 # peak-perf

 - meassure ddr to ddr
 - meassure ddr to hbm
+
 All for 1KiB, 4KiB, 1MiB, 1GiB
+
 All for HW and also SW path
+
 All for intra-node, inter-node and inter-socket
+
 --> conclude how much overhead DSA engine has
+
 --> conclude size after which using HW makes sense
     this point is reached when submit overhead for
     hw execution is smaller than entire copy time
     for sw execution
+
 # submit // done
+
 - single submit-and-wait
 - multi submit
 - batch submit
+
 All with both 1 and 4 engines per WQ
+
 All for 1KiB, 4KiB, 1MiB, 1GiB
+
 All only on DDR and intra-node
+
 --> conclude which work submission strategy is best for which size
+
 --> conclude whether multiple engines significantly improve batch perf
+
 # mtsubmit // done
+
 - multiple threads submit to the same WQ
 - use 1,2,4,8,12 threads
+
 All using DDR and 1MiB
+
 All for 1 vs 4 engines
+
 All on DDR and intra-node
+
 --> conclude how bad mt submit hurts performance
+
 --> conclude whether multiple engines help mt submit
+
 # cross-copy // done
+
 - compare which is faster: xcopy, copy from source node, copy from dst node
+
 All for both inter-node and inter-socket copy using DDR and 1MiB on 4E
+
 --> conclude where a copy thread should live
