–bsram ram_size
Specifies the amount, in megabytes, of block solver RAM the engine uses for equation solving. The value must be greater than 0.1. If you do not specify a value, or if you omit this option, the engine allocates 8 megabytes by default.

 The bsram and elram options have been superseded by the solram option. If you choose to use bsram and/or elram, you must specify them on the msengine command line, or by editing the mecbatch file. |
This allocation and the –elram allocation represent part of the memory the engine uses to run a design study. The engine dynamically allocates the rest of the memory it needs for the run.
You can use the default allocation for any run. If you have a lot of RAM on your machine, large models will run faster if you specify a higher RAM. You can slow the run substantially if you specify an allocation that is too large to fit in available RAM.
You can also slow the run if you do not specify sufficient space, especially if you specify less than the default.
As a general guideline for large models, set this value to one-half of your machine RAM if you do not use the -iter option, and to one-quarter of your machine RAM if you do use the -iter option. The optimal value also depends on other factors, such as what other processes are running on your machine.
