However, possibly because of the foothold that the clone processors were getting in the market, there was decision to start charging for kernel software ... and my resource manager was selected as guinea pig. Also discussed here http://www.garlic.com/~lynn/2010e.html#25 HONE Compute Intensive which shipped in the middle of the vm370 release 3 time-frame. As mentioned in the above ... vm370 multiprocessor support was to go out in vm370 release 4 ... but design/implementation was dependent on lots of code in the resource manager. The initial policy for kernel charging was that hardware support would still be free (including multiprocessor support) and couldn't have prerequisite that was charged for ... as in my resource manager. The eventually solution was to move approx. 90% of the code from the resource manager into the "free" base ... but leave the price of the "release 4" resource manager the same (as release 3, even tho it was only about 10% of the code). for vm370 release 5, the resource manager was repackaged with some amount of other code ... including "multiple shadow table support" ... discussed here: http://www.garlic.com/~lynn/2010e.html#1 LPARs: More or Less? and renamed HPO (i.e. HPO was the charged for software that fit ontop of vm370 release 5). for vm370 release 6, the charged for software was repackaged, a full set of all the software (previously HPO) which was renamed SEPP ... and a subset of the SEPP software ... at a lower price that was named BSEPP. So neither SEPP nor BSEPP were free ... they were both kernel add-on software for the free vm370 release 6 base, that was charged for. When it came time for vm370 release 7, there was transition to charging for all kernel software ... and everything was merged back into single charged for kernel renamed VM/SP (and there was no more "vm370" releases). vm370 release 6 being free has been made available for Hercules (370 virtual machine on intel platform) ... but not any of the charged for software ... my resource manager, HPO, SEPP, BSEPP, vm/sp, etc. -- 42yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- 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
