Questions tagged [offloading]

This tag is for questions about software which utilize mechanisms for reducing workload from the CPU. This can be done by aggregating work before further processing is done and/or processing some of the workload in a dedicated hardware.

This tag is for questions about software which utilize mechanisms for reducing workload from the CPU. This can be done by aggregating work before further processing is done and/or processing some of the workload in a dedicated hardware.

Common offloads are network stack offloads such as LRO, GRO, TSO, etc. Other offloads are CPU offloads such as Intel's AES-NI for IPSec.

Offloads can be multi-layered, for example OVS (Open Virtual Switch) has a service for identifying and creating steering rules for packets. The user space service will offload the steering to the kernel software. Specific hardware can process the steering itself, so the kernel might offload to the hardware.

Common questions about offloads

  • How does specific offloads work?
  • How to enable offloads for specific cases?
  • What is the benefit of using specific offload?

Heterogeneous OpenMP parallel loop with Intel MIC offloading

I am working on a code which includes a loop with many iterations (~10^6-10^7) where an array (let's say, 'myresult') is being calculated via summation over lots of contributions. In Fortran 90 with OpenMP, this will look something like: !$omp…
