Summary0002944: modify the adaptive parallelisation algorithm
Descriptionthe current adaptive algorithm is based on heuristics which makes it hard to stabilize. This should be changed in such a way that the parallelization degree D is increased and decreased depending on the observed deviation S of the current operation completion time T with the observed average A of the previous n operation completion times:

if T >= (A + S) then
  D = D - 1;
endif

if T >= (A + 2S) then
  D = D / 2;
endif

if T <= (A - 2S) then
  D = D * 2;
endif

if T <= (A - S) then
  D = D + 1;
endif
TagsNo tags attached.
