...gle directory and still get lookups at a rate of 5,000 files/sec. That leaves me wondering 2 things. How can we get 5,000 files/sec for anything and why is our performance dropping off so suddenly at after 20k files? Here is our setup: All IO servers are Dell PowerEdge 2950s. 2 8-core sockets with X5355 @ 2.66GHz and 16Gb of RAM. The data is on DDN S2A 9550s with 8+2 RAID configuration connected directly with 4Gb Fibre channel. They are running RHEL 4.5, Lustre 6.7.2-ddn3, kernel 2.6.18-128.7.1.el5.ddn1.l1.6.7.2.ddn3smp As a side note the users code is Parflow, developed at LLNL. The files are S...

...terms of live migration, there seems to be a problem when moving from a higher (in terms of CPU MHz) to lower (MHz) system -- even if the higher of the two is a much older CPU model. For example, I can reproduce the bug under Xen 3.4.3 with the following: * Migrating from X5450 @ 3.00GHz to X5355 @ 2.66GHz fails, but the opposite (increasing in CPU frequency) succeeds. * Migrating from Xeon(TM) CPU 2.80GHz to E5310 @ 1.60GHz fails, but the opposite (increasing in CPU frequency) succeeds. BTW, when I say "fails", what I really mean is the migration succeeds but the domU is n...

...nt in time. The patch was generated against Xen 3.3.0 but will cleanly apply to both xen-3.3-testing and xen-unstable. It has only been tested on x86_32 but the ia64 portion of it should (hopefully) be obvious. Note that I needed to backport the patch from [1] to get samples on my processor (Xeon X5355) but, as the patch doesn''t seem to have gone into mainline yet [2], I am holding off on submitting it here.

Tearing our hair out on this one. Trying to install CentOS 5 x86_64 on a Supermicro X7DVL-E with 2 Xeon L5320 quad core CPUs, 3Ware SATA RAID controller in a mirrored setup and 4 GB of memory. Installation crashes at random places while copying the files. We've run memtest86 for 24 hours without any errors, replaced the RAID controller, motherboard and disks, but still no luck.

I ran the tests for the latest snapshot (openssh-SNAP-20130307.tar.gz), and all tests reported passed. Full results can be sent, but the zip I originally tried was blocked. My system: Linux rigel 2.6.38-gentoo-r6 #1 SMP Sat Jun 25 13:48:28 CDT 2011 x86_64 Intel(R) Xeon(R) CPU X5355 @ 2.66GHz GenuineIntel GNU/Linux Andy Clements

...e when doing I/O to a disk images contained in single files from a paravirtualized domain and from an HVM at the same time. The problem was found in a Xen box with Fedora 8 x86_64 binaries installed (Xen 3.1.0 + dom0 Linux 2.6.21). The test hardware was a rack mounted server with two 2.66 Ghz Xeon X5355 (4 cores each one, 128 Kb L1 cache and 8 Mb L2 cache), 4Gb of RAM and one disk of 250 Gb. Both paravirt and HVM domains have 512 Mb of RAM and 8 vcpu''s and runs also a Fedora 8 x86_64 distro. Stressing at the same time the paravirtualized and HVM guests with disk stressing tools like ...

I've just added a PREVIEW release of my upcoming how-to guide for Asterisk PBX on EC2. It is based on months of testing and evaluating Asterisk on EC2. It addresses all kinks and showstoppers that many people have experienced over the past year or so. Because this is a preview, it is not the final version of this guide. It is subject to change (format, copy, layout, etc.) To view and download

Hi! Anyone have a suggestion which version of Linux would be the best host? We typically use Ubuntu but we are flexible since we want the best performance and the least amount of headaches getting it installed and working.
