Hi,
We have freeaxp installed on a hp hardware with 2 * dual core intel Xeon cpus and running Windows 2008 64 bit.
Tru64 5.1B is installed on the freeaxp instance and it is detecting only one cpu. On the windows task manager also we find only one of the four cores is being used by the freeaxp binary.

Need clarification on how to add more cores to the freeaxp instance.
The configuration utility provided for freeaxp does not seem to have any option to manipulate the cpu cores that can be allocated to the instance.

Thanks in advance
Elango

FreeAXP supports a single CPU. FreeAXP emulates an AlphaServer 400, a single core machine.

Elango,

this is the same with all available Alpha emulators. They emulate EACH Alpha CPU on ONE core. There are emulators, which emulate more than one Alpha CPU, but they just use ONE core for each inidual Alpha CPU emulated. The Alpha CPU emulation code is not multi-threaded (probably for perfomance reasons).

Only one core is allocated per instance. If running multiple instances under Avanti, the runtime system ensures each instance gets its own core.
