2 gb size limit for ArcGIS 10.0 SP5 on 64 bit pc

[PaddyKoilkonda]

Can someone update me if there is any progress on 2gb size limit.

One of the applications that I run is custom built using spatial analyst tool (.NET & ArcObjects).

Although I run the applications on high spec pc's ( Multicore processors and 16GB memory on Win 7 64 bit ), it is very very slow (slower than running on a single processor) and is not using the available resources efficiently,

so my questions are as follows :

1  Does ArcGIS 10.0 recognise the additional cores.

2. Is there any progress with 2GB size limit

3. how to speed up the processing

4. has anyone encountered license issues on ArcGIS 10.0 on Win 7 64 bit pc ?

This sort of thing has been discussed on this forum in the past, a quick search threw up this thread.

Thanks and I am waiting for an update from ESRI if there was any progress since we are in 2014 and post technological advancements with high spec pcs - no progress yet in this case.

If you are looking for an official reply from ESRI, I would suggest discussing this with ESRI Tech-Support.

Paddy,

Here's some unofficial common knowledge answers that may help.

As you know ArcGIS 10 is a single threaded 32 bit application. At 10.0 SP5 most of the binaries are large address aware so they will have 4GB of address space available on a 64 bit operating system (the kernel does not share that space).

Background Geoprocessing was introduced at 10.1 SP1. The allows you to run geoprocessing tools as a separate 64 bit process. You may check to see if your arcobjects application can be rewritten as a GP tool to take advantage of this.

Esri is currently working on ArcGIS Pro, a 64 bit, multi-threaded application as a part of ArcGIS Desktop due to be released in the next few months.
