Hi, We are running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64 on a Quanta Cirrascale, up to date with patches. We have had a couple of instances in which the hard drives have become renamed after reboot (e.g. drive sda is renamed to sdc after reboot). One time this occurred when we rebooted following the installation of a 10GB NIC card, another time after we tried to install m...

Hi All, We looking for suggestions on dealing with mellanox drivers in CentOS 6.7 We tried installing mellanox drivers (MLNX_OFED_LINUX-3.2-2.0.0.0-rhel6.7-x86_64) on a Quanta Cirrascale server running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64. When we rebooted the machine after installing the drivers, it went into a kernel panic for every installed kernel except for Centos 6.7 2.6.32-573.22.1.el6.x86_64.debug. After we uninstalled the drivers, the machine failed to boot for a...

...s and even worse - may critically depend on using the full available GPU ram. (Large matrix sizes and soon big Fortran arrays or complex data types) Long term - direct PCIe copies between cards will be important.. aka zero-copy. It may seem crazy, but when you have 16+ GPU in a single workstation (Cirrascale) stuff like this is key.

Hello, I am currently looking into ways to support fixed virtual address allocations and sparse mappings in nouveau, as a step towards supporting CUDA. CUDA requires that the GPU virtual address for a given buffer match the CPU virtual address. Therefore, when mapping a CUDA buffer, we have to have a way of specifying a particular virtual address to map to (we would ask that the CPU virtual
