I thought of N-Cube machines when I saw it, CM didn't even occur to me.

Worked on the CM-1 and CM2. I felt they were awful buggy. At one point they asked if they could use my code to run as a diagnostic, it would break the log() function on occasion. The Cray fluorinert fountains were way cooler :)

Reminds me of DOGE :)

Physical appearance or architecturally?

Yeah, ours was a fluid dynamics problem that needed information from neighboring cells. So at some point there needed to be data moving between cells and that really killed performance. There was also a global value that need to be compute

Yup, getting the the problem to fit the machine was hard. I thought NCUBE was better than the CM1 for doing actual work. Some people resorted to just running each node separately, after the initial conditions were set up there was no need f

Would you care to elaborate on why? I had to work on one and didn't really see what the fuss was about. Performance still sucked compared to a Cray2. I mean it was supposed to be a Supercomputer... I/O was painfully slow so unles

I thought it (CM1) was a turd when I worked on it as a grad student. Looked cool though. I would go to conferences where people would proudly present their algorithm getting 1MFLOP. Parallel programming was hard then and it is hard now. SI

Yeah she had one of these too.

It was not all that easy to get to and not all that easy to mount a switch securely near by. May be I just lacked imagination. The real reason and the part I skipped was the leakage current was getting worse over time. By the time I repla

I had a 2005 Acura RL which had some pretty fancy electronics for its time. I gave it to my daughter a few years ago and she started reporting that the battery was dying. It would take several days to die, so at first she just jump start
