Release v2.7.0 with new features and bug fixes

This release contains quite a lot of new functionality, and refactored untied task support. Here's a
list of the new features included in this release:

• Updated Kokkos autotuning support, with new search strategies genetic_search, nelder_mead, and automatic. The complete list is exhaustive, random, simulated_annealing, genetic_search, nelder_mead an
  d automatic.
• Nested Kokkos autotuning support allows for complicated search strategies when doing nested Kokkos
  search contexts. For example, choose between two execution policies, while autotuning the internals of each.
• NVTX pass-through support allows APEX timers to be fed to NVIDIA performance tools if desired.
• dladdr support for symbol name resolution when binutils are not available.
• Robust tracking of pthreads without needing to wrap all pthread functions.
• Added support for the TaskStubs library, a "PerfStubs" like library for instrumenting task based r
  untimes like Iris, PaRSEC, and StarPU. This support includes new events for scheduling, data transfe
  r as well as execution. Task arguments are included in the Google Trace Events output.
• Added support for complicated MxN parent-child task dependencies, not just 1xN. This provides comp
  lete support for the above runtimes.
• All runtimes are treated as untied tasks, even standard callpath timer stacks. This allows for com
  plicated task dependency graphs combining asynchronous tasks and callpath timer stacks.
• Enabled measurement of HIP, CUDA, and SYCL in the same executable for Iris support. Will also support OpenCL (Intel) if needed.
• Added OpenCL support for Iris on Intel GPUs/FPGAs.
• Added Python support with updated PerfStubs.

Complete list of commits in this release:

view commit • Updating kokkos to 4.2.01

view commit • Re-enabling kokkos allocation tracking When enabled, APEX will keep track of allocations through Kokkos and ensure they are all freed before exit

view commit • Trying to clean up memory allocation tracking When tracking allocations on the host, everything seems to be working correctly but on occasion, we see allocation amounts changing on the stack in gdb on frontier. can't explain it yet. But some fixes are included in this commit.

view commit • Updating roofline stats to use new CSV output

view commit • Adding NVTX pass-through support. As requested for the pika project, the ablity to pass APEX timers through to NVTX. This is not compatible with APEX cuda support, since it implements the NVTX API. However, it should work with an applicaiton linked with APEX if the APEX_ENABLE_NVTX_HANDOFF environment variable is set.

view commit • Merge branch 'develop' of git.nic.uoregon.edu:/gitroot/xpress-apex into develop

view commit • Fixing errors in unit tests on apple

view commit • Removing debug print message

view commit • Fixing builds with and without kokkos. If APEX is configured without Kokkos it should build now. And APEX will build examples correctly with kokkos, and will build Kokkos only if the Kokkos examples/tests are requested. Otherwise it just uses the headers.

view commit • Fixing .dylib/.so for apple configurations

view commit • Forgot to update an enum name for CUDA

view commit • Adding OpenMP library when linking against Kokkos unit test with OpenMP back end.

view commit • A few updates to help with periodic sampling of ROCM metrics on Frontier.

view commit • Added env var for specifying libnvToolsExt.so When using APEX as an NVTX pass-through using the APEX_ENABLE_NVTX_HANDOFF variable, NVIDIA doesn't automatically load the library with nvtx support. Adding APEX_NVTX_LIBRARY which defaults to "libnvToolsExt.so" but can be overridden with a full path, or you can add the path to LD_LIBRARY_PATH.

view commit • Merge branch 'develop' of git.nic.uoregon.edu:/gitroot/xpress-apex into develop

view commit • Changing from backtrace_symbols to dladdr to resolve addresses when BFD is not available.

view commit • Removing sleep during shutdown if the background thread is already done.

view commit • Removing sleeps from unit tests, exit should be clean now even for very short programs.

view commit • Changing NVTX pass-through to use different colors for up to 25 different timers.

view commit • Adding first version of genetic search algorithm based on random

view commit • Fixing osx build errors

view commit • First genetic search implementation.

view commit • Debugging genetic search

view commit • Debugging autotuning of kokkos kernels - problems with genetic search and nested contexts should now be working.

view commit • Fixing cached variable usage When using cached tunings from Kokkos, the variables might not be declared or provided in the same order, and depending on the execution may not be given at all. So...ignore the IDs other than for mapping from the old context to the old variables, or the new contexts to the new variables. We now match the variable names between context hashes, which should be correct in the future.

view commit • Enhancing autotuning search with nested contexts. When doing autotuning with Kokkos kernels, it is possible to have nested search contexts. When that happens, we want to make sure that we explore all branches of all possible scenarios. For example, the "idk_jmm" test in the https://github.com/khuck/apex-kokkos-tuning repository has one context to choose between a team policy and a mdrange policy, and each of those has tunable parameters. Because the outer context has only two choices, it can converge very quickly unless we prevent it from converging until the search has completed for both team and mdrange policy implementations. That's what this change does - if we have nested search contexts, the outer context(s) won't converge until the inner context searches converge. I also reduced the max_iterations limit for random, genetic_search and simulated_annealing to 500 from 1000.

view commit • Fixing output for exhaustive tuning

view commit • Fixing output for tuning strategies to be more helpful.

view commit • debugging simulated annealing with one variable of only a few values.

view commit • Minor changes to fix thread tracing When threads are created before main (looking at you, CUDA), or are not terminated before main terminates (looking at you, Iris), we need to make sure that the registered new threads have a thread ID. To do that, the top level timers for those threads should have synchronous start/stop events, otherwise they get a single "unified" event at the end with the thread ID belonging to the main thread (because it is the one cleaning up a the end).

