    Hi everyone. I re-started crunching pulsar data a couple of months ago. I had installed the client and manager from the Ubuntu 10.04 repositories (v 6.10.17). I wanted to check out the the newer version, so I waited until the pending tasks were completed and then switched to the new version (6.10.58). Prior to the uninstallation of the old version, I noticed about 214 MB was being used by BOINC projects (which, then and right now, is only E@H). But with the new version, it is starting from 0 all over again.

    Is that 214 MB worth of data still sitting somewhere on my hard-disk, taking up space (uselessly?)?

      Hi!

      The bulk of data that E@H uses is stored in files that can easily be found. Log-in as user root and execute the following commands to perform a brute-force search of your filesystem:

      find / -name "h1_*S5??" | grep projects | xargs -l dirname | sort | uniq

      find / -name "l1_*S5??" | grep projects | xargs -l dirname | sort | uniq

      find / -name "p2*.binary" | grep projects | xargs -l dirname | sort | uniq


      This should indicate all directories where those files are still lingering around (including the legitimate directory used by your current BOINC installation).

      Hope this helps
