Unable to run pyrit_0.3.0 On Non SSE2 cpus - Patch needed #250

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Unable to run Pyrit on Non SSE2 Cpus

What is the expected output? What do you see instead?

Pyrit should autodetect whether the cpu has SSE2 or MMX, it does not, tested on 
multiple coppermine cpu bases sytems as well as Multi Proc Katmai XEON servers.

What version of the product are you using? On what operating system?
Pyrit-0.3.0 on Ubuntu Server Karmic 9.10  

Please provide any additional information below.

There is a small bug in 0.3.0 that makes Pyrit use the SSE2 core even if only 
MMX is available. Such configuration is only present on some older CPUs, 
therefor the bug went undetected for quite some time. It was fixed in 0.4.0-dev 
r271 and is fixed in Debian's and Ubuntu's packages of 0.3.0

Can you check /proc/cpuinfo if you processor does support MMX but not SSE2 - 
the latest version from svn should work for you in this case.

yes I have the latest svn of 0.4.0 now and the issue is gone, lol, now I know 
why no one noticed. see below for the reason, lol

Running benchmark (103.3 PMKs/s)... /

Computed 103.30 PMKs/s total.
#1: 'CPU-Core (x86)': 32.8 PMKs/s (RTT 8.0)
