Is there a 64bit version of the GridRepublic Client software?
I see a 64bit version of the BOINC client software.
I just installed the gridrepublic_6.8.20_windows_intelx86.exe version
There is no 64 bit version of the GridRepublic client at this time. There has been a 64 bit application in the past. Not sure when it may return.
For simplicity, we've been offering only a single client. This might change in the future.
But, please note that the client performance isn't really important. Even if you have a 32 bit client, you automatically will get 64bit versions of the science apps, if these are appropriate and available from projects. So the scientific computing work will be done, I think, in the optimal way. (Note that not all projects have 64 bit science apps.)
