Cloud may be overpriced compared to on-premises systems

Cloud was the go-to choice for the past five years, but we could see 
traditional systems become more viable. Savvy architects consider all the

Irish data centers....an opportunity?

[Dave Jones]

Recently the BBC posted an article about how the grow in Irish data centers (or 
"centres" for the Brits) is causing a possible power crises. See "Can we make 
the internet less power-thirsty?" (https://www.bbc.com/news/business-64429819). 
Sounds like a great opportunity for IBM to highlight the sustainability of 
large numbers of Linux on z servers running on a z16 box. 
Hopefully somebody at IBM is taking a hard look at this now.

And the Brits seem to get it:
-
He points out that using the term "cloud" is highly misleading, as it is "a 
very physical thing".

The cloud does not float in the atmosphere, it consists of computer servers 
with a vast appetite for electricity.
The Irish example highlights how a combination of environmental concerns and 
worries about capacity in the grid have triggered a race to save the reputation 
of the data centre industry.

Re: Once upon a time......

Many thanks for sharing everyone's thoughts on this matter. I think that there 
are a lot of applications that could benefit from having access to the 
capabilities of a GPU or two (or ten:-), maybe not as a replacement or 
competitor for large Intel-based supercomputers, of course. Applications like 
data mining and ML have numerical requirement too, I believe.

Once upon a time......

[Dave Jones]

IBM was known for making some really nice scientific number-crunching systems. 
The 7090-7094, the S/360-195 and the follow-on s/370-195, the array processor 
3838 and the vector instruction set supported by the 30xx models come to mind. 
Over time, and with the rise of the Intel-based chips and their floating point 
capabilities, IBM decided not to pursue that market any more. 
Now I am wondering if, perhaps, the time is right for IBM to re-consider that 
decision. On modern z processors, we already have IEEE floating point 
instructions in the hardware, Linux (a popular options for Intel-base 
number-crunch systems), and support for PCI.e IBM is already allowing 3rd-party 
SSD drives to be attached and accessed by the o/s. What if we were able to 
connect a number, say, 40, of GPU cards (like the Nvida Tesla 1000) to a z box. 
Have the I/O system pass the GPU card directly an LPAR running on the system. 
Porting the CUDO drives over to Linux (or z/OS, or CMS for that matter) does 
not appear to be that difficult and the hardware changes should be transparent 
to the o/s. Linux already supports a large number of scientific. software 
applications, runs the latest versions of popular scientific languages 
(FORTRAN, C/C++, Python). I believe the IBM z would be well-suited to this, as 
the density of cards in the PCIe cages is far greater than the density that 
could be obtained in normal PCs. This, combined with the strong sysplex 
clustering ability of z/OS (or SSI on z/VM) could allow the system Z platform 
to pack more computing power into a smaller footprint than a comparable 
Intel-based Linux cluster system, while being easier to use as programs would 
not have to be rewritten to take advantage of the system's clustering. It might 
be an easy sell on it's energy-reduction assets alone, since everyone is now 
worried about how much energy data-centers now consume. 

Thoughts/comments/objections welcome, of course. Full disclosure: this idea was 
first suggested to me by Enzo Damato after his tour of the POK lab.

Celebrating 50 Years of Virtualization Innovation

[Dave Jones]

From Kerry Wilson at IBM:
August 2, 1972 was the day IBM officially announced VM as a product.   To help 
recognize the past 50 years of achievements and innovation by VM and the 
community I have created a few web pages in honor of the occasion:

 

IBM VM 50th anniversary - https://www.vm.ibm.com/history/50th/index.html
VM Timeline - https://www.vm.ibm.com/history/timeline.html
VM history and heritage (updated) - 
https://www.vm.ibm.com/history/index.html

 

Enjoy!

 

Many thanks to Max Campbell at the IBM Archives who supplied many of the videos 
and documents.  Thank you to Melinda Varian and Jim Elliott who both created 
remarkable historical accounts of VM and are linked on the third bullet above.  
If anyone wants to learn more those two documents are incredible.  I also 
wanted to acknowledge Bill Bitner, Lauren Maietti and Jacob Gagnon who put up 
with me talking about this the past few months and providing feedback along the 
way. We have some more planned, so please check back or subscribe for updates. 

