[Mono-dev] Mono.Simd and Threefish256
As part of my free time, I decided to start down the path to SIMD-ing some cryptography algorithms. As a starter exercise, I took Threefish256 from the SHA-3 submission Skein. The experience was very enlightening, and as I haven't been able to find anything of substance out there about working with Mono.Simd, I thought I'd write some articles about it. I'm posting my experience to my blog in a 5-part series. The first of the posts has already been published, and I'll have the rest ready by the end of the weekend: http://blog.xpdm.us/2009/10/01/skein-threefish-and-mono-simd-part-1/ Thanks to all the folks who've been keeping the Mono.Simd project going. -- Marcus Griep signature.asc Description: This is a digitally signed message part ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
Re: [Mono-dev] Update C5 to v1.1.0
I have posted an update with the unit tests disabled. Because the first patch was large and difficult to prepare in the first place, I have let it be, and added a second, meta patch, which is to be applied to the results of the first patch. Here are the links again: http://wiki.xpdm.us/_media/mono/v1.1.0.patch.gz http://wiki.xpdm.us/_media/mono/v1.1.0.meta.patch They should be applied in that order, and the result should `make check` properly. I still have not heard back from the original maintainers, so I will be working proactively to maintain the library going forward, including fixing up the test cases and general code base to quality expectations.

[Mono-dev] [PATCH] Change Mono.C5 from common lib to net_2_0 lib
Currently Mono.C5 builds even as part of the net_1_1 profile. This is
unnecessary as Mono.C5 provides and consumes generics, and thus depends
on net_2_0 at minimum. In order to build in net_1_1, all the files in
Mono.C5 are surrounded by #ifdef NET_2_0 directives, leading to
effectively empty files being built into an uninstalled library in the
net_1_1 profile.
This patch cleans up the Mono.C5 build by moving it to the net_2_0
profile and removing the now unnecessary #ifdef guards.

[Mono-dev] [PATCH] Squash 444388 and catch miss on 323096
Bug 444388 [https://bugzilla.novell.com/show_bug.cgi?id=444388] is a
pretty obscure bug that hits very few people, but I find myself among
them. Attempting to bring the latest version of C5 to Mono, I found an
issue with member resolution when interfaces hide members of parent
interfaces.
After sitting on it for a while, I was able to reach my own itch. The
full explanation is long, and if you're interested in the background of
the bug and how I came to this patch, check my *full* writeup here:
http://wiki.xpdm.us/mono/bug444388.
The executive summary is that this patch fixes 444388, and also fixes a
bug introduced by the fix to 323096 (which caused incorrect resolution
in similar cases). As well, it adds two additional test cases to the
test suite to prevent future regressions.
If that's too succinct, let me know, and I'll respond more fully to the
list.

[Mono-dev] Integrating Mono.Simd into Mono.Math, Mono.Security
Hello all, First, by way of introduction, I'm Marcus Griep, a .NET/Mono developer for some time now, and a contributor to such projects as Boo, C5, and git. In a sort of scratch-my-own-itch style, I'm looking to speed up the computationally time consuming steps of BigInteger math by using Mono.Simd in Mono.Math. This would then vicariously speed up various cryptographic functions that rely on BigIntegers, such as primality tests in RSA, and could be futher extended to using Mono.Simd throughout Mono.Security. Mono.Math resides within Mono.Security, so I would be creating a dependency from Mono.Security to Mono.Simd. Also, Mono.Math is incorporated internally within corlib, which would probably mean interning Mono.Simd in corlib as well. One confounding factor is that Mono.Simd uses extension methods, thus depending on System.Core, and being a 2.0-only library. With the 1.1 world still around, incorporation of Mono.Simd into corlib and Mono.Security will probably require some precision cuts to get 1.1 working independently of Mono.Simd, while letting 2.0 utilize it. (Another option is to reduce the dependency on the VectorOperations extension methods, making them normal static methods when built to 1.1). The intended outcome is that Mono's cryptographic libraries will see a nice speedup when run on systems supporting SIMD. Since this is my first major delve into Mono, in a contributory sense, any input, corrections, or advice are welcome as I try to wrap my head around what actually needs to be done. -- Marcus Griep GPG Key ID: 0x070E3F2D —— https://torproj.xpdm.us Ακακια את.ψο´, 3° signature.asc Description: OpenPGP digital signature ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
