prov/util: Add brk intercepts and add missed symbol #13

  • Add missed symbol in FI_DBG
  • Add brk intercepts: We need to define if we use CURBRK - ompi says - I think, we shouldn't use this because we are for glibc only.

TODO: How should we initialize new_addr = sbrk (0); ?

Hpcs (high performance connection scaling) is a unit test framework to
generate network traffic between an arbitrary number of nodes according
to some traffic pattern.

Hpcs depends on MPI for address exchange, node identity, and barriers;
therefore, it isn't compiled by default but may be enabled with:

	./configure --enable-hpcs MPICC=<mpi-path>/mpicc

This uses the AX_MPI macros (from the autoconf-archive
package).

Invocation Example:
fi_multinode -s <server_address> -n <N> where N is number of processes.

This test can be invoked by multiple processes across multiple nodes. Only one of those nodes would be able to bind to the server address and that would become the server and all others end up as clients, for out of band(OOB) communication.

All these processes initialize ofi on their side and create rdm endpoints. OOB server gathers the rdm endpoint addresses from all the clients and sends them the whole list i.e., allgather of addresses.

all processess use these addresses to add to av and start posting sends and recvs based on the given pattern.

Next Steps:
1) Support ipv6 addresses for OOB connections.
2) Support different multi node patterns to test
3) Add tests for tagged, rma & atomics

Doesn't this set old and new address to the same value?

@shefty actually, yes. i left it temporarily. We need to find the new_addr like that: here

@shefty Could we set new_addr = brkaddr?

I would copy the OMPI implementation. I skipped it when adding the other hooks because I didn't think it was worth it. But it sounds like it is needed still.

@shefty Tried to do the same. The OMPI implementation without _CURBRK, I guess.

A separate pipeline will be used for creating and publishing builds.
This commit removes this logic from the build verification pipeline.

EFA's fi_cancel() implementation was not handling multi recv buffers correctly
and was leaking rx entries. It still does not search for messages in flight
which will need to be addressed in a follow up commit.
