I tried running the science collection examples in 3.99.  Most of the plots were just empty, so I need to see if it's a problem with the PLoT package or with my code.  [They didn't error, just gave empty plots.]  For the ones that did run and which are computationally intensive (with flonums) - like Chebyshev evaluation and (especially) the ordinary differential equation solvers - they 'seemed' much faster.  But, it's anecdotal - I just eyeballed it.  I have to track down my uses of set-cdr!, etc in the simulation collection before I try any of my larger examples there. <br><br>One interesting problem came up.  Has the use of subcollections in PLaneT changed with 3.99?  For example, (require (planet "bernoulli.ss" ("williams" "science.plt") "random-distributions")) says it can't find the file, but it works fine in V372 (and before). <br><br>Doug<br><br><br><div class="gmail_quote">On Dec 28, 2007 3:55 PM, Noel Welsh <<a href="mailto:noelwelsh@gmail.com">noelwelsh@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Joyous day!  Should my code run in 3.99 I'll do some benchmarking.<br><font color="#888888"><br>N.<br></font><div><div></div><div class="Wj3C7c"><br>On Dec 28, 2007 10:52 PM, Matthew Flatt <<a href="mailto:mflatt@cs.utah.edu"> mflatt@cs.utah.edu</a>> wrote:<br>> The latest in SVN (v3.99.0.7) includes new JIT support on x86 for<br>> inlining flonum (i.e., inexact real) arithmetic.
