That's a remote invalid request error. Were you testing
with RDMA or without?
We were using the version that runs over IB.
Well, yes. But you can do that with ordinary SENDs, or you
can enable RDMA for large data blobs as well. But
Oh, and if you're using RDMA - does this happen to be with
qlogic HCAs? If so, I just received a patch from Ralph
Campbell with some fixes to the way we set up out DMA
mapping.
RDS in OFED 1.3 does not currently work on the QLogic HCAs

Some HW revisions of eHCA2 may cause an RC connection to break if they
received RDMA Reads over that connection before. This can be prevented by
assuring that, after the first RDMA Read, the QP receives a new RDMA Read
every few million link packets.

When I hit a RDMA error (which happens quite frequently now at rds-stress
exit, thanks to the fixed mr pool flushing :) I often see the RDS
shutdown_worker
getting stuck (and rmmod hangs). It's waiting for allocated WRs to disappear.
This usually works, as all WQ entries are flushed out. This

Roland, you said that XRC API is ugly, are you going to push it upstream
in its present form?
That's a good question. Since there is no 'present form' for XRC as
far as I can tell, it's hard to make a definitive answer.

Moving the QP to error state flushes all of the outstanding WRs and

If you want to delete all of the outstanding WRs, you should move the QP
state to reset.

Attached is the patch I sent to Olaf.
It basically exchanges calls like dma_map_sg() to ib_dma_map_sg()
so that the InfiniPath driver can intercept the DMA mapping
calls and use kernel virtual addresses instead of physical addresses.
The InfiniPath driver uses the host CPU to copy data in most

Well, I can't speak for everyone, but in my opinion if someone wants to run
MPI job so huge that XRC absolutely has to be used to be able to actually
finish it then he should seriously rethink his application design.
But where do you think the crossover is where XRC starts to help MPI?
