select" in Edit menu have all options grayed out. So what I ended up doing is to save it as pdf file and bring it
