Thank Vanush,

I have read this presentation already; unfortunately, I found it rather hard to draw an overall picture of gnuradio scheduler to some extent of details. Perhaps, as Tom said on his webpage (http://www.trondeau.com/blog/2013/9/15/explaining-the-gnu-radio-scheduler.html) the scheduler is the most mysterious and complicated part of gnuradio - not easy to digest it

Could you please provide me with some relevant or supplement readings to that presentation? I would grateful for it.
My first intuitive question is that since each signal processing block does require both input and output buffers, then it may cause the source-sink latency to be significantly large. Is this true and is there any design analysis on this?

With best regards,

Nguyen Anh Duc

Dear all,

I wish to study how gnuradio handles the dataflow,e.g., buffering, scheduling, synchronization, optimization as well as resultant latency in detail. However, I can not find any material that explain such things clearly. Could you please point me to direct or indirect resources e.g., in literature which present I need. I would appreciate it much,

With best regards,
