After months of doing boring stuff like adding new hash-types and architectural changes I decide to do only fun stuff today. For me that means: Optimization

For all AMD GCN based cards (HD7970, R280*, R290*, etc), I've added a new some optimization that I can use nearly on all raw-sha1 fast hashes to increase performance again.

STRAIGHT mode with rules:

• old SHA1: 1765
  
• new SHA1: 1774
  
• old SHA1 $p.$s: 1430
  
• new SHA1 $p.$s: 1624
  
• old SHA1 $s.$p: 1548
  
• new SHA1 $s.$p: 1704
  

COMBINATOR/HYBRID mode:

• old SHA1: 1911
  
• new SHA1: 2160
  
• old SHA1 $p.$s: 1652
  
• new SHA1 $p.$s: 1936
  
• old SHA1 $s.$p: 1784
  
• new SHA1 $s.$p: 2017
  

MASK mode:

• old SHA1: 2724
  
• new SHA1: 3037
  
• old SHA1 $p.$s: 2724
  
• new SHA1 $p.$s: 3037
  
• old SHA1 $s.$p: 1842
  
• new SHA1 $s.$p: 2165
  

I've packed this stuff on oclHashcat v1.34 beta 1. Beta-testers can download it from the known locations. Have Fun!
