similar to: MOSIX and ext3-fs

Mosix is a cluster operating system that is a set of kernel patches to Linux on i386 machines. It allows processes to migrate to other nodes on the cluster transparently. See www.mosix.org for details. However, my R processes were refusing to migrate. Using strace, and delving into the R code, I found that it was due to a large number of calls to the system setjmp and longjmp routines - the

Has anyone tried Asterisk on a MOSIX cluster? My concern is if there is any adiitonal laltency when when the processes are moved from on node to another. Anyone tried it yet? thaks, darran ps. Anyone have any info on MYSQL support with Asterisk? I see the conf file but I dont see a database schema to install... -------------- next part -------------- An HTML attachment was scrubbed...

If I patch the 2.4.14 kernel with the grsecurity patch first I get errors while patching the ext3 patch. the link for the grsecuritypatch is http://www.grsecurity.net/download.htm (which ever patch I do first works fine..the onther patch fails) this is the error I get fro patching the ext3 patch second (I get an error inthe same place if I patch the grsecurity patch second) Hunk #1 FAILED at

Hi everybody, I''ve got a little problem when adding HTB support to my SUSE 8.1 by patching its kernel 2.4.19. After i patch kernel getting some errors, the HTB kernel option shows up but when i make modules it finds something wrong with the sch_htb.o module. Could somebody give me a hand on this? Thanks in advance. I get this information when patching (patch -p1 <

Hi all, Thanks for the prompt reply about 2.4.13. I applied the patch after I'd applied the win4lin and mki patches and it fails. The .rej file is included after this message. If you need any further info I'll try and supply it. Thanks Robyn This file is sched.h.rej from /usr/src/linux/include/linux/sched.h.rej *************** *** 399,404 **** u32 self_exec_id; /*

Barry, Would you mind providing the necessary patch for this behavior?

Dear all, I wrote the following batch script on a iMac, and ran it on a linux mosix cluster. tu <- read.table("cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshape.table") tu_reshaped <- t(reshape(tu[1:50,], direction="wide", timevar="tu", idvar=c("rna","lib"))) write.table(tu_reshaped, "cage.mm5.tags.rna_lib.CAA-CAJ.tu-reshaped.table")

Hello fellow samba users, Our company uses samba for all fileshares/printing/PDC on two SUN E3500's. We like to replace these with about 10 Linux 19" XEON (pizza)boxes. The question: Are there any implementation out there using a loadbalancing cluster doing samba? A simple diagram of the setup I have in mind: Users (+/- 500) ||| Headnode(Director 1) - Headnode (Director 2) | Worknode -

Hi all, I was hoping to get some advice about a problem that I realize will be difficult to reproduce for some people. I'm running R 1.7.1 on an openMosix (Linux) cluster and have been experiencing some odd slow-downs. If anyone has experience with such a setup (or a similar one) I'd appreciate any help. Here's a simplified version of the problem. I'm trying to run the

Hi, yesterday I upgraded my kernel to 2.4.15-pre6 (after months of using only ac-kernels) and had my first ext3-error since 0.0.3 . syslog tells me : Nov 20 18:16:31 enterprise kernel: EXT3-fs error (device ide0(3,9)): ext3_readdir: bad entry in directory #47390: inode out of bounds - offset=0, inode=404363549, rec_len=4096, name_len=23 and the system remounted /usr to ro.

I recompiled my kernel to link in ltsp with open mosix. Now wen the client machine boots I keep geting the message: Can not load a ramdisk with an old kernel image Can you tell me why

Hi there, We're currently attempting to explain a slowdown of an LVQ-type parallel analysis we're working on. We are benchmarking our analysis running over openMosix against the same running via SNOW for R. Both perform similarly on small datasets, but on large datasets SNOW drastically outperforms openMosix. However, these results are achieve running SNOW on the default RedHat

Hi, I just wanted to compile my kernel 2.4.13 with the ext3-2.4.13-pre6 patch, but it doesn't work. It seems, that the patching failes by replacing some things in a textfile. Does anyone of you know, if there is a upcoming solution for this? Kind regards Jan Albrecht -- Jan Albrecht Phone: +49-5241-80-88404 System Consultant UNIX/NT Fax:

Hello, Stephen, It seem that in the presence of several jornalling file systems in the kernel some mechanism is needed for proper sharing of the ->journal_info pointer in the task_struct. One journalled file system can indirectly call another during page fault in copy_from_user, quota file modification, or __alloc_pages()->balance_classzone()->shrink_cache()->vm_writeback()

Lo, Is there already a patch out for latest 2.4.6-ac release? I'm pretty sure that the ext3 patch -ac2 can not be applied on this release. Bye. -- the trees the birds the air the grass the water the flies the trees

jbd2_journal_restart() would restart a handle. In this function, it calls start_this_handle(). Before calling start_this_handle()?subtract 1 from transaction->t_updates. If start_this_handle() succeeds, transaction->t_updates increases by 1 in it. But if start_this_handle() fails, transaction->t_updates does not increase. So, when commit the handle's transaction in

Hi, This is not an R question per ce, but I feel like this is a right community to ask it. As a part of our work we run a lot of non-interactive computational jobs. To increase the throughput we would like to distribute the load over the entire network and we are looking at Linux network as a platform. Ideally we would like to be able to submit a job to the network, rather than to a computer, and

Hi, I had ext2 and 2.4.7 kernel , quotas were working ok. Now when all my filesystems are ext3 I figured out that quotas are not working.... if I do quotaon , repquota, quotacheck the programs return 0 without any output..... Does ext3 supports quotas? Nikolai
