Changelog v1.7.6

Change log for LCI v1.7.6

Major Changes

• Split the original C library, LCI, into two libraries: a C library, LCI, and a C++ library, LCT (Lightweight Communication Tools).
  • LCT provides basic tools that can be used across libraries, including
    • timing
    • string searching and manipulation
    • query thread ID and number
    • logging
    • performance counters
    • different implementation of queues
    • PMI (Process Management Interface) wrappers
  • The CMake variable LCI_WITH_LCT_ONLY can be used to enable LCT-only build.
• Add(LCI_cq_createx): be able to specify the cq max length.
  • This is a temporary workaround for multiple devices.
• Add(LCI_ENABLE_PRG_NET_ENDPOINT): control whether to use the progress-specific network endpoint

Breaking Changes

• The lib output name is changed from LCI/LCT to lci/lct.
• Change LCI_IBV_ENABLE_TRY_LOCK_QP to LCI_IBV_ENABLE_TD and make it an env var.

Other Changes

• Change the default endpoint number from 8 to 1024.
• Change the CircleCI config to Debug build; Enable performance counter in debug CI.
• Merge lcii_config.h.in into lci_config.h.in.
• Improve(pcounter): do not call LCT_now when the performance counters are not enabled.
• lci-ucx rcache: turn off assertion by default

Fixed Issues

• Fix liblci.pc.in.
• Fix the ibv backend with old libibverbs that does not support odp.
