WebFor example, you can use the omp target directive to define a target region, which is a block of computation that operates within a distinct data environment and is intended to be offloaded onto a parallel computation device during execution. For more information about the OpenMP directives, see Pragma directives for parallel processing.. You can also use … Web13 de fev. de 2024 · 1 I'm using OpenMP target offloading do offload some nested loops to the gpu. I'm using the nowait to tun it asynchronous. This makes it a task. With the same input values the result differs from the one when not offloading (e.g. cpu: sum=0.99, offloading sum=0.5). When removing the nowait clause it works just fine.
