Hello, I am just installing XCP 0.1.1 on a server with 24GB RAM Normally XCP is a 64 bits version but * *uname -a* Linux node012 2.6.27.42-0.1.1.xs0.1.1.737.1065xen #1 SMP Fri Jan 15 16:20:16 EST 2010 i686 i686 i386 GNU/Linux (not a x86_64 version !!!!) * *cat /proc/meminfo* MemTotal: 746496 kB MemFree:...

Hi, I have a problem when using R1.7.0. I have a very large dataset, but I also have access to 24GB RAM on a super-computer. Nevertheless, when using the "lme"-function I get the error message Error: cannot allocate vector of size 224295 Kb As I understand it, the default is that there is no memory-limit in R other than machine resources, but somehow R does not get acces to the 24...

...with ocfs2 1.2.9, the new servers have ocfs2 1.4.3 installed. Part of the refresh process is to run fsck.ocfs2 on the volume to recover, but right now as I am trying to run it on our 700GB volume it shows a virtual memory size of 21.9GB, resident of 10GB and it is killing the machine with swapping (24GB physical memory). Can anyone enlighten what is going on? Ulf.

Hello, Im about to migrate a 6Tb database from Veritas Volume Manager to ZFS, I want to set arc_max parameter so ZFS cant use all my system''s memory, but i dont know how much i should set, do you think 24Gb will be enough for a 6Tb database? obviously the more the better but i cant set too much memory. Have someone implemented succesfully something similar? We ran some test and the usage of memory was as follow: (With Arc_max at 30Gb) Kernel = 18Gb ZFS DATA = 55Gb Anon = 90Gb Page Cache = 10Gb Free...

...U; - hot swap for disks. We are looking for a solution in which we would be able to deploy a basic server with for example 2 SATA disks, 8GB of RAM, 1 NIC, 4 cors and to be able to use the same enclosure and motherboard and extend it to deploy a more heavy-duty server with for example 6 SATA disks, 24GB of RAM, 2 NICs, 8 cors. Which manufacturer can you recommend and why? We are looking for something rather not expensive but reliable which has a good support. All servers will be based on CentOS5/6 :) Best regards, Rafal Radecki.

Dear all I have a Windows Server 2008 R2 Enterprise machine, with 64bit R installed running on 2 x Quad-core Intel Xeon 5500 processor with 24GB DDR3 1066 Mhz RAM. I am seeking to analyse very large data sets (perhaps as much as 10GB), without the addtional coding overhead of a package such as bigmemory(). My question is this - if we were to increase the RAM on the machine to (say) 128GB, would this become a possibility? I have read...

...online for help increasing my R code more efficiently for almost a whole day, however, there is no solution to my case. So if anyone could give any clue to solve my problem, I would be very appreciate for you help. Thanks in advance. Here is my issue: My desktop is with i7-950 Quad-core CPU with 24Gb memory, and a NVIDIA GTX 480 graphic card, and I am using a 64-bit version of R under 64-bit Windows . I am running a "for" loop to generate a 461*5 matrix data, which is coming from the coefficients of 5 models. The loop would produce 5 values one time, and it will run 461 times in to...

...unt is greater than 2^31. For example: > xx <- runif(3e9) > sum(xx < 0.9) [1] NA Warning message: In sum(xx < 0.9) : integer overflow - use sum(as.numeric(.)) This already takes a long time and doing sum(as.numeric(.)) would take even longer and require allocation of 24Gb of memory just to store an intermediate numeric vector made of 0s and 1s. Plus, having to do sum(as.numeric(.)) every time I need to count things is not convenient and is easy to forget. It seems that sum() on a logical vector could be modified to return the count as a double when it cannot be rep...

...in vode(y, times, func, parms, ...) : cannot allocate memory block of size 137438953456.0 Gb In addition: Warning message: In vode(y, times, func, parms, ...) : NAs introduced by coercion This appears to be case regardless of the computer I use; that is, whether it's a laptop or server with 24Gb of RAM. Why is ode() trying to allocate 137 billion gigabytes of memory?! (I receive exactly the same error message whether I have, for example, 34000 or 80000 state variables: the amount of memory trying to be allocated is exactly the same.) I have included a trivial example below that uses a func...

...9;ve made some SAP benchmarks on my Xen system and discovered a huge difference in the performance of a "xened" SAP system compared to a native SAP system. Hence, I tried to figure out what might cause this 'overhead' and run a xentrace (listining to all events). Xentrace produced 24gb data and I converted it to 27gb human-readable data. After I gathered the human-readable data, I filtered the data and counted the appearance of each event. So far, so good. Now it comes: although I used paravirt-guests, the xentrace-tool reported HVM events in the trace data. Moreover, from my po...

...I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers). If others are using the director on larger setups maybe we can all post when things do or dont work well. Now to see if the solution is better than the problem :) Cor

...y double checked my rights and found them to be correct, then I restarted mysqld and this has fixed it for now. Has anyone else run into this problem? I am concerned that it will happen again if the actual cause is not corrected. I am running the latest Fedora on new quad core Dell hardware with 24GB RAM and 1.7TB of disk. Any help and/or suggestions much appreciated. Thanks. Nick -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I

Hi All, I have recently installed CentOS 6.3 with QEMU+KVM for Virtualization. I have successfully created a Windows 2003 VM with 4GB of RAM. The host server is an HP ML350 G8 with 24GB RAM and 24 cores. Details of one of the cores is shown below: processor : 23 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz stepping : 7 cpu MHz : 1200.000 cache size : 15360 KB physical...

Hi All, I'm wanting to convert a ragged list of values into a structured matrix for further analysis later on, i have a solution to this problem (below) but i'm dealing with datasets upto 1GB in size, (i have 24GB of memory so can load it) but it takes a LONG time to run the code on a large dataset. I was wondering if anyone had any tips or tricks that may make this run faster? Below is some sample code of what ive been doing, (in the full version i use snowfall to spread the work via sfSapply) bhvs <-...

Good day. We trying to test XCP cloud under some product-like load (4 hosts, each with 24Gb mem and 8 cores) But with just about 30-40 virtual machines I got an extreme load on dom0 on pool master host: LA is about 3.5-6, and most time are used by xapi and stunnel processes. It''s really bother me: what happens on higher load with few thousands of VMs with about 10-16 hosts in p...

...max = 0t1070318720 . . . "size" is at 3GB, with c_max at 1GB. What gives? I''m looking at the code now, but was under the impression c_max would limit ARC growth. Granted, it''s not a factor of 10, and it''s certainly much better than the out-of-the-box growth to 24GB (this is a 32GB x4500), so clearly ARC growth is being limited, but it still grew to 3X c_max. Thanks, /jim

I have a Pentium 4 machine that does not boot from my 32GB SanDisk Cruzer. Its first partition is 24GB and FAT32, to serve as cross-platform storage. There is a second partition of 7GB in EXT2 which is bootable and contains a Linux system armed with syslinux (extlinux). This works fine booting off of recent laptops and desktops alike. This particular desktop has in its BIOS everything related to US...
