Hi tromp:

When I run cuda29, I got GPUassert: out of memory mean.cu 377 error, Is there any problem with my program? Tell me if the information above isn't enough.

cuda29 requires 7 GB, but you can use option -E 1 or -E 2 to reduce memory to either 5 GB or 4 GB.

regards, -John

Hi John,

Use -E 1 works like a charm, thank you so much!
