InfiniBand hardware support?Answered

Hi Wyatt,

Have you given thought to providing us with controls that might manage how a hardware fingerprint is established? I ask because TurboFloat isn't happy with my client's somewhat uncommon hardware configuration, but I think it could be, with a small nudge.

We would like to use floating licenses across several Linux systems connected together as a computational cluster. Here's the issue: these systems do not have Ethernet interfaces. They are instead networked using InfiniBand host adapters, a type of high-performance interconnect. At runtime the TurboFloat library fails to generate a hardware fingerprint from this device because the active IP network in "/proc/net/dev" is named ib0 instead of eth0 or en0, etc.

Their network is configured with an emulation layer for IP traffic called IP-over-InfiniBand (IPoIB), so the systems should be able to communicate with the floating license server just fine. The emulated IP device also has a standard MAC address. I feel that if I could just provide TurboFloat with a fallback list of network devices to query, the whole process would probably succeed. Would something like that be possible?

Thanks
