I'm not sure if this has much significance or not -- but it sounds rather ominous. It doesn't appear to be new as it happens with 2.0.0 in Linux (but the formatting of the warning messages has improved). > contour(array(3e10, c(10,10), list(1:10, 11:20))) Warning: stack imbalance in 'contour', 20 then 24 Warning: stack imbalance in '.Internal', 19 then 23 Warning: stack imbalance in '{', 17 then 21 Warning message: all z values are equal > sessionInfo() R version 2.4.0 RC (2006-09-27 r39543)...

...iterations - all the implementations are scalable. - RcppRandomSFMT and random_r are an order of magnitude faster than rlecuyer and rngOpenMP - actually RcppRandomSFMT and random_r have very similar performance. The problem with random_r is that its cycle length according to my manpage is ~ 3E10, enabling for instance only 3 millions permutations of a vector of 10,000 elements, to be compared with Leaving the RcppRandomSFMT as best candidate. This implementation also allows multiple seeds, solving my requisite number 4, reproducible results independent of the number of threads, if I use a...
