Do I need another minerd? I'm testing it on my own comp, and my minerd - ver. 2.3.2 - doesn't recognise the parameter -a quark in the command like this:
./minerd -a quark -o
http://prt.mine-pool.net:9472 -O address:pass
Newer versions of the original Minerd no longer support quark. There are some optimised "forked" versions of Minerd depending on what system you have. Which are still developed which still support Quark;
This is what I'm currently using;
http://sourceforge.net/projects/philosopherstone/files/QRK/I'm using the i3i5i7_Improved version since I have an i5-3570K and I get 640kh/s (stock clock freq) when mining Particle. Yields me around 20k Particles per day.
