similar to: problems running a vol over IPoIB, and qemu off it?

The problem described in the subject appears NOT to be the case. It's not that simultaneous reads and writes dramatically decrease perf, but that the type of /writes/ being done by this app (bedtools) kills performance. If this was a self-writ app or an infrequently used one, I wouldn't bother writing this up, but bedtools is a fairly popular genomics app and since many installations use

Is anyone running any Areca RAID controllers with the latest CentOS 7 kernel, 3.10.0-693.2.2.el7.x86_64? We recently updated (from 3.10.0-514.26.2.el7.x86_64), and we?ve started having lots of problems. To add to the confusion, there?s also a hardware problem (either with the controller or the backplane most likely) that we?re in the process of analyzing. Regardless, we have an ARC1883i, and

CentOS 7.4 client mounting a CentOS 7.4 server filesystem over nfs4. nfs seems to be much slower since the upgrade to 7.4, so I thought it might be nice to mount the directory as v4.0 rather than the new default of v4.1 to see if it makes a difference. The release notes state, without an example: "You can retain the original behavior by specifying 0 as the minor version" nfs(5)

It seems that lustre puts its modules in /lib/modules/2.6.16.21-0.8-default despite the fact that my kernel is 2.6.16.21-0.8-smp ! uname -a Linux n32 2.6.16.21-0.8-smp #4 SMP Sun Sep 24 08:47:30 BST 2006 i686 i686 i386 GNU/Linux make[3]: Nothing to be done for `install-exec-am''. /bin/sh ../../mkinstalldirs /lib/modules/2.6.16.21-0.8-default/kernel/fs/lustre /usr/bin/install -c -m 644

Hello, I have a problem with the srptools to connect my Dom0 to the scst over IB ressources. *When i''m on the Debian kernel (without Dom0) * root@blade1:/# ibsrpdm -c id_ext=003048ffff9dd3b4,ioc_guid=003048ffff9dd3b4,dgid=fe80000000000000003048ffff9dd3b5,pkey=ffff,service_id=003048ffff9dd3b4

We have a new install of CentOS 6.7 with infiniband support installed. We can see the card in hardware and we can see the mlx4 drivers loaded in the kernel but cannot see the card as an ethernet interface, using ifconfig -a. Can you recommend an install procedure to see this as an ethernet interface? Thanks On 05/25/2016 07:32 AM, Fabian Arrotin wrote: > On 25/05/16 03:08, Pat Haley

We seemed to have it a stumbling block when building with the above (supported) versions. Our process... 1. Start with stock rhel5 2.6.18-8.1.14 source tree 2. Configure InfiniBand support out of the the kernel (we will build OFED separately). 3. Apply the 1.6.4.2 kernel patches to the kernel source. 4. Build the kernel. 5. Build OFED 1.2 against the patched kernel 6. Build Lustre using

Hi We are trying to configure RDMA for an infiniband connection between our data server (running CentOS 6.8) and our compute nodes (running CentOS 6.6).? We have been trying to follow the instructions in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-configuring_the_base_rdma_subsystemedit however we are getting conflicting information on

Hi have what might be some elementary questions. Really, what I"d love would be for someone who has had good success to publish his/her configuration files and, maybe, the output from ifconfig. At this point, when I see the not-so-good performance I"m getting, I don't realistically know if I'm in the right ballfield. It seems to me, that with so many mellanox cards out

Hello, I have been playing with the XCP for a while now, and must say I''m very exited about the technology. I had no prior experience with Xen so it has taken me a while to understand the concepts, but now I feel most important issues are solved and I''ve purchased some hardware to build my (tiny) cloud on. The box is a Supermicro 1026TT-IBXF, so I have 2 x Ethernet and 1 x
