General Question about the 'Best' Platform for NONMEM

I will be posting some results on NONMEM benchmarks in the next few days. It will be sent to nmusers and the sources put on the NONMEM ftp site run by Steve Shafer and Jaap Mandema. > One more thing. We have found a limit of 400 records under VM on the ESA 9000 > due to the loader not being able to go above 16 meg. Does anyone have any info > on number of records vs platform ? One scientist here wants to run a 600 record > problem. Can you be a bit more specific about what you mean by a record? The benchmark problem I have has been run on a variety of machines including PCs under Windows. It has 220 subjects and 1336 observations in total. There has never been an indication of a problem with the number of records. Are you referring to the number of records per subject? This has a default value of 50 (I think) and can be increase if necessary but it would require very unusual problems to have 600 records per subject! Can you give me (or nmusers) some better idea of what kind of problem you are attempting and what you mean by the number of records?
