Do you know at what level this style of threading is implemented on MVS? Is each OpenMP thread a separate TCB or does this all happen within a single TCB?

z/OS XL C support for OpenMP, new in version V2R1, is built upon the POSIX standard pthread library, therefore it is not available on MVS, it is only available in USS where compiler runs POSIX(ON). The equivalent of MVS TCB is process in USS; openMP threads occur within the same process.
openMP support is only available in USS + 64-bit.