Release v2.6.5 with bug fixes

view commit • Cleaning up kokkos tuning verbosity, shortening simulated annealing minimum iterations.

view commit • Adding common tree construction at end of MPI execution. This will speed up analysis with python and the apex-treesummary.py script.

APEX Version 2.6.2

Several change to the APEX code structure, including separation of HIP, CUDA, OMPT, LEVEL0, PERFETTO and MPI support to separate libraries. This allows us to have one configure/build on a system, and allow it to dynamically add support at runtime to support different features. This allows us to have a configuration that provides support for CUDA but doesn't require it, for example. Other new features include:

• Level0 (SYCL/OneAPI support)
• Improved OMPT support for supported compilers
• Phiprof support (VLASIATOR)
• StarPU support
• Perfetto native tracing support (doesn't yet support flow events, JSON trace output still recommended)
• Merged CSV output for both flat profile and task tree data
• Python scripts (apex-summary.py, apex-treesummary.py) to post-process merged CSV output
• Many bug fixes

view commit • Initial Level 0 support. Profiling works, but tracing timestamps are quite bogus.

view commit • Updating OneAPI support, still examining timestamps

view commit • Fixing APPLE pedantic build issues.

view commit • Adding native perfetto tracing support, very rudimentary support.

view commit • Working with correct timestamps now

view commit • Lots of fixes for starpu and pthreads. All detached threads are now correctly handled at exit, and starpu counters are back.

view commit • Debugging missing stop/starts from threads that are spawned by blas, cuda, starpu, etc.

view commit • Fixing pthread_create wrapper support for library threads launched before main. Also changing order that timers are written to taskgraph.0.dot, becuase when APEX MAIN, apex_preload_main, and APEX pthread wrapper timers aren't written first, they get lost in the graph. we want the graph anchored at those timers.

view commit • Timer throttling is now a runtime option, disabled by default.

view commit • Phiprof support

view commit • Adding timer throttle options to apex_exec

view commit • Renamed config file, removed a compilation message

view commit • Merge branch 'develop' into oneapi

view commit • Adding general metrics for tasktree nodes!

view commit • Removing debug message

view commit • Adding ability to check whether MPI can accomodate the memory requested for big transfers. Use the APEX_VALIDATE_MPI_MEMORY_USAGE variable to enable it.

v2.5.1

view commit • The HPX configuration was missing ROCPROFILER

view commit • Adding ROC profiler sources for HPX when HIP support is requested

view commit • Cleaning up HIP enabled builds with GCC as compiler

view commit • Merge branch 'develop' of git.nic.uoregon.edu:/gitroot/xpress-apex into develop

view commit • Fixing apparently broken Range Begin/End Push/Pop Cupti hasn't been making callbacks for range end or pop. So we will wrap those functions, instead of processing callbacks

view commit • Starting fix on range end events

view commit • Merge branch 'develop' of git.nic.uoregon.edu:/gitroot/xpress-apex into develop

view commit • Updating version number

APEX Version 2.5.0

view commit • Trying to integrate OpenMP target offload for AMD and NVIDIA

view commit • Adding clock synchronization code, but not enabled yet.

view commit • Working MPI clock sync for OTF2. Still need to test and fully implment the HPX version. In this implementation, all ranks determine a latency between rank 0 and themselves, then compute a clock drift between the two. That drift is added to the archive file creation time as an absolute reference that all ranks can use.

view commit • Updating HPX version of clock sync before test with HPX build

view commit • Updated clock sync for OTF2 trace output for HPX. This doesn't actually do a clock sync, but uses the OTF2 archive creation time as the "baseline" timestamp for all localities. Unfortunately, I need to figure out a safe time to make lco requests from one rank to another - during the apex::initialize phase, HPX isn't quite ready to handle requests yet.

view commit • Fixing initial values for kokkos tuning search

view commit • Minor fix to prevent crash when resolving long Kokkos kernel names

view commit • Fixing initial value for interval set parameters. When tuning Kokkos kernels, we need to use the initial value of the variable, which is (supposed to be) given to us by Kokkos.

view commit • Cleaning up kokkos autotuning code

view commit • First commit for transferred/renamed repo

view commit • Allow for unlimited custom policies Needed for Kokkos autotuning, allow as many tuning sessions as the system requests. Also reduce the output to the screen.

view commit • Fixing stat structure for OSX

view commit • Adding delayed start and max measurement Adding APEX_START_DELAY_SECONDS option and APEX_MAX_DURATION_SECONDS to specify a delayed start of measurement, and a max length to measure. The max length does not include delayed time. So a delay of 1 seconds and a max length of 2 seconds would record seconds 1-3 of an execution.

view commit • hipcc doesn't defined the _OPENMP macro, so don't expect it.

view commit • Merge branch 'develop' of git.nic.uoregon.edu:/gitroot/xpress-apex into develop
