Linux – Infiniband on Linux

infinibandlinux

I will build computing cluster (about 64 nodes) and I'm looking for some informations. I want to connect them with Infiniband and install Linux. I tried to google it a little bit, but I couldn't find any informations how to set up a simple working configuration.

I want to use it to access NAS and for interprocess communication (MPI, etc.)

Is it easy to set up Infiniband on Linux? How to do it? Or maybe there is better solution?

The Infiniband itself is not a big deal to set up. You have to load the driver for your device and if you don't want to use anything else then IP the ipoib kernel module.

1 IP OVER INFINIBAND 2
3 The ib_ipoib driver is an implementation of the IP over InfiniBand 4 protocol as specified by RFC 4391 and 4392, issued by the IETF ipoib 5 working group. It is a "native" implementation in the sense of 6 setting the interface type to ARPHRD_INFINIBAND and the hardware 7 address length to 20 (earlier proprietary implementations 8 masqueraded to the kernel as ethernet interfaces).

After this you are able to use your device as a normal ethernet device.

Linux – Compiling and building Linux packages for multiple distributions / platforms

I highly recommend you look into the openSUSE Build Service. They've got all the various distros and architectures set up in Xen virtual servers, and they support a wide variety of packages, including RPM and DEB formats. It will save you loads of time and hassle setting up every one of those servers yourself, much less the time it'd take to get all of the includes and build-depends right.

Edit: As a side note, if you have security concerns, you can download the code and set up an OBS on one of your own servers instead of using the public ones.

Most ISP's block SMB traffic at their routers-so more than likely your clients won't be able to mount the share from outside the VPS providers network.

Configure these lines in smb.conf to setup a Samba share
