# PCM: Peer Collaboration Mechanism

PCM is positioned as Software stack over Cloud, aiming to build the standards and ecology of heterogeneous cloud collaboration in a non intrusive and autonomous peer-to-peer manner. It focuses on how to make full use of the computing and storage capabilities of multiple source clouds without changing the heterogeneous cloud computing software stack, rather than implementing a new cloud software stack. From the cloud perspective, PCM superimposes on the cloud and focuses more on collaboration between clouds than on the cloud itself.

## Requirements

---

* Linux amd64

* [Slurm-2-6-9-1](https://github.com/SchedMD/slurm/archive/refs/tags/slurm-2-6-9-1.tar.gz)

* [Go](https://go.dev/) 1.19 or higher

* [GCC](https://gcc.gnu.org/) 4.8.5 or higher



## Quick Start

---

```
# clone
git clone https://gitlink.org.cn/JCCE/PCM

# get required packages
go mod tidy

# build pcm components
make build

# start service
nohup ./pcm-gateway &> pcm-gateway.log &
nohup ./pcm-pod &> pcm-pod.log &
nohup ./pcm-vm &> pcm-vm.log &
nohup ./pcm-slurm &> pcm-slurm.log &
```

If the startup is successful, the 'gateway' will listen on the '8880' port by default, and no error is reported in the log. The above is a simple demonstration using nohup. It is recommended that the production environment should be hosted by systemd. The relevant service files can be found in the etc/service directory for reference.
