Agree. I think the primary limitation is RAM, you have 16gb but
don't say how much you want to allocate to each instance of Stata
- that will most likely be your most immediate limitation on
the number of Stata processes running, though if they are all
CPU intensive they might run rather slowly.

I have a 16gb machine with 64bit XP, and the OS will let me
have a maximum of about 15gb.

Bulent,

I'm not sure what you're asking. It's certainly *possible* to run multiple instances of Stata under Windows. You can launch it as many times as you want. I've never noticed any problems resulting from doing so. If you're asking about whether Stata does its own record and/or file locking to protect against one instance of the program modifying a file that another instance is also reading or modifying, I think the answer is "no". If your programs are careful to stay out of each others' way, I don't think there would be a problem. (One question I have is whether you can count on multiple instances of Stata not creating temporary files of the same name.) As for the "optimum" number of jobs, I suspect that depends entirely on your purpose, your system, and how disk or cpu intensive your jobs are.

Dear Stata Users,

I was wondering if it would be possible/feasible to run multiple Stata
jobs by using the Windows version. I have a machine with the following
properties:
Inter Xeon CPU, E5430, 2.66 GHz, 16 GB RAM

Can I launch, say 8 Stata sessions at the same time? If this is
possible, how can I understand the optimum number of jobs possible to
run without getting stuck? Thank you for any help.
