Hi All, I am running R 2.2.0 on Mac OS 10.4.2, dual G5 processors with 8 Gig RAM. I am running a simulation with lsoda that requires ~378 s to complete one set of time intervals. I need to optimize the parameters, and so need to considerably speed up the simulation. I have tried to figure out how to change the appropriate memory allocation and have search R help and Introductory information and the archives, but connot figure out how to allocate more to the right place. I would greatly appreciate any pointers or tips or leads. Thank you, Hank Stevens Dr. Martin Henry H.

changing memory limits to speed up lsoda

Martin, For my simulations (same hardware with less memory). - Optimize the code : using Narray, avoiding loops - Installed distributed computations (PVM & RPVM tools are very easy to use, many thanks to Simon Urbanek for his help) Hope this will help Best Naji Le 26/10/05 16:43, ????Martin Henry H.
