[R-SIG-Mac] multithreading package failure?

[Simon Urbanek]

Jan,

it fails due to timeout (i.e. the build gets killed after 30 minutes which is why you don't see any further output). So could it be that your example just take too long to finish? If it helps, this is the tail of the output:

$ tail ruimtehol-Ex.Rout
+                             dim = 25, epoch = 25, minCount = 2,
+                             negSearchLimit = 1, maxNegSamples = 2)
Start to initialize starspace model.
