我在大学里尝试在HPC上使用SLURM运行cupy。我得到以下错误：
PermissionError: [Errno 13] Permission denied: '/home/username'
我认为发生这种情况是因为计算节点没有访问/home的权限。由于整个错误显示

我假设它是一个缓存目录，无法在/home/username中创建我是否有机会将此缓存目录更改为在/shared storage/username中创建？
设置环境变量CUPY_CACHE_DIR，请参阅https://docs-cupy.chainer.org/en/stable/reference/environment.html.
