Caffe Framework Runtest Core dumped error

Question

I have been installing Caffe Framework with the following GPU: Geforce 9500 GT CUDA 6.5 (not work with 7.0)

when I run: make runtest the following errors appeared and I don't know what are the reasons:

 make runtest
.build_debug/tools/caffe
caffe: command line brew
usage: caffe <command> <args>

commands:
  train           train or finetune a model
  test            score a model
  device_query    show GPU diagnostic information
  time            benchmark model execution time

  Flags from tools/caffe.cpp:
    -gpu (Run in GPU mode on given device ID.) type: int32 default: -1
    -iterations (The number of iterations to run.) type: int32 default: 50
    -model (The model definition protocol buffer text file..) type: string
      default: ""
    -snapshot (Optional; the snapshot solver state to resume training.)
      type: string default: ""
    -solver (The solver definition protocol buffer text file.) type: string
      default: ""
    -weights (Optional; the pretrained weights to initialize finetuning. Cannot
      be set simultaneously with snapshot.) type: string default: ""

Answer 1

It turns out that (as @Jez suggested) my GPU does not support double precision which used by Caffe math functions. That's the reason for crashes. I have searched for workaround on this issue but haven't found one. Maybe the only solution is to use more modern GPU
