Hello: I have just set up a gaming machine with
Gigabyte GA 890FXUD5 AMD Phenom II 10775T 2 x GTX470 GPU cards 4 x 4GB RAM 2 x 1 Tb HD for RAID1 and need to install amd64 to run molecular dynamics using (free for non-commercial use) NAMD software (released binary below or compilation from source). All that is experimental, with little experience and I have no experience whatsoever with CUDA cards. My question is about the version of amd6a to be best used (lenny or squeeze) and what should be added to the typical server installation according to the requirements: (1) NVIDIA Linux driver version 195.17 or newer (released Linux binaries are built with CUDA 2.3, but can be built with newer versions as well). (2) libcudart.so.2 included with the binary (the one copied from the version of CUDA it was built with) must be in a directory in your LD_LIBRARY_PATH before any other libcudart.so libraries. For example: setenv LD_LIBRARY_PATH ".:$LD_LIBRARY_PATH" (or LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH"; export LD_LIBRARY_PATH) ./namd2 +idlepoll <configfile> ./charmrun ++local +p4 ./namd2 +idlepoll <configfile> THE FOLLOWING CAN BE SKIPPED, unless one is specifically interested in the matter: The +idlepoll in the command line is needed to poll the GPU for results rather than sleeping while idle, i.e. NAMD does not use any non-specified GPU card. Each namd2 process can use only one GPU. Therefore you will need to run at least one process for each GPU you want to use. Multiple processes can share a single GPU, usually with an increase in performance. NAMD will automatically distribute processes equally among the GPUs on a node. Specific GPU device IDs can be requested via the +devices argument on the namd2 command line, for example: ./charmrun ++local +p4 ./namd2 +idlepoll +devices 0,2 <configfile> Thanks for advice francesco pietra -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
