UCT/API: Removed count and stride fields from uct_iov_t structure.

21

## What Removed count and stride fields from uct_iov_t structure. ## Why ? The fields are not used in current implementation.

## What Taken into account new endpoint configuration parameters for calculation of threshold of rendezvouz protocols in new protocol infrastructure. ## Why ? There are use cases with worse latency...

UCP/CORE: Fixed wiface activation counter.

1

## What Fixed counting wiface activation number. Removed increasing wiface activation count when the wiface is activated via protocol selection. Increased wiface activation count when the wiface is activated via...

GTEST/UCT: Do not query BAR1 memory using NVML under valgrind.

2

## What Removed querying BAR1 memory information using NVML API when running with valgrind. ## Why ? Workaround for the https://github.com/openucx/ucx/issues/9531 It seems that we may hang in nvmlnit under...

UCP/WIREUP: Removed obsolete condition.

1

## What Removed obsolete condition.

## What Removed `uct_md_rcache_overhead`. The method became unused after merging https://github.com/openucx/ucx/pull/8225. Added logic to use previously unused `UCX_RCACHE_OVERHEAD` environment variable. The variable can be used to configure the `rcache lookup`...

UCP/RMA: Do not flush UCT EP if UCT iface is not active.

3

## What Added condition to flush UCT endpoint only if corresponding UCT interface was activated. The condition is only relevant if new protocol infrastructure was enabled. ## Why ? Fixed...

UCS/SYS/TOPO: Added options to set distance between devices.

3

## What Added options to set estimated latency and bandwidth values according to the distance within the sysfs device tree. Moved platform specific values to `ucx.conf` file.

GTEST/COMMON: Added test for cuda async allocated buffers.

1

## What Extended UCP AM RNDV tests by adding buffers allocated by `cudaMallocAsync`.

UCM/CUDA: Added support for device-side variables.

3

## What Added hook for `cudaGetSymbolSize` to support device-side variables.
