This group is for all folks running the original IBM VM/370 Release 6 operating system (or later (e.g. VMTCE (Community Edition)) on Hercules. Like the other early IBM operating systems this version has always been in the public domain and so can be freely distributed. The base version as supplied by IBM is lacking in many facilities. IBM solved this by providing additional extension products which were licensed and so are not available. There are however many user enhancements available which can be installed. In addition, in order to get users up and running quickly updated "releases" of VM/370 included the most popular updates are available for download, so novices can start to learn VM without having to delve into the system internals. It is intended that this wiki will provide information on the base release and these updates.
The available versions are here :-

Re: AP and/or MP support in VM/CE: Does it exist or no?
Hi, At OCF, we used our AP strictly for compute bound programs. I was at the research facility and users we doing fluid dynamics of fire, wind, cold air, hot air, etc, we had need for an AP. I take it

Re: AP and/or MP support in VM/CE: Does it exist or no?
My recollection (fuzzy as it may be) is that MPs were available before APs. (The hardware, I mean, not the OS support.) Of course the 360/65 had an MP option, but it was architecturally a bit

Re: AP and/or MP support in VM/CE: Does it exist or no?
Jay, MP support was not available until VM/SP. Mark's port details the reasons that AP support is so poor in VM/370; he is correct. Regards, Bob

Re: AP and/or MP support in VM/CE: Does it exist or no?
I also worked in a shop that had a 158, and upgraded it to an AP, with a total of 6 MB of main storage (4 MB was Memorex add-on memory).? It also worked well for MVS.? IIRC, it also worked

Re: AP and/or MP support in VM/CE: Does it exist or no?
OK, so I'm curious. MPs were available at the same time asAPs, IIRC. Was MP support strictly a VM/HPO feature? Base MVS 3.8 works on AP/MP systems just fine. My first sysprog job was on a 370/158AP

Re: AP and/or MP support in VM/CE: Does it exist or no?
AP support is available in VM/370? (not MP), but I wouldn't recommend bothering with it.? Because of the limitations where the attached processor cannot do i/o, it forces a lot of extra overhead

Re: AP and/or MP support in VM/CE: Does it exist or no?
Bert I think I will also say that, whilst an AP version of VM might be ¡°nice to have¡± it doesn¡¯t add any function. Fixing it requires effort that could be directed towards fixing other things or

VM/379 has no MP support. OK, why would AP support be nice? Details, please. Bob Bolch wrote:

Hello Chris, Thank you. My point is simple: For new people who are looking for Hercules (such as myself) it looks like Google is going to the www.hercules-390.org website before the 4.4.1 on Github.

Bertram, http://www.hercules-390.org ( http://www.hercules-390.org/ ) is an old website for Hercules, and doesn't have any support beyond 3.07. For Hercules 4 (hyperion) onwards, the current website

Re: AP and/or MP support in VM/CE: Does it exist or no?
Hi Dave, Updating the AP code and adding MP might be nice. I'm assuming (oh, yeah, I know what that can mean) Hercules supports multiple processors (e.g. sockets and cores). If so, it would be nice