 

Thank you!

A bit off topic here, but the IBM 407 lives on as the "spec" stage in the CMS

Hi, Enzo.
First, welcome to the wonderful world of IBM mainframes. I think you will find 
them fascinating as you discover their features and capabilities.
Since you appear to be somewhere in New York State, I would suggest that you 
attempt to attend the upcoming z/VM Workshop to be held at Binghamton 
University in Binghamton, New York on June 16-18. z/VM is IBM's premier 
mainframe hypervisor operating system that can support very large number of 
guests, including Linux and it will run on your new z114. The cost of 
registration for students is very low, only $10. You will need however to have 
a parent accompany you because of your age.
For more details, check out their web site:
http://www.vmworkshop.org/
Best of luck to you and please keep us informed as to you progress.
Take care.

Re: Use of zCX

[Dave Jones]

I agree with Robert's objections to zCX, and, frankly, If all a site wants to 
do is run zLinux applications on an IBM z system, it is much simpler (and 
perhaps cheaper) to just install z/VM on the box and then host as many Linux 
guests as you want. No extra external tooling is needed; just use out of the 
box management apps that are already available. Plus, the system programmers 
have much greater and finer, control over the hardware resources (memory, CPU, 
etc.) each zLinux guest is allowed to consume. And of course, z/VM and zLinux 
run very well on the full speed IFL engines, no other specialty engines 
required.  Connect the z/VM and z/OS LPARs together by hyper-sockets and you're 
good to go. 
If I was an z/OS shop looking towards Linux, that's how I would proceed.
Thought and comments always welcome.

Re: looking for 'how to' developing Rexx host command

From my notes:
Re: Calling PL/I from Rexx

Yes, that should work.

I would add NOEXECOPS to the main's options, to avoid the need for the
leading '/', as the '/' tends to get forgotten.

My personal preference is to specify:
*PROCESS SYSTEM (TSO);
PLIMOD: PROC (CPPLPTR)
OPTIONS (MAIN REENTRANT) REORDER;

DCL CPPLPTR PTR,
1 CPPL BASED (CPPLPTR),
3 CPPLCBUF PTR, /* MAPPED BY CBUF BELOW */
3 CPPLUPT PTR, /* MAPPING: SEE SYS1.MACLIB(IKJUPT) */
3 CPPLPSCB PTR, /* MAPPING: SEE SYS1.MACLIB(IKJPSCB) */
3 CPPLECT PTR; /* MAPPING: SEE SYS1.MACLIB(IKECPT) */

DCL 1 CBUF BASED (CPPL.CPPLCBUF),
3 CBUFLEN FIXED BIN (15),
3 CBUFOFFS FIXED BIN (15),
3 CBUFCMD CHAR (32767); /* ACTUAL LENGTH IS CBUFLEN - 4 */

DCL PARM CHAR (CBUF.CBUFLEN - CBUF.CBUFOFFS - 4) VAR
INIT ((SUBSTR (CBUF.CBUFCMD, CBUF.CBUFOFFS + 1,
CBUF.CBUFLEN - CBUF.CBUFOFFS - 4)));

so as to be able to write a TSO command processor.

In the above code, I've also included the declaration for PARM that will
give you the same effect as on your example, but without the 100 character
limit.

Good luck.

IBM’s Upcoming Z Series Chip Gains On-Chip AI Acceleration and New Name: Telum

In a major refresh of its Z Series chips, IBM is adding on-chip AI acceleration 
capabilities to allow enterprise customers to perform deep learning inferencing 
while transactions are taking place to capture business insights and fight 
fraud in real-time.

IBM unveiled the latest Z chip today (Monday) at the annual Hot Chips 33

that won’t follow a traditional numeric naming pattern used in the past. 
Instead of following the previous z15 chip with a z16 moniker, the new 
processor is being called IBM Telum (telum is Latin for javelin).

