# Regular Meeting (2020.9.14)

1. Burn-in new PC (RAM r/w test)
2. New PC and Xilinx Alveo
3. Regarding 2 opt modules do loopback
4. PAM4-doc (written by intel)

## 1. Burning new PC (RAM r/w test)

* No error occured

* Now PC state: without OS
* will install

* Test program is launched before loading the BIOS, OS isn't necessary


## 2. New PC and Xilinx Alveo

### 2.1 Short summery

In the our new PC:

* U50(NT$100k) + VGA
* bandwidth of PCI-E can't be shared
* no problems for our new PC

* U200/250(NT$300k) + VGA
* bandwidth of PCI-E can be shared (/2)
* a solution:
* take out the VGA, testing Alveo with command-line

* Bandwidth affects I/O performance between RAM and VGA
* Frequently R/W between RAM and VGA via PCI-E
* **but normally computing can frequently R/W between RAM and VGA via PCI-E?**
### 2.2 Bandwidth of PCI-E


### 2.3 U50 and U200/250

* U200/250
* U50

### 2.4 Configuration for multiple device on PCI-E in our MB


## 3. Regarding 2 opt modules do loopback


## 4. PAM4-doc (written by intel)
