similar to: Problem running Gluterfs over Infiniband

It seems the problems running mthca in a Xen domU have uncovered a bug in mthca: mthca uses dma_sync_single in mthca_arbel_write_mtt_seg() and mthca_arbel_map_phys_fmr() to sync the MTTs that get written. However, Documentation/DMA-API.txt says: void dma_sync_single(struct device *dev, dma_addr_t dma_handle, size_t size, enum dma_data_direction direction) synchronise a single

i'm attempting to rebuild centos51 kernel-xen. (fwiw, because pciback has NOT been compiled into the kernel, http://bugs.centos.org/view.php?id=2767) after, yum install kernel-devel kernel-xen-devel and usual, ln -s /usr/src/kernels/`uname -r`-`uname -m` /usr/src/linux cd /usr/src/linux cp /boot/config-`uname -r` ./.config make oldconfig make menuconfig ... next, make rpm

Hi Lamia, Currently there is no direct InfiniBand access support in the Official Xen trees. You might want to have a look at our Xen-IB implementation. A preliminary version can be downloaded here: http://xenbits.xensource.com/ext/xen-smartio.hg Some information about its design and applications can be found here: High Performance VMM-Bypass I/O in Virtual Machines (Usenix 06), and A Case for

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below. I can upload 2 crash dumps, if this is useful. For some reason the port doesn't become ACTIVE, so no packets arrive, but that is probably unrelated. % uname -a FreeBSD cosel.inf.tu-dresden.de

My problem is that the .td and .h files are not shown as sources in the codeblocks (.cbp) output generated by cmake. I’m consuming the .cbp file with Qt Creator - it’s seems to be an otherwise excellent tool for llvm development. It seems that the culprit is llvm_process_sources function in cmake/modules/LLVMProcessSources.cmake. The addition of .td sources and header files is wrapped in the

Hi, all, Is the Xen currently compatible with the InfiniBand? I found some information about the Smart I/O module, but it was posted in 2006. Is the module still maintained? Or, are there any up-to-date alternatives for that? Many thanks, Chiu _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello folks, I am running Xen 2.6 under Centos 5.2 installation, and am trying to port Xen migration abilities to Infiniband. But, the InfiniBand drivers do not work under Xen kernel, only under non-Xen kernels. It looks like I need to install some patches to rectify the situation. Has anyone ever worked with Infiniband and Xen and would be able to give me inputs about the same? I would really

Hello, I going to try to install OFED 1.4 on Xen 3.3 and I`d like to realize a VMM kernel bypass. Thanks to it my doomU will be able to communicate directly with my HCA and not pass by the dom 0. How can I realize that ? Is there a soft or something like that to do the kernel by pass ? I saw that it exist things like XEN-IB driver and SoftIB, there can i get it ? Or is VMM kernel bypass

Hello Folks, Yesterday while messing around with procmail for SpamAssassin I had my IMAP client open and it lost it's ability to see my Inbox except for two messages. I tried another IMAP client and no success. I can see all other directories such as sent and the ones I have made. The mbox file is there and catable/grepable. I even made a new one. I can read a test account Inbox from

Hi all, I''m getting my feet wet in the infiniband lake and of course I run into some problems. It would seem I got the compilation part of sles11 kernel 2.6.27 + Lustre 1.8.3 + ofed 1.4.2 right, because it allows me to see and use the infiniband fabric, and because ko2iblnd loads without any complaints. In /etc/modprobe.d/lustre (this is a Debian system, hence this subdir of

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

I would like to gain some idea of the XCP impact of these two CPU versions: Intel Core i7-2600, 3.4 GHz Core i7-2600K, 3.5 GHz Both have VT-x Differences 2600K does not include: Embedded Opions Available vPro Technology Virtualization Technology for Directed I/O Trusted Execution Technology Is the difference critical?

Hi, I've run into a veird problem. I'm using a B400P BRI and an A1200P card with dahdi (2.2.1) driver. The dahdi_scan shows the each moduls and spans, everything seems fine. With dahdi_genconf I made the config, set up the channels in chan_dahdi.conf, but after reboot, the two card changes the order, (originaly the B400P is the first (closer to the processor) and A1200P is the

Hello All, Some people thought about a n LLVM wiki. Is there some alreadly? I wish it would be linked from LLVM.org site. Here are a few questions which I would like to be answered (preferably on a Wiki, to possibly participate): assuming that LLVM (latest from CVS) was configure-d with ./configure '--ENABLE-TARGETS=HOST-ONLY' '--WITH-GNU-LD' My main (currently platonic - ie
