**Description** Linking the `tester` executable fails with `-lscalapack` missing on Frontier: ``` [ 83%] Linking CXX executable tester cd /ccs/home/jschuchart/src/slate/slate/build/test && /autofs/nccs-svm1_sw/frontier/spack-envs/base/opt/linux-sles15-x86_64/gcc-7.5.0/cmake-3.23.2-4r4mpiba7cwdw2hlakh5i7tchi64s3qd/bin/cmake -E cmake_link_script CMakeFiles/tester.dir/link.txt --verbose=1 /opt/cray/pe/craype/2.7.31/bin/CC CMakeFiles/tester.dir/matrix_params.cc.o CMakeFiles/tester.dir/matrix_utils.cc.o CMakeFiles/tester.dir/test.cc.o...

Linking fails with -lOpenGL not found

### Steps to reproduce On Frontier, load rocm/6.0.0 and try to build StarPU 1.4.7. ### Obtained behavior Linking fails with: ``` CCLD implicit_stencil ld.lld: error: unable to find library -lOpenCL...

Require C11

Error out if the compiler does not support C11 and limit the standard to C11 if the compiler accepts a standard flag. This limit prevents us from using features of...

Replace alignment_of_long_double with C11 alignof

This removes a static variable in a static function and uses C11 provides `alignof` instead to get a compile-time value. Also fixes this compiler warning: ``` opal_copy_functions_heterogeneous.c:495:1: warning: function declaration...

These checks have no relevance and cause problems in TTG because the input data pointers may change.

This is work I did for the SPMM benchmark in TTG. Problem is that many threads push active messages into the communication backend, getting stuck in MPI. The communication thread...

Provide mechanism to discard data

3

Add a function `parsec_data_discard` that releases the data such that the host copy remains intact but does not prevent destruction of the data once all device copies have been released....

Release function for parsec_object_t

## Description With https://github.com/ICLDisco/parsec/pull/694 the GPU task structure becomes a proper PaRSEC object and carefully avoid calling `PARSEC_OBJ_RELEASE` on it to avoid freeing it explicitly and instead add a callback...

Use red-black-tree in zone_malloc

1

Currently, zone_malloc iterates linearly over its blocks, leading to O(N) complexity and significant overhead if all blocks are taken. We now use a red-black-tree to order lists of free blocks...

## Description Currently there is a fixed mapping between data and data copies. Data copies cannot be used in multiple data. However, there can be instances where a data contains...
