Microsoft, in general, still seems unaware of the seriousness of the issue. I believe that they feel that no one would ever create such a large object. The technical computing guys get it but they can’t promise a fix. It could be years, unfortunately.

Internally, we have gotten around this problem by creating memory on the native heap inside our data structures. We have created a custom LU factorization for a customer and underlying matrix, vector. All were long indices with native data arrays. It all worked flawlessly.

We hope to have a version of the product in the future that uses the native heap. Stay tuned.

Any furhter update on this? 2GB limit on 64-bit systems is restricting. Large engineering simulations can easily have 100,000+ equations. Thanks.
