# umdk

#### Description
The Unified Memory Development Kit(UMDK) is a set of distributed communication software stack with memory semantics as the core. It aims to design a new-generation network architecture through software-hardware collaboration, subvert the traditional communication form, and build a computing native network centered on memory semantic interconnection.

#### Software Architecture

urma                          : URMA (Unified Remote Memory Access)
                                The URMA subsystem provides high-bandwidth and low-latency data
                                services in the UBUS system. Provides basic functions of message
                                communication and data forwarding for various services in the data
                                center. For big data services, the end-to-end communication delay
                                is reduced. High-bandwidth and low-latency services are provided for
                                HPC and AI services.

```

#### URMA Installation

1. Compile environment configuration
- You need to install the following dependency packages

```bash
  yum install -y rpm-build
  yum install -y cmake
  yum install -y make
  yum install -y gcc
  yum install -y gcc-c++
  yum install -y glib2-devel
  yum install -y libsecurec-devel
  yum install -y elfutils-devel
  yum install -y rdma-core-devel   # You may need to provide it yourself
```

2. Build and install
- You can build and install the ubus rpm packages by:

```bash
  tar -czf /root/rpmbuild/SOURCES/umdk-urma-1.3.0.tar.gz --exclude=.git `ls -A`
  rpmbuild -ba urma.spec
  rpm -ivh /root/rpmbuild/RPMS/*/umdk*.rpm
```

- Alternately, you can build your programs manually in the code folder for debug.

```bash
  mkdir build
  cd build
  cmake ..
  make install
```

3. Compilation Options
- RPM compilation Options

```bash
  $ --with transport_service_disable                  option, i.e. enable TPS by default
  $ --with hw_disable                                 option, i.e. enable to compile hw driver by default
  $ --define 'kernel_version 4.19.90'                 option, specify kernel version
  $ --define 'rpm_version 1.4.0'                      option, specify rpm version
  $ --define 'rpm_release  B002'                      option, specify release version
```

- cmake compilation Options

```bash
  $ -DTPS=disable                                     option, i.e. enable tps service by default
  $ -DHW=disable                                      option, i.e. enable to compile hw driver by default
```
