cuMatrix host memory allocation failed

[FelixZhang00]

when I run ./CUDA-CNN 1 and get this error 'cuMatrix host memory allocation failed'.Can you fix this.
I run this on Max OSX 10.11.

I think your computer's memory is limited. You can edit the config file to resize the network

[FelixZhang00]

I run this code on a 16GB-Memory MacbookPro,does it ok?
After I edit the config file to resize the network,I get the same error.The total message is:

1. MNIST
2. CIFAR-10
3. CHINESE
4. CIFAR-100
5. VOTE MNIST

What is your GPU version？ You should check your cuda drive is installed sussessfully.

[FelixZhang00]

I think the environment is correct,and I can run the cuda code to get the GPU info:
--- General Information for device 0 ---
Name: GeForce GT 750M
Compute capability: 3.0
Clock rate: 925500
Device copy overlap: Enabled
Kernel execution timeout : Enabled
--- Memory Information for device 0 ---
Total global mem: 2147024896
Total constant Mem: 65536
Max mem pitch: 2147483647
Texture Alignment: 512
--- MP Information for device 0 ---

Shared mem per mp: 49152
Registers per mp: 65536

Compute capability: 3.0, Your IDE should config the gpu capability 3.0 or edit the cmakelist.txt

[zhxfl]

Have you run "sh get_mnist.sh" to get the datas

[FelixZhang00]

Yes,I have these data on the correct path.

[zhxfl]

Can you debug the code and give me more informantion? I need the Stack information.

[FelixZhang00]

I try just read mnist to cuMatrixVector trainX, and not compile layers ,is ok.But when I compile and link the layers to target , the error happen again.Why this happen?

[FelixZhang00]

I find the place of this error.
in Pooling.cu,if delete 3 functions ,then the code can run correctly.
These functions:
g_pooling_feedforward_max
g_pooling_backpropagation_max_no_atomic
g_pooling_backpropagation_avr_no_atomic

[zhxfl]

I have remove the code "//cudaFuncSetCacheConfig(g_pooling_feedforward_max, cudaFuncCachePreferL1);", You can try it again.

[FelixZhang00]

by the way,when use you config to train mnist,it's too slow.
epoch=1 time=194.826s , is it normal?

[zhxfl]

Yes, It is normal. You can editor the config file to improve the performance

我这边选择1以后 最后显示
total malloc cpu memory 0.00000MB
total malloc Gpu memory 0.00000MB
cuMatrix Vector operator[] error
楼主 求指导以下- -找不到原因了。。
