- I have some C* programs which ran fine on a Thinking Machines'
- CM-2 (they were fractal algorithms, and very well parallelizable).
- Now, there is a CM-5, and I am curious as to the difference. Is there
- a text file anywhere (FTP?) which describes the difference between
- them from the point of view of the user (i.e., I don't need any
- hardware details, but just info on whether you have to cmattach to the
- CM-5, etc.). Is the CM-5 supposed to be faster? I have actually
- recompiled and ran (without cmattach, as that didn't work) my code on
- the CM-5, and it was much much slower. I imagine I'm doing something
- wrong though. Maybe I'm not asking for enough processors or something.
- Anyways, if anyone has any clues on moving C* programs from the CM-2
- to CM-5, please email me at mlevin@jade.tufts.edu or
- mlevin@husc8.harvard.edu.
