[feature] High-level block: Replicaset

See merge request !153

Remove scratchpads from library

See merge request !152

This building block needs a serious redesign, in part because areas, tilings, and dmas have changed so much. By the time we had iterators and allocators to the library, this building block will just need to be completely refactored.

[fix/ci] update excit for check-programs

See merge request !151

Excit was updated to include the extra rule to cross-compile check
binaries.

[fix/ci] ECP-CI needs absolute URLs

See merge request !150

gitlab likes relative urls for submodules, but since we're also using a
bunch of mirrors for ECP-CI, we can't use relative urls unless we also
mirror excit on those. Which is not planned right now.

[fix] remove unused scripts

See merge request !103

The run.sh script for benchmarks is not necessary anymore, and the
release.sh script is not used for releases either.

[feature] Add excit as submodule

See merge request !149

git now includes an option to clone submodules on the fly.

Make check directly after configure doesn't work reliably when using
subprojects.

Add excit library as submodule of AML, add make the necessary changes
across the autoconf/automake infrastructure.

Note that clang-format is not triggered by these changes.

[feature/fix] copy layouts internally for dmas

See merge request !148

If necessary, dma implementations copy the source and destination
layouts to avoid issues where the user would like to lose track of the
layout once the dma request has been launched.

Fixes #51.

Plain Sparse Layout

See merge request !141

Implementation of layouts for sparse memory areas.

[fix] missing doc/name fixes

See merge request !146

Missing commit from merge request !145.

[feature] duplicate operator for layouts

See merge request !145

Add a function to create a layout from an existing one. We call it
duplicate to avoid the confusion with dma copies.

- ownership consistent with destroy operator: underlying layouts are
  also copied
- data is copied by the implementation, and the generic code takes care of
  the ops pointer.

Now that we have unit tests in multiple directories, it's easier to just
change the ignore rules to match .log and .trs files across the entire
repo.

Add valgrind checks to the CI

See merge request !143

Verbose logs and one single OPENMP thread to avoid weird valgrind
scheduling issues.

Fix #68

Limit the size of the memory tested to avoid tricky overflows.

Detected by valgrind.

return-early test always succeeding for the wrong raison.

target_dims is not the same size as the dimensions of this layout.

Detected by valgrind, but without consequences.

nanosleep is not guaranteed to sleep under valgrind, which make our
async test code run forever. Change for a random amount of work in a
loop, that's somehow better.

Generic layout_destroy

See merge request !144

Refactor destroy API for layouts so that we can solve a long standing
ownership issue with complex layouts. Putting the destroy operator
inside the implementation-specific ops allows us to call a generic
destroyer on embedded layouts.

Note that this introduce a ownership policy for pad & reshape layouts
that take ownership of the targeted layout at creation time.

Related to #55.

ECP-CI Fixes for Theta

See merge request !142

Extra recursive target across the repository to build the test programs
without running them. Allows us to cross-compile both the lib and the
test programs on frontend systems, without launching on the
compute nodes.

Make us of that to fix the theta ECP-CI job using icc.

Some implementations require the file descriptor to be -1 when asking
for an anonymous mmap, making this test fail. The fix is to test both
anonymous mappings and file-backed mappings separately.

Some filesystems do not support the full posix range of file-backed
mmaps too (parallel file systems), so the file used for tests must be on
a simpler filesystem.

DMA Cuda

See merge request !140

Nicolas Denoyelle authored Jul 10, 2020 and Swann Perarnau committed Jul 10, 2020

Simple copy operator and dma engine for CUDA.
Requires cuda layouts to work.
