RE: The system cannot execute the specified program

Dear Tom,
Dear All,

For those of us who prefer project specific NONMEM installations to save es=
timation time,
it might be helpful, if ICON can provide some rough guidance on the main co=
ntributor
to the RAM needs of NONMEM 7.
I.e. is it primarily the number of observations, compartments, thetas, omeg=
as, or
another variable or some function of these variables?

The following might be very cumbersome: Would it be possible to include a s=
witch
during the installation which disables certain NONMEM 7 features to save RA=
M.
(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 mino=
r issue.

Best wishes
Juergen

Pavel,

The message you describe is usually the result of not having enough memory =
available for the NONMEM 7 memory image. If you are using the "big" versio=
n of SIZES you may need about 1.6-2 GB of available memory for each job. F=
or the efficient use of NONMEM 7's new methods more variables are now stor=
ed in memory than was the case for NONMEM VI. The memory image is larger e=
ven if one is not using the new methods.
When using NONMEM 7 and the "reg" SIZES, I have been able to run 8 jobs sim=
ultaneously on a dual processor dual core machine, but only 3-4 jobs when u=
sing the "big" version of SIZES depending upon what else is running. I hav=
e 3 GB of memory and the task manager indicates a maximum of about 7.4 GB v=
ia paging.
