I think you are confusing SRB's with SRB's. (8-{]} The SRBs that are elligible for z**P processing existed long before the specialty processors did. They are called Enclave SRB's, and are pre-emptible, whereas normal SRB's are not. So, all the z**P processing does is now move the work off of GP's. The rules, other than where they run, have not changed. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
