Hi,
Could anyone confirm to me the maximum achievable bandwidth over a single 4xQDR
IB link into a OSS node. I have many clients doing a write test over IB and
want to know the maximum bandwidth we can expect to see for each OSS node. For
MPI over these links we see between 3 and 3.5BG/s but
DAPL is a high-performance interface that uses a small shim to provide a
common DMA API on top of (in this case) the IB verbs layer. In general,
there is a very small performance impact to be able to use the common
API, so you will not get more large-message bandwidth using native IB verbs.
I'
Hello Ashley, hello Kevin,
I really see no point to use disks to benchmark performance, when
lnet_selftest exists. Benchmark order should be:
- test how much the disks can provide
- test network with lnet_selftest
=> make sure lustre performance is not much below the
min(disks, lnet_selftes
Привет, Bernd!

I have just restarted server and now all OST devices works normally.
Can't explain this.
Thank you for your time and advice!
Best regards,
Katya

But it is that; it is just a particular type of storage cluster
system with a specific performance profile.
As to "expandable", consider again whether your requirements

Is it possible to compile Lustre as a module ?
AFAIK , it's not possible.
How do I compile Lustre with the latest Linux kernel ?
I went through the documentation on building from source
but It only talks about compiling with RHEL & SLES kernels
and not general kernels.
