Hi Sasha,
This patch supports a new option called --filterdownports. The option
will remove downports from the output if they were previously listed as
down in a cache.
This option is useful for clusters that have unpopulated switch ports.
Many system administrators look for the word Down in
Hi Sasha,
This patch supports additional lid and node description diffing options
in iblinkinfo. This is similar to the lid and nodescription --diffcheck
options in ibnetdiscover.

Change code like
x = expr(++x)
that assigns to x twice without a sequence point in between to the
intended (and well-defined)
x = expr(x + 1)

I am attempting to use NFS over RDMA (over infiniband), but there is some
problem. The NFS filesystem can be mounted on the client, and things
will work for some time (can read, modify, etc. the files over the mount),
but then (at a seemingly random time) the NFS server will dump these

The mlx4_core driver allocates 'nreq' msix vectors (and irqs),
where:
nreq = min_t(int, dev-caps.num_eqs - dev-caps.reserved_eqs,
num_possible_cpus() + 1);
ConnectX HCAs support 512 event queues (4 reserved). On a system
with enough processors, we get:
mlx4_core
Regarding the BW numbers: they look reasonable. You can try to improve the BW
up to 3.2GB/s by increasing PCIe MTU from 128 to 256 byte. It usually requires
BIOS configuration changes.
