cuda1.tarbox.org has two Nvidia CUDA cards, but its really just a conventional machine with a few extra (proprietary... ugh) drivers and development tools. I haven't noticed any issues in the past... not that there weren't any, just didn't notice. Also, since upgrading to the latest Ubuntu, I didn't install / upgrade / bother with the cuda stuff. I put the "lspci -vvnn", lshw and "dpkg --get-selection" outputs up at: http://hq3.tarbox.org/sage/ Probably overkill in answering your question. A diff spewed way too much output to be useful on the packages although someone with an idea of what they were looking for might find them useful. thanks, -glenn > > Differs between the two libpng-config, libpgn12-config and the header files > might reveal why one is usable and the other is not. > > Dave -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