New versions of IPGATE and RXSCKET

[Dave Jones]

Greetings, all.  (This message will be of interest to the z/VM community, but I 
am posting here for completeness.)

Just in time for the first full day of summer, 2021 (at least in the Northern 
Hemisphere), there are now new versions of both IP{GATE and RXSOCKET. The 
highlights of there new versions are:

1) for RXSOCKET:

   support for the new TLS IOCTLs has been added, sockets can now be encrypted, 
queried, etc.

   support for IPv6 addressing

Just about anything that can be done by a C program using the new TCPIP library 
can be done by RXSOCKET

2) for IPGATE:

   support for IPv6 addresses

   support for TLS encrypted links

This is of course built on top of the new RXSOCKET module. You can now share 
SFS servers across z/VM systems securely and that ought to make the network 
security guys very happy.

There is also a working Rexx server and client based on IPv6 as examples, as 
well.Please drop me a note if you'd like to experiment with them.

Of course, this is still a work and progress and while it has been tested there 
might be problems that arise when 'out in the wild'. Let us know they you 
encounter anything.

Thanks again.

HLASM question about SQLITE3

[Dave Jones]

Hi, all.
I am now working with John McKown's port of SQLITE3 to z/OS Unix Systems 
services. However when I attempt to compile the SQLITE3A member with HLASM 1.6, 
I get errors that state:
 581 **OLDMKFUNC sqlite3_backup_
 582  MKFUNC sqlite3_backup_
010C 583+ DS 0F 
010C 0134584+ DC A(__$0022)

0114 586+ DC V(###0022) 
** ASMA224E No control section defined, external reference with GOFF option 
ignored - ###0021

Does anyone know how to correct this error?
Many thanks.

Re: FW: COBOL NJ

[Dave Jones]

Open Mainframe Project members and community,
We just announced today with support from Open Mainframe Project members 
Broadcom, IBM, Phoenix Software, Rocket Software, SUSE, Vicom Infinity, and 
Zoss Team, a series of initiatives to support the need for COBOL expertise in 
response to the COVID-19 crisis. Please see the blog announcement made below...
https://www.openmainframeproject.org/blog/2020/04/09/open-mainframe-project-helps-fill-the-need-for-cobol-resources
Please share the below social posts with your networks:
Twitter: https://twitter.com/OpenMFProject/status/1248327010268610572
LinkedIn: 
https://www.linkedin.com/feed/update/urn:li:activity:6654097221400829952/
As we all are members of the mainframe community, supporting each other in this 
time of need is critical. Each of you in the community has an opportunity to be 
a part of this by...
- posting your availability for volunteer or work-for-hire work for state and 
local governments and other critical organizations in need with COBOL in the 
'Calling all COBOL Programmers' topic on the OMP Community Forums ( 
https://community.openmainframeproject.org/c/calling-all-cobol-programmers/15 )
- providing your expertise to others that are working on COBOL systems that are 
responding to the COVID-19 crisis in the 'COBOL technical questions' topic on 
the OMP Community Forums ( 
https://community.openmainframeproject.org/c/cobol-technical-questions/16 )
Each and every one of us is a critical piece in helping overcome this global 
pandemic, and I know that the mainframe community is one to step up to the 
challenge. Thank you all for your dedication, and I look forward to working 
with you in this cause.
Thank you,
John Mertic

Re: Linux

[Dave Jones]

I would also suggest subscribing to the z/VM list as well:
 The IBM z/VM Operating System discussion

This IBM z/VM Discussion list is an ideal place to ask a question of your VM 
peers. Subscribers include VM customers, vendors, consultants, and IBMers, 
including z/VM Developers. (The IBM z/VM Operating System discussion was 
formerly known as VMESA-L)

To subscribe, send a note to
ibmvm-subscribe-requ...@listserv.uark.edu

In the body of the note, write only the following line in which you have 
substituted your name.

SUBSCRIBE IBMVM firstname lastname

To correspond with the list itself (e.g post to the discussion), use
ib...@listserv.uark.edu

View and search the current list and archives back to January 1994 via this:

Re: Software Delivery on Tape to be Discontinued

[Dave Jones]

Howdy, Steve.

