We've added a few more servers to the 200 series and will hopefully add a few more next week. In all we should increase our cluster by about 18 cores. To cope with this we've modified our dashboard to more clearly reflect the distinct server types. In addition we've blended the 400 and 400M series; directives requesting large memory machines will be constrained by the 400M subset while requests for 400 series servers will include all servers in the 400 and 400M range.
Not all of the 200 series servers have 8GB RAM, there are 2 with 16GB and 3 with 4GB. We will upgrade the 4GB machines to 8GB soon and probably leave the 16GB RAM unless we need to utilize the chips to increase the memory of any new 200 series servers. Users wanting to ensure consistent memory geometry should make use of the PBS mem= directive.
