Pinkish, a replacement for ed, is a 128-node LinuxBIOS/BProc cluster with dual 2.4 GHz P4s connected by Myrirnet 2000. Pinkish is nominally a 1 TeraFlop system. The vendor is ProMicro Systems.

1/7/2003:
| 117 nodes of pinkish are up. The remainder are down due to bad Myrinet cards or switch ports. |
|
 |
Each nodes has only 2 wires going to it: power and Myrinet fiber. This makes life a lot easier in terms of initial wiring and maintenance, and it's also a lot cleaner looking. |

As is always the case, we didn't want the rack doors, so we removed them and put them outside. |
10/22/2002:
32 nodes of pinkish are up in their temporary location. We stole the power controllers from ed to get them plugged in to ed's old spot.
10/4/2002:
Still no power for pinkish, but we've removed the Myrinet cards from ed and they are ready to be installed. Erik got the front-end up as a BProc master.
10/1/2002:
| Pinkish arrived at the ACL in a bit of a frenzy. The space for pinkish had not been vacated, so we had to improvise. To add to the pain, the racks were 44U, and all the doors to the machine room fit up to 42U racks. |
|
| |
Our delivery guy, Danny, and his forklift-drivin' friend unloaded the 6 racks outside the machine room doors with great finesse. |
|
|
|
| As mentioned above the racks were 2U too tall (left), so we removed the doors and began unracking the nodes (right). |
|
|
|
|
| Once the rack were empty, we raised the feet (left) and rolled the racks off the pallete (right).
|
|
| It took six people to carry each rack into the machine room. |
|
| |
After each rack was carried in, we re-racked all the nodes. More than a handful of parts were broken or lost during this process. |
