Separate the ibv_post_send and ibv_poll_cq into different functions, so that these could be assigned to different LPF functions (e.g., trigger send early by moving ibv_post_send calls into IBVerbs:…

Extended LPF to expose lpf_get_rcvd_msg_count function. Also halfway (hopefully) through integrating BSC changes to enable both local and remote completion queues, which is key if we want to read t…

Very importantly, remove sleeps in the progress engine, as this leads us to notice new reads/writes too late.

Enable functionality to associate a received message with its memory slot. This is currently done via imm_data field which carries the memory slot ID of the destination at the sender before it is R…

Change IBVerbs::put to accept an original slot ID and the possibly modified slot ID if edge buffer is used. The original slot ID is then only used as a key for hashtable with key = slot ID and valu…

Main changes here: 1) Implemented a round-robin put-based allgatherv within LPF as I need it. 2) Add get_rcvd_msg_cnt_per_slot besides the more general get_rcvd_msg_cnt, as the counts should be per…

The attributes retry_cnt and rnr_retry were set to 6 and 0 for development. Now set to 7 / 7 for infinite polling, if needed.

Make lookup of message counters pure lookup, no polling. This is tricky for HiCR, which then needs to do sync explicitly before checking these counters.

Minor improvements - use ibv_destroy explicitly in shared_ptr reset call in a few missing cases. Also remove tryLock/tryUnlock in this version, as it is not used yet.

Improvements for atomic compare-and-swap operation. Among them, now call wait_completion. Wait_completion is extended now to return the ibv_wc_opcode list, to check if events are atomic compare-and…

Reorganize IBVerbs::get to register an Op::GET event. Sends are now basically either Op::SEND or Op::GET (put or get - both sends). Still lots of debug output
