Hi Andi,
I have question related to running a wrapped function in a
multithreading/multiprocess environment in python.
We have a java library and we wrapped it using JCC so we can call it from
python.
We have a list of data that we need to call a wrapped function for each of
the data in the list.
Everything works fine when we call it in a single threaded env but the
process is slow as it's sequential. Now we are trying to speed up the
process by calling this function on multiple thread.
I tried to call the initVM on the "main" thread then on each of new thread
I will call attachCurrentThread (begin) and detachCurrentThread (end).
This doesn't seem to work properly as we getting some weird VM issue.
Please explain what "some weird VM issue" is. How can I help you otherwise ?
What is the best way to do multithread using JCC?
What you're doing seems correct, iirc.
Andi..
Thanks,
Chee Yong
