Not an issue - just try to understand how the flush_job works

[riveridea]

Hi,

Usually SIMD need to get enough number of jobs to do parallel computing, but when if no enough jobs are in the SIMD lanes, how exactly the flush_job is doing? For example if the number SIMD lanes is 16 and I have 5 jobs to be flushed. Is the flush_job processing these 5 jobs one by one or can process the 5 jobs in parallel? In my understanding, the flush_job can use some padding tech to fill the rest 11 empty lanes to process the 5 real jobs in one shot. Is that right?

Thanks

Yes, flush_job will process all jobs in parallel by doing:

1. find a valid lane
2. copy required fields from valid lane to all empty lanes (e.g. in/out pointers, key pointers etc.)
3. process all lanes in parallel until first valid job completes
4. return completed job
