Integrate parallelMap about mlrmbo HOT 13 CLOSED

• if more than 1 point is proposes

from mlrmbo.

Jakob, please do only the above two things.

If you want to do it in more places, discuss it here.

from mlrmbo.

I added parallelMap in evalTargetFunction

from mlrmbo.

Jakob, is this done for all places where the target function is evaluated?

from mlrmbo.

After that I could think of 1-2 more places, that we can discuss, then we can close.

from mlrmbo.

I think it is done for all places in our mbo core function and all called functions.

Of course the exampleRun function also makes heavy use of function evaluations. What places are you thinking about?

from mlrmbo.

1. exampleRun: Good idea. If not parallel, do it now.

2. In parallelLCB the different lcb function can be optimized in parallel. This is expensive. Do this, too.

If parallel is tested after that in 2-3 modes, pls close for now.

from mlrmbo.

Added parallelMap to exampleRun. Works fine with the testet modes local and multicore.

Where is 2) located? Can't find it :-)

from mlrmbo.

1. You should always test with "socket" too, because in this mode variable are potentially exported.
   multicore uses forking = mem sharing with master.

2. It is in multipoint lcb. Leave this to me for another reason. I will also close this.

from mlrmbo.

Before I forget: You also must document in all related R docs that the functions are now parallelized!

from mlrmbo.

You told me where to annotate, that parallelization is possible, but I unfortunately forgot it.

from mlrmbo.

Document it somewhere at the end of mbo.

Then either explain it in the tutorial, very BRIEFLY, or add a new isse for that.

from mlrmbo.

I added a @note to the documentation of mbo and referenced the parallelMap package and the mlrMBO tutorial.
