可以看到在提交任务的时候，我们指定了以下参数:
- `-jobname fit-a-line`, 任务名称
- `-cpu 1`, 使用的CPU资源
- `-gpu 1`, 使用的GPU资源（卡数），若集群无GPU资源，可以去掉这个配置
- `-parallelism 1`, 并行度(训练节点个数)
- `-entry "python train.py"`, 启动命令
- `-entry "python train.py train"`, 启动命令
- `fit_a_line` 任务程序目录

***说明1：*** 如果希望查看完整的任务提交参数说明，可以执行`paddlecloud submit -h`。

***说明2：*** 每个任务推荐使用不同的jobname提交，这样之前的任务的代码和执行结果都会保存在云端。

***说明3：*** 如果提交的节点比较多，可以先修改启动命令中的参数`-entry "python train.py prepare"`，先将数据集下载到PFS上，再提交训练任务。

## 查看任务运行状态和日志

任务启动之后，可以用过命令`paddlecloud get jobs`查看正在运行的任务：
