pvmove speed
Are there any ways to improve/manage the speed of pvmove? Man doesn't show any documented switches for priority scheduling. Iostat shows the system way underutilized even though the lv whose pe's are being migrated is continuously being written (slowly) to. Thanks! jlc

disk partitioning - I'm missing something simple, I think
Hi all, Excuse the question as I'm sure those more experienced will find it simple. I've a CentOS5.1 box with six physical drives, two of which are used for nightly rsync backups. Contents of /etc/mtab, /etc/fstab, df and a brief narrative follow: ====================================================== # cat ./fstab /dev/VolGroup00/LogVol00 / ext3 defaults

Floating point precision / guard digits? (PR#13771)
...# integers, no problem > 1+1+1==3 [1] TRUE # binary floating point approximation underflows > .1+.1+.1==.3 [1] FALSE > .1+.1+.1==.3 [1] FALSE # binary floating point exact for certain numbers > .1+.1==.2 [1] TRUE I know that safe code should not test for quality of floats. Still, is R underutilizing the power of the underlying hardware? Grateful for comments, David.

PRI span problem - no D channel
Hi, I have the following happen to me after the restart of one of my servers: out of my 3 PRIs (all configured with the same technical settings), the last one isn't coming back. It's underutilized (chances it didn't get a call since my reboot), if it makes a difference . The PRI goes from provisioned to unprovisioned, and I get this regularly: [Jun 22 09:03:48]

FAX over PRI
We are doing this with the latest spandsp, iaxmodem and hylafax.

A couple metrics of LLD/ELF's performance
These numbers were collected on Rafael's clang-fsds test case (however, I removed -O3 and --gc-sections) with a command like: ``` sudo perf record --event=cache-misses --call-graph=dwarf -- /home/sean/pg/llvm/release/bin/ld.lld @response.txt -o /tmp/t --no-threads ``` And then ``` sudo perf report --no-children --sort dso,srcfile ``` One annoying thing about these numbers from perf is that

poor IO perfomance
Здравствуйте, xen-users. Just test domU IO perfomance: sda1 configure via phy:/dev/sdb1. Benchmark with dbench (dbench -D /usr/src -s 10 -t 120) - 102 Mb/s Native sistem (mount /dev/sdb1 /mnt && dbench -D /mnt -s 10 -t 120) - 140 Mb/s How i can speedup dbench? -- С уважением, Vitaliy mailto:vitaliy.okulov@gmail.com

# devices in raidz.
for s10u2, documentation recommends 3 to 9 devices in raidz. what is the basis for this recommendation? i assume it is performance and not failure resilience, but i am just guessing... [i know, recommendation was intended for people who know their raid cold, so it needed no further explanation] thanks... oz -- ozan s. yigit | oz at somanetworks.com | 416 977 1414 x 1540 I have a hard time

Problem with Memory Throughput Difference between Two Nodes(sockets)
Hi all, I installed xen4.0.1-rc3 & 2.6.18.8 (dom0) on my machine (INTEL Xeon X5650, Westemere, 12cores, 6cores per socket, 2sockets, 12MB L3,.. ) I figured out after running SPECCPU 2006 Libquantum benchmark that two nodes have different throughput. I set up 6vm on each node, and ran the workload in each VM. VM in node1 got 1500sec exec time while VM in node2 got 1990sec

Is asterisks the best for a simple DTMF response system?
I received a recommendation to check out Asterisk, as a platform to host a simple DTMF response system, something like: Setup up VoIP endpoint on Linux/FreeBSD system Answer incoming VoIP phone calls User enters 100#, perl script plays back "foo" User enters 101#, perl script plays back "fum" User enters 102#, perl script looks up something in

Meetme delay - normal?
Hi, I`ve done a few tests with comparing a two personne conf call (both phones next to each other) and a simple call from one phone to the other. In the simple call, there is virtually no delay when I am speaking. In the meetme call, on an underutilized server, with a transcoder card for G729, with one two participants, I have a relatively large delay (1/3 of a sec maybe?). There is an

Running R on dual/quad Opteron machines
Dear all, I am managing a departmental purchase of an Opteron based workstation/server for scientific computing on which we will be running R. The environment will probably be either Unix/Linux or Solaris and the amount of RAM will be 8-16Gb, depending on the number of processors. My main concerns are the following: 1. How much does R benefit from passing from one processor to two/four

Effects of migration
So, to follow up to my previous thread, we just successfully migrated our NFS-based mail cluster from qmail pop, courier imap, and bincimap to dovecot 1.1rc1. Overall the transition was very smooth, the only unexpected adjustment was having to implement ntpd on each box, rather than doing an hourly ntpdate against our local ntpd server, to prevent dovecot from crashing itself from too much

[RFC] Transcendent Memory ("tmem"): a new approach to physical memory management
At last year''s Xen North America Summit in Boston, I gave a talk about memory overcommitment in Xen. I showed that the basic mechanisms for moving memory between domains were already present in Xen and that, with a few scripts, it was possible to roughly load-balance memory between domains. During this effort, I discovered that "ballooning" had a lot of weaknesses, even though

Help setting 2 Offices in US and India
I am new to Asterisk and VoIP. I have been given the task of setting up a telephone network in US and India. When customers call the US location, the calls should route to India (using VoIP) and handle there. The Indian location should be able to call Us numbers using the Voip to save money. The solution should be flexible enough to support initial of 5 simultaneous calls with the option to

Preferred mock framework
Hi In light of the fact that RSpec mocks are going into maintenance mode in the near future, I was wondering what everyone was switching to. I liked the look of FlexMock most, so gave that a shot. However, there''s a few things that don''t work well with RSpec due to the traditional differences in the way Test::Unit cases are written vs RSpec specs. (One spec per
