Note also that older toolchains require older host compilers and support libraries. My current development box has every release between 4.2 and 7.5 installed, with the 7.5 driver. I have found the modules utility very useful for selecting between toolkit/runtime versions for development and testing. You cannot, however, run a newer runtime on an old driver. So you can use the CUDA 7.5 driver and driver API with either the CUDA 5 or CUDA 7.5 runtime without difficulty. However, drivers and the driver API they expose are backwards compatible. I can't comment on the virtualisation suggestion, however, there is no problem in running the most recent release driver (so CUDA 7.5 at the time of writing) and using older toolkits with it.Įach CUDA toolkit release and its components are fully versioned, so you cannot mix the CUDA runtime and other libraries (cuFFT, CUBLAS, etc) from different toolkit releases or your own code built with those. What do you think about these possibilities ? Do you have any idea ? Is it possible to run SDK 5 with latest driver ?

Install latest nvidia driver and use two NVidia docker containers with different Cuda SDK and Debian versions.

Which driver I have to install at the hypervisor level ? I can not view these video cards in their compatible hardware list but one NVidia driver release notes say they are pass through ( 320.78 release notes at page 11).

A VMWare ESXI or Citrix XenServer hypervisor which allow to create two virtual machines (Wheezy/SDK 5 and Jessie/SDK 7.5) connected to K20 cards in pass through mode.

The main goal is to get two different CUDA versions on this server to keep compatibility with older computations and to prepare future with CUDA new features. I already evaluate CUDA 7.5 which give me different results than CUDA 5 because of used instructions by NVCC (e.g.: FMA instructions are not used at same places, see post).

I actually use CUDA 5 with 304.54 driver and GCC 4.6.3 but I would like to update to Debian Jessie (GCC 4.9) and CUDA 7.5.

I work on bi-processor Debian Wheezy server with 4 Nvidia K20m cards.
