Comment(by kazu-yamamoto):
If you send me an email with the error I can try to reproduce it
(I'm also on OS X).
The error is attached.
There are a number of kernel settings that need to be changed to run
some of these benchmarks. All of the settings are done automatically
for you by the `benchmark_shell.py` script. It can be used like so:
Thanks!
If you want to play with the code using `forkIO` style concurrency
(but using `Socket`s instead of `Handle`s) you can you
`System.Event.Thread` and `benchmarks/EventSocket.hs`.
I read it before. But I still want to use Handle for buffering.

I'm not quite sure what this is, looks like a 32 vs 64-bit issue. If you
don't need deadconn (which creates idle connections useful when
benchmarking scaling properties) you can build the target you want using
e.g. `make pong-server`.

It applies cleanly against both base 4.2.0.0 (as used in GHC 6.12.1) and the version used by HEAD. Simon, I think this patch is worth applying on top of base-4.2.0.0 as is, since it removes that pesky dependency on select. This would be a nice fix to have in GHC 6.12.2. For more substantial changes (use of epoll or kqueue), the amount of work involved is much higher. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/635#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

#635: Replace use of select() in the I/O manager with epoll/kqueue/etc. -+-- Reporter: simonmar| Owner: Type: task| Status: new Priority: normal | Milestone: Component: libraries/base |Version: 6.4.1 Severity: normal | Resolution: Keywords: | Os: Unknown Difficulty: Difficult (1 week) | Architecture: Unknown -+-- Comment (by simonmar): I should add that we'd prefer to do this using the I/O manager in the threaded runtime (libraries/base/GHC/Conc.lhs), rather than change the current select() machinery in the non-threaded runtime (ghc/rts/posix/Select.c). Volker's libevent patch is for the latter, I believe. -- Ticket URL: http://cvs.haskell.org/trac/ghc/ticket/635 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

We've known about this problem for ever, but haven't got around to doing anything about it. Here is a library that provides a unified API over the various event APIs: [http://monkey.org/~provos/libevent/]. See also [http://www.kegel.com/c10k.html]. 1 week is an estimate for doing it properly on all relevant platforms, by someone who is familiar with the APIs and code. -- Ticket URL: http://cvs.haskell.org/trac/ghc/ticket/635 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
