Deadlock on GPU when using NEW and matrix size is large

[QingleiCao]

Describe the bug

There is a deadlock when running on GPU. This deadlock happens when using NEW with a large matrix size (memory does not fit into GPU memory).

To Reproduce

Steps to reproduce the behavior:

1. Checkout version 'commit-hash'
2. Compile with the following options '....' [e.g., head config.log]
3. Run test '....' [e.g. ctest --output-on-failure -R xyz]
4. See error

Expected behavior

A clear and concise description of what you expected to happen.

Environment (please complete the following information):

• PaRSEC version: [e.g., git hash]
• OS: [e.g. CentOS/7]
• Compiler: [e.g. GCC/7.3.0]
• MPI version: [e.g. Open MPI/4.1.2]

Additional context

Add any other context about the problem here.
The content of the config.log file can be useful in some cases.

This is because when handling PARSEC_FLOW_ACCESS_WRITE in device_cuda_module.c, NEW is not considered in some cases when the matrix can not fit into GPU memory. But I need to understand more about this.
