Joblo can you add the new BitSend (BSD) algo - XEVAN?

Quote
Here that is source package https://github.com/LIMXTEC/BitSend/blob/master/src/hash/xevan.h

It is a douple X17 with a another worknumber 128 (64)

Porting it to cpuminer-opt would be a challenge but forking the miner and optimizing the individual algos might be
possible. I'll have to look into it.

cpuminer-opt can't mine zcash, there are many devs working on zcash mining.

You can mine zcoin, not zcash. Order bigger glasses.

It's sad that cpuminer-opt doesn't support zcash because I need a zcash cpu miner with SOCKS/Tor proxy support and I don't know of any...   Cry

It seem that cpuminer-multi has already added this algo.
Maybe now you can add and optimise it Wink

The different data length could be a problem. The SSE2 macros are hard coded for 64 so they are out. It remains to be seen if
the other functions can handle a different data length.

Coding will be easy but lots of testing with no guarantees.

cpuminer-opt v3.4.9 released.

git: https://github.com/JayDDee/cpuminer-opt

tarball: https://drive.google.com/file/d/0B0lVSGQYLJIZR0V1eEZPLTVYQnM/view?usp=sharing

Windows binaries: https://drive.google.com/file/d/0B0lVSGQYLJIZNDJoR0xXZUxzWGM/view?usp=sharing

New in V3.4.9

- fixed zr5
- added xevan algo (Bitsend, BSD) with 10% improvement
- added lyra2zoin (Zoin, ZOI) fully optimized but YMMV

cpuminer-opt v3.4.9 released.
[...]

i have changed my git repo to be a fork of yours for easier merges on updates

also consider releasing the windows binaries on github (check my repo for example), its straight forward and provides all the good stuff from github directly

yep, i meant you can import it first.. and do opt if possible later Wink

imagine the pain on gpu kernels ... 17 to recode to handle more zeros Wink i let pallas try, if he has some weeks to waste ;p

Only one of the CPU optimized X11 sub-algos could handle a different data length, the others would have to be recoded,
not interested at this time.

v3.4.9 on XEVAN is still faster than bitbandi's cpuminer binaries released from BitSend team!
Thanks for adding it!

if your cpu is somewhat current see https://bitcointalk.org/index.php?topic=1326803.msg16613184#msg16613184

either way the intel builds are faster than btver and generic compiles, only native compiles directly on the system seem faster

I removed the btver1 build from the binary package because it did not have any optimizations and performed
on par with the core2 build.

I am also considering dropping the core-avx-i Ivybridge build because there are no optimizations targetted for
that architecture. The corei7-avx should perform just as well. Unless someone reports otherwise it will be dropped
from future releases.

I will change the name of the westmere and core2 binaries to match the naming convention of the other builds.
The architecture brand name will be included in the readme file to help users chose the correct binary.

The intent is to make the names more brand agnostic si users can matc to the CPU faeatures which should be
easier for AMD users. Example AMD models can be added as they become known.

proposed...
Code:
core-sse2:       SSE2,        Intel Core2
corei7:          SSE2 AES,    Intel Nehalem
corei7-sse41:    AES SSE4.1,  Intel Westmere
corei7-avx:      AES AVX,     Intel Sandybridge, Ivybridge
core-avx2:       AES AVX2,    Intel Haswell, Skylake

Feedback always welcome.

Keep your Z coins straight. cpuminer-opt supports ZCoin (XZC) and Zoin (ZOI). They each use a different variation
of the Lyra2 algo:

Zcoin: lyra2z
Zoin:   lyra2zoin

cpuminer-opt also accepts the coin names zcoin and zoin for convenience.

Zcash and Zcash Classic use the equihash algo and is not supported by cpuminer-opt.
There are also a number of other new Z clones using various algos.

I removed the btver1 build from the binary package because it did not have any optimizations and performed
on par with the core2 build.

I am also considering dropping the core-avx-i Ivybridge build because there are no optimizations targetted for
that architecture. The corei7-avx should perform just as well. Unless someone reports otherwise it will be dropped
from future releases.

I will change the name of the westmere and core2 binaries to match the naming convention of the other builds.
The architecture brand name will be included in the readme file to help users chose the correct binary.

The intent is to make the names more brand agnostic si users can matc to the CPU faeatures which should be
easier for AMD users. Example AMD models can be added as they become known.

proposed...
Code:
core-sse2:       SSE2,        Intel Core2
corei7:          SSE2 AES,    Intel Nehalem
corei7-sse41:    AES SSE4.1,  Intel Westmere
corei7-avx:      AES AVX,     Intel Sandybridge, Ivybridge
core-avx2:       AES AVX2,    Intel Haswell, Skylake

Feedback always welcome.
avx2 build is missing in v3.4.9
