< jeffin143> Did you know about this ?
< jeffin143> scroll down a little bit : Fighting Padding Waste
< jeffin143> Do you think alignment does make a significant difference in terms of speed and space ?

< shrit[m]> jeffin143: I think we already remove the padding with g++ flags
< AakashkaushikGit> I also read the link that @jeffin143 sent but it is mentioned that you can add padding with compiler options but can't remove it and it was also mentioned that on X86 systems the difference is negligible
< rcurtin> a few data structures (including the decision tree) were manually tuned to reduce padding, but I'm not sure how huge of a difference it makes for most structs
< rcurtin> if anyone had interest in tuning more, feel free; it would be easy to benchmark the before/after to see if there is an improvement

< AakashkaushikGit> hey @iamshnoo I tried with ./bin/mlpack_catch_test and then with and without semicolon and with and without the cpp extension , I want to run loss_functions_test, Can you give a specific way ?
< zoq> AakashkaushikGit: bin/mlpack_catch_test "[TestName]" should work, make sure it's part of https://github.com/mlpack/mlpack/blob/master/src/mlpack/tests/CMakeLists.txt#L113
< AakashkaushikGit> No, it didn't worked though i ran just ./bin/mlpack_catch_test and all tests did passed so should i consider that the test i wrote for mean absolute error in loss_function_test also passed
< AakashkaushikGit> Also loss_functions_test is there in the CMakeLists.txt
< AakashkaushikGit> I just can't seem to run the loss_functions_test even after trying all the 6 combinations i could think of.
< zoq> AakashkaushikGit: If all tests pass that's fine, we run automatic tests for each PR, so once you open the PR, we are running all tests as well.
< jeffin143[m]> Please open a pull reuwy
< jeffin143[m]> Request , we can then help you Aakash kaushik (Gitter)
< anjishnu[m]> I just checked. The loss_functions_test file apparently uses BOOST test cases still, instead of Catch2 (?) So, maybe try compiling mlpack_test instead of catch_test and then run it using bin/mlpack_test -t TestName.
< jeffin143[m]> Yes loss function
< jeffin143[m]> Wasn't migrated
< anjishnu[m]> yep! Then this should work for him I guess.
< jeffin143[m]> You both are same??
< jeffin143[m]> I thought it'd your user name
< anjishnu[m]> <jeffin143[m] "You both are same??"> You mean @iamshnoo and this id?
< jeffin143[m]> Yes
< anjishnu[m]> Yep. I think iamshnoo is from Gitter. And this one is from Riot.
< jeffin143[m]> Oh I see
< AakashkaushikGit> Sure i would open a PR right away and thanks for helping on running tests.
< AakashkaushikGit> Done, Created the PR.
