Question

More memory

Trying to solve a large linear algebra Ax=b problem using Prime.

The x:=lsolve(A,b) says not enough memory, but I can solve the same size using other software on my large 128GB of RAM.

Prime 11 reports in task manager as only 217 MB.

How do I give Prime access to more memory if possible?

Cheers

Prime 11 alone (with an empty sheet) consumes 127 MB on my machine. A problem of a random square matrix A 10000x10000 grows memory consumption to 800 MB. In general, to make memory free, close other programs.
Can you share the (lin solve) problem?

Or else, what is the size of your A?

 

Success!

Like I said can do this in other software, hoping Prime 11 & 12 can do in Prime?
