# apt-get --purge remove *legacy*
did the job.
I wonder how these legacy packages entered the scene while updating/upgrading from a clean wheezy.
The bad news are that with the new driver 319.60 there was no acceleration of molecular dynamics for a job of modest size (150K atoms) and slight acceleration (0.12 s/step vs 0.14 s/step) for a heavy job (500K atoms). Weather bringing from PCIe 2.0 (with the 304.xx driver of wheezy) to PCIe 3.0 (with driver 319.60 of jessie) (increasing the bandwidth from GPUs to RAM from 5 to 8GB/s) has not the effect that I hoped on the calculations, or PCIe is still 2.0 with jessie.
Now, with cuda 5.0, it should be easy to measure the bandwidth directly. I have to learn how and I'll report about in due course.
nvidia-smi activates the GPUs for normal work,
nvidia-smi -L tells about the GPUs,
dpkg -l |grep nvidia shows all 319.60 or 5.0.35-8,
the X-server can be started and gnome loaded (startx, gnome-session),
nvcc --version gives 5.0, however
# modinfo nvidia
ERROR: module nvidia not found
In analogy with wheezy 3.2.0-4, I expected /lib/modules/3.10-3-amd64/updates/dkms/nvidia.ko
Instead, there is
is that a feature of jessie or something wrong?
Thanks a lot for advice.
