25.2 Heap size

In principle 64-bit LispWorks can grow to almost 16TB but it is intentionally limited to a defined range in order to avoid clashes with other software as shown in Default range for 64-bit LispWorks heap.

Notes

Intel-based Macintosh

#x4000000000 to #x40000000000 (3.75TB)

 

PowerPC Macintosh

#x4000000000 to #x40000000000 (3.75TB)

 

Linux

#x4000000000 to #x7000000000 (192GB)

Effective limit around 160GB.

Windows

64-bit LispWorks is relocatable on all supported platforms as described in Startup relocation of 64-bit LispWorks.

In contrast, 32-bit LispWorks has a maximum heap size of 1.5-3.0GB depending on platform and is relocatable on non-Windows platforms only, as described in Startup relocation of 32-bit LispWorks.
