tegra k1开发板使用注意事项汇总
1.tegra k1开发板监控GPU的使用率命令:
在L4T ubuntu 14.04下测试可用:
To monitor GPU utilization I just view the current load of the GPU by checking in on this file.
cat /sys/devices/platform/host1x/gk20a.0/load
If I want to monitor it, I use watch with the file.
watch -n 1 cat /sys/devices/platform/host1x/gk20a.0/load
I am interested if anyone has figured out a similar way to monitor CPU load from the command line.
2.caffe编译后需要修改源代码才能避免跑cifar10时出现segmentation fault
修改src/caffe/util/db_lmdb.cpp,把以下的SIZE改小,这里改为1GB= 1073741824字节
const size_t LMDB_MAP_SIZE = 1073741824
运行cifar10通过
