Dear Tom, Dear All, For those of us who prefer project specific NONMEM installations to save estimation time, it might be helpful, if ICON can provide some rough guidance on the main contributor to the RAM needs of NONMEM 7. I.e. is it primarily the number of observations, compartments, thetas, omegas, or another variable or some function of these variables?
The following might be very cumbersome: Would it be possible to include a switch during the installation which disables certain NONMEM 7 features to save RAM. (I recognize that this might cause a lot of unpredictable software issues.) Dual CPU servers currently have around 8-18 RAM slots. 2 and 4 GB RAM chips are reasonably priced. Thus, on the 64-bit server side, this is probably a minor issue.

If you are using the "big" version of SIZES you may need about 1.6-2 GB of available memory for each job. For the efficient use of NONMEM 7's new methods more variables are now stored in memory than was the case for NONMEM VI. The memory image is larger even if one is not using the new methods. When using NONMEM 7 and the "reg" SIZES, I have been able to run 8 jobs simultaneously on a dual processor dual core machine, but only 3-4 jobs when using the "big" version of SIZES depending upon what else is running. I have 3 GB of memory and the task manager indicates a maximum of about 7.4 GB via paging. Tom Thomas M.
