How to check 32bit spectre and 64 bit spectre

[helenpenghan]

I would like to check whether I am running at 32 bit spectre and 64 bit spectre. Could anyone tell me how to do so? And if I am running at 32 bit spectre, I wanna change it to 64 bit. How to do that also?
Thank you.

To test what version of Spectre you're using, use the following:
% spectre -debug3264 -V

To use 64 bit spectre, you can either:
- set the following variable:
setenv CDS_AUTO_64BIT spectre
- pass "-64" as a command line option to spectre

Regards.
