One should definitely look into possibility of buying a BladCenter. The support for InfiniBand and Server RAID, many storage options and highly configurable interfaces make this system an outstanding hardware to work on. There is always an opportunity for hardware diversity also. That makes

I am not familiar with such high-end hardware but I think it would be great to have 2 more sunfire 4450s. I have used sage and geom for research computations, and they are often quite heavily loaded. -Marshall On Jan 22, 1:52 pm, William Stein wst...@gmail.com wrote: Hi, We are considering

I also think that it would be nice to get the same machines - it is convenient to be able to switch to another machine when another has problems or is heavily loaded. Also, it seems that there are regular fast disk problems - is it possible to get analogs of sage.math /scratch on all machines?
