Heterogeneous memory will be involved in several upcoming platforms on the way to
exascale. Combining technologies such as HBM, DRAM and/or NVDIMM allows to tackle
the needs of different applications in terms of bandwidth, latency or capacity. And new
memory interconnects such as CXL bring easy ways to attach these technologies to the
processors. High-performance computing developers must prepare their runtimes and
applications for these architectures, even before they are actually available. Hence, we …
