Generating and testing precompile statements for COSMO + Convex + MOI

Generating and testing precompile statements for COSMO + Convex + MOI

  1. I generated precompile statements via generate_precompiles.jl.
  2. Then I dev'd each of Convex, MOI, and COSMO, and added the precompile statements. (See the SnoopCompile docs).
  3. I removed the ProblemDepot specific precompiles from Convex, and added the SparseArray, Base (but minus the printing ones), and LinearAlgebra (minus isapprox) precompiles to Convex too
  4. Then I ran test_precompiles.jl, resulting in output.txt
  5. I ran it a second time, and saved the file as output2.txt.

E.g.,

include("generate_precompiles.jl")

# Now `dev` Convex, MOI, and COSMO, and add the precompile statements as above

include("test_precompiles.jl")

Effect on "first-solve" time

See output.txt and output2.txt for two runs of the timing test (which just solves one problem via readme_test). It seems just adding precompile statements to COSMO reduces the first-solve time by 15-25 seconds. Adding precompile statements to MOI and Convex reduces it by another 4-8 seconds.

Effect on precompilation time

Adding precompile statements will naturally increase precompilation time.

With the precompile statements, I get the following timings:
