[VCL Cluster] Recommend budget Infiniband hardware?

[epixoip]

Any IB hardware will do. I picked up a bunch of 10 year old 4x SDR hardware off eBay for less than a grand. Topspin 120 switch plus some old Mellanox HCAs. You really can't go wrong.

As far as setting it up, it's pretty much plug and play.

Drop the following in /etc/modules:

Code:

ib_sa
ib_cm
ib_umad
ib_addr
ib_uverbs
ib_ipoib
ib_ipath
ib_qib

Add a configuration like this one to /etc/network/interfaces:

Code:

auto ib0
iface ib0 inet static
        address 192.168.1.5
        netmask 255.255.255.0
        post-up echo connected >`find /sys -name mode | grep ib0`
        post-up echo 65520 >`find /sys -name mtu | grep ib0`

And that's it.
