The official pool miner for Protoshares is:
[ jhProtominer v0.1f by jh00 (Windows only) ]http://jhwork.net/ypool/jhprotominer.zip
Example usage: jhProtoMiner.exe -o http://ypool.net
-u <username>.<workername> -p <password> -t 4 -m512
The 64bit version of the miner is about twice as fast. It's recommended to set the memory to 512mb per thread using the -m512 parameter.
If you have a machine with low memory, then you can use -m128 or -m32 to use less memory but at the cost of mining speed.
For Linux or MacOS builds and generally optimized versions check out:
