I stop helping RSA because we you already know the project will be closed by the end of the month and right now the server is full. All integers ready for post-processing are already reserved by others so I moved my help to NFS@Home. As can be seen here the RSA equivalent is live! Done two jobs and a third will end within ~12 hours.
So by moving CPU power from RSA to NFS@Home (please check lasieved - app for RSALS subproject, uses less than 0.5 GB memory to yes) you will make a favour to RSA. The advantage of running the NFS@Home under Linux is that the application is 64-bit compatible so you will get double credit and the speed is double when comparing to the 32-bit siever of the RSA. Also NFS@Home shares a wide range of the sievers for other platforms. I understand you all want to reach some milestones but RSA server is only 160 GB of space available and so it's very difficult to manage such space with post-processing stage.
