Hi cafe,
The rtsopts (-s etc) can provide some nice debugging information regarding
memory management. And System.Mem.performGC can initiate garbage
collection. But are there APIs for querying the current state of the heap?
I've googled and come up dry.
In this case I'm running benchmarks and
Hi all,
I released the intel-aes package which has support for AESNI (and as a
fallback uses the same C code as AES, both with Thomas's
Crypto.Classes.BlockCipher interface).
But it has a long way to go to be portable. I'm afraid of exactly these
sorts of compiler problems. For arguments sake,
Oops, I guess I misinterpreted package description. It did sound a little
dangerous ;-).
What you suggested also worked. I'm in good shape now.
Thanks again,

This is what Burton Smith originally thought, that AES based RNG would be
pretty fast and even faster with hardware acceleration.

Hi cafe,
I am trying to link a .a file built by a separate makefile into my
library. GHC has no problem with it, but I need to convince cabal to do it
for the package to be hackage-friendly. There's a thread about this back in
2007:
/libintel_aes.so obj/x64/intel_aes.o

Yes, I don't understand that either
Hi cafe,
I want to add the ability to use AES-NI instructions on Intel architectures
to GHC. Mainly I'd like to do splittable random number generators based on
AES as was suggested at the outset of this email. (I met Burton Smith last
week and this topic came up.)
I was just reading the below

So a naive implementation of split would be:
split g = (mkGen seed, g')

Just to be clear, that is the same as Burton Smith's original proposal that

What's the easiest reference for how to build GHC head and get it up

I simply installed 6.12 + haskell-platform then built ghc-6.13.xx and

Perhaps this is not the recommended way.
