2c3ddfd0c2 Merge branch 'ib-rearrange-qp' into develop
Closes #152. As described in #182, we will not rearrange the Queue Pairs
for connected mode. As soon as we test many-to-one connections for the
unrealiable connection, we will look again at this issue.

3acc3df7c4 ib_read() now works for UDP
Node is now able to send data in RDMA_PS_UDP mode. Right now it creates
a new rdma_cm_id for every connection request. We could/should do this
differently

1d6ee5aec8 Node can determine if data should be send inline
The user can set the maximum size of the inline data and the node checks
if a sample can be send inline. This commit doesn't contain a info
message to the user about what the final max inline size will be. (The
HCA will probably change the value set by the user.)

b1b778f542 Added buffer to ib_write()
Now, ib_write() reads every cycle cnt values from the Completion Queue.
If it is not able to return them to the framework immediately, it
temporarily saves them on a stack.

ib_write() checks every cycle if the stack is non-empty and if it is
possible to return values from the stack to the framework.

72e627b327 Fixes #166, all node interfaces are modified
The functions now look like this

int node_read(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);
int node_write(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);

This commit enables nodes to control how many samples will
be released by the framework through *release

746fd2f694 Refactored ib_write in the same way as ib_read (described in #153). Merged separate completion queue polls to ib_write. Closes #167 2018-07-08 15:00:47 +02:00

06e7434d6c Solved some state problems. This commit also solves #154, which was caused by a non-terminated thread. (This thread will be removed in a later commit anyway 2018-07-07 15:34:07 +02:00

836adee4d6 Node is able to clean everything up and reconnect. Node can abort if it is in STARTED and in CONNECTED state 2018-07-07 14:36:23 +02:00

e2061e58fc Events are now monitored in a separate thread. The segmentation faults we saw earlier were caused because we exited ib_start before we created a protection domain, which is used by memory_allocation 2018-07-07 12:49:22 +02:00
Dennis Potter
2bf122991c Started to convert the RDMA_CM_EVENT loop to a separate thread and added a new state to the node. This commit is still broken 2018-07-05 18:26:32 +02:00

5598f93582 Implemented disconnect function on source and target side. The cleanup function doesn't go through completely yet, probably because rdma_destroy_id blocks because not everything in the rdma_cm_id is destroyed yet. 2018-06-28 12:46:16 +02:00

a0f0410e73 This commit should be able to create a connection between two nodes.
This commit isn't checked for bugs and no memory management is done.
Furthermore, no poll threads are implemented.