I, too, as a student at TAMU in the early to mid 70s and what I remember was 
that it was an Amdahl 470/V6 that was delivered to the DPC (Data Processing 
Center, we Aggies are very literal about a lot of things). The day it arrived 
and was set up in the machine room, replacing the old IBM S/360-65, the 
center's director was none too pleased about the burnt orange skin color. He 
had the Amdahl CEs take the covers off, and out to the parking lot, where they 
were repainted Maroon with spray cans of  Rust-Oleum from the local hardware 
store.

Re: Linux (zLinux) on zSeries

[Dave Jones]

Hello, Munif.

First, welcome to the z/Linux community. A very good place top post such 
questions as yours is the "Linux on 390 Port " 
listserv. Instructions on how to subscribe to it or browse the archives can be 
found here:
http://www.vm.ibm.com/techinfo/listserv.html

Since you are interested in running Red Hat, the RedHat 7, installation 
instructions for installing it in an LPAR on z are in a chapter of this 
document:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/index

It has the step by step process you need to follow, and, of course, if you have 
any questions about something that's not clear, you can  ask on the LINUX-290 
list. Folks there are always willing to help out a newbie.

Good luck.

Re: curious: Popularity & use of C on z/OS.

[Dave Jones]

Hi, Paul.
Yes, using gcc390 requires a Linux system, either z/Linux running on the 
mainframe (in which case, the normal s390x gcc compiler is used), or Linux on 
Intel, using gcc in a cross compiler mode.

Re: curious: Popularity & use of C on z/OS.

[Dave Jones]

Hi, Paul.
I would guess that it is not, but since the gcc it uses is just the "normal" 
available gcc on a Linux distro, any updates to that are automatically used by 
the gcc390 process steps.Very handy to have if what you want to do is take some 
C code and get it ported over the the CMS envrionment.

and the problem is that LPARs L05 and L06 can not see FCTC devices 7302 and 
7303. they are both marked offline at IPL time. An attempt to vary them online 
gets a message that "no channel paths are available".
What am I missing here?

A COBOL bridge for Node.js

[Dave Jones]

Perhaps of some interest to the list

Have you ever wanted to just cut and paste some of that legacy COBOL code from 
mainframe applications into your latest Web application? No? Well, Romanian Web 
developer Bizău Ionică has developed a way to do just that, creating a COBOL 
bridge for Node.js, the JavaScript-based cross-platform runtime environment t

Enjoy.

DFSORT question....

[Dave Jones]

Hello, all.

I have a user here that has a question about DFSORT. Would this lust be the 
proper place to ask such a question or are there other lists that   would be 
more suitable?
Thanks and have a good one, too.

DJ

BTW, today is Texas Independence Day.

Re: DFSORT question....

[Dave Jones]

Thanks, Rex.

Here's the question:
---
I have tried samples from the DFSORT manual,, and can’t seem to find a method 
that works.. I am losing my mind ..

I have this simple sort JCL,, which works fine,,, I have not aligned the header 
yet,, but will do that later as I am adding fields …

Ihave attached the output from the run so you can see the results ..

All I want do, is this,, (add this column(s) to the report..) FROM THE outrec

multiply the time ,, in this case 14.59 like this .. (14*60) +59 to get total 
seconds

Then,, divide the Total I/O rate by the preciously calculated seconds, to get 
I/O rate..

Everything I have tried doesn’t seem to work ..

Any thoughts?

Re: ASM calling C or C++ subroutines

[Dave Jones]

You also may want to take a look at using the Creating and using persistent C 
environments section of the z/OS XL C/C++ Programming Guide. It documents 
how to call C functions from assembler in an efficient way. The assembler does 
not need to be LE-conformant, either.

Mad Men and the IBM 360

[Dave Jones]

A posting to the VM list from Billy Bingham:

I haven't watched Mad Men before, but while channel surfing last night I saw 
the opening sequence that featured a IBM 360. Not sure what model it was.

NBC News has this article on the 360 and Mad Men:
