[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.
