Thread Safety

Some of our users are developing multi-threaded applications and so require thread safe library software. To address this need we have put substantial effort towards making our libraries thread safe. To date the C Library and the majority of routines in the NAG Fortran Library and NAG Library for SMP & Multicore are thread safe.

We would be very interested to hear from you regarding your requirement with respect to thread safety, and if you are using multi-threaded applications. Please send your comments to
