Re: zAAP vs x64 performance comparison
1) zAAPs were only doing Java work. The z10 machines at the time had no option for zAAP on zIIP, so we're talking about real zAAPs here, which only are eligible for Java work. 2) Yes, when I said zAAP-eligible I meant just JVM work, not including stuff that isn't eligible. For example, if you look at the Websphere address spaces, the servants running the application Java code are almost all eligible. But the daemon, node agent and server all do more work that's not eligible. If you look in SDSF, there are a few data columns of interest: JOBNAME CPU-Time GCP-Time zAAP-NTime zACP-Time zAAP-Time ECPU-Time P3SR01AS 2189.2022.082039.81 6.72328.213225.14 P3SR02AS 7197.2465.006995.91 13.61 1125.679299.76 P3SR02A 1303.91 663.30 582.25 0.78 93.681303.91 P3SR02BS 7536.5365.277314.36 12.95 1176.919854.92 P3SR01A 516.91 106.61 381.86 1.47 61.44 516.91 P3SR01BS 1997.0914.321849.42 5.75297.582086.93 P3DMGR 5358.58 656.194511.57 30.37725.935358.58 P3SR02B 1314.07 649.79 603.67 0.92 97.131314.07 P3AGNTA 3111.00 418.392495.72 8.96401.573111.00 CPU-Time is the total normalized time across all the processor types. IIRC, ECPU-Time includes some enclave time that CPU-Time does not. GCP-Time shows the time on the GCPs. zAAP-NTime, is the zAAP time, normalized to the GCP speed, whereas the zAAP-Time column shows the non-normalized values. (Since those are different above, you can see I'm running on sub-capacity GCPs and the normalization factor is about 6.2x.) zACP-Time is the time on the GCP that was zAAP-eligible but for some reason ran on the GCP. You can see that 's very tiny. It will never be zero because of the way some interrupts are handled, but with IFAHONORPRIORITY=NO it can be very small. Note that NO is not appropriate in all situations. So when I said 95% of their zAAP-eligible time is on the zAAPs, I meant zACP / (zACP+zAAP-N). Here's an example though where it works out to 94% though: JOBNAMECPU-Time GCP-Time zAAP-NTime zACP-Time zAAP-Time ECPU-Time RTMSERVE 14639.67 7958.276564.75421.45 1056.30 14639.67 RTMSERVE3708.42 275.123392.55 8.20545.883708.42 That first address space spends a fair amount of time calling REXX scripts from the JVM, so there's more swapping backs and forth between the GCP and zAAP, and that's probably got something to do with why it has more zACP time. You'll also notice that ECPU-time = CPU-Time in this example, supporting my recollection that ECPU-time has something to do with the enclave time as there's no enclaves involved here. All this data is also in the type 30 SMF records. I'm glad you found the post interesting.

Question regarding sharing of CF
Martin, Below is a snippet from an e-mail my hardware sysprog sent after I had them turn on thin interrupts on our EC12 test/dev partitions CF engines. These CF engines are shared across 2 CF LPARs and I think you will like the results we are seeing. The results have been impressive. Looking at just one of the structures, DDV0_LOCK1, prior to the change, in an 8 hour interval during prime shift, we see a 6.5 microsecond response time for 1221K SYNC requests and a 288.4 microsecond response time for 6073 ASYNC requests. After the change we see for DDV0_LOCK1 a 4.5 microsecond response time for 2104K SYNC requests and NO ASYNC requests, meaning that all requests were satisfied synchronously. Now for the negative, which really is not a negative, before the change, over the prime shift the DEV CF processor utilization was 0.6% busy, after the change its now 35% busy. With the improved performance that we are seeing in response times for our DEV environments I think it's well worth it.

It deletes _every_ DSN (with some exceptions such as SYS1 and others in a customer supplied exclusion list) which the internal control blocks (SWA) says that the job is going to try to create. It runs as the first step so that it can scan the SWA. It checks for DSNs which the job is going to try to create (regardless of disposition of CATLG, DELETE, or KEEP) and actually, internally, uses IDCAMS DELETE to delete them in the first step. At least as I understand what I was told by one of the writers of the package. One reason for this exclusion list was the number of people who would mess up their JCL so that the DISP was missing or the JCL converter/interpreter would comment it out. This saves critical DSNs from being deleted. IIRC, it was done after a sysprog had a JOB with SYS1.LINKLIB (to which he had ALTER access) in a DD and simply forgot the DISP. Bye-bye to SYS1.LINKLIB. And then, soon thereafter, bye-bye system. Or does it modify control blocks for the remainder of the job? Well, if the job is a restart, it will mess around with the relative GDG numbers properly so that the restarted job will actually restart in the failing step. It also updates internal control block from the data base it maintains in order to post the previous run's return codes into the proper control blocks in the current run with the values from the previous run, then bypass those steps so that they don't actually run. This way, any COND= and IF statements would work just as they would have in the previous jobs, had it not abended.

SYSGENs were many-step jobs; and they often failed, not least frequently because the space required in some [real] DASD dataset had been underestimated and that available had been exhausted. IBM provided a utility for reconstituting a job beginning with step n 1, but it was appropriate indeed essential to delete many already allocated DISP=NEW datasets before rerunning it.

z/OS SMTP server
I am writing a simple CICS application to use the EXEC CICS SPOOL commands to write data to JES to be used by z/OS SMTP (not CSSMTP which we do not have running). My question is simple, but perhaps the answer is not. The question is, what is the best way to get the correct domain name to be used in the SMTP HELO command? We have quite a few batch processes that use the z/OS SMTP server to send email. All of them appear to just have coded HELO ZOS. While this works, it also is not technically correct because ZOS is not in fact the domain name. Rather, in our DEV LPAR it should be zosd.fb and in production prd1.fb. So we have a lot of the following the the SMTP LOGFILE DD: EZA5460I 09/02/14 09:01:24 BSMTP Helo Domain: ZOS I've never heard of you! rather than the more desirable: EZA5460I 09/02/14 12:23:11 BSMTP Helo Domain: zosd.fb Yours too, I see!

Re: z/OS SMTP server
In our shop we have a started task called SMTP which is associated to a JES output class. That started task's cataloged procedure calls PGM=MVPMAIN with a CONFIG DD reading a certain statement for NJEDOMAIN. I think this is the SMTP setup not CSSMTP. You might check this in your environment. I am pretty sure, your NJEDOMAIN reads ZOS. The interesting point is *not* to set up an NJE node or even network (I think you can do but that's another story). Here, the NJE domain name is used in the default set of rewrite rules for the RFC822 header fields. For us this is a good (or correct) setup when for example we IEBGENER our memos to the JES output class associated with SMTP. We just write HELO ZOS and our SMTP started task will forward the correct way to our Lotus Domino service including query of MX records and all that stuff.

My question is simple, but perhaps the answer is not. The question is, what is the best way to get the correct domain name to be used in the SMTP HELO command? We have quite a few batch processes that use the z/OS SMTP server to send email. All of them appear to just have coded HELO ZOS. While this works, it also is not technically correct because ZOS is not in fact the domain name. Rather, in our DEV LPAR it should be zosd.fb and in production prd1.fb. So we have a lot of the following the the SMTP LOGFILE DD: EZA5460I 09/02/14 09:01:24 BSMTP Helo Domain: ZOS I've never heard of you! rather than the more desirable: EZA5460I 09/02/14 12:23:11 BSMTP Helo Domain: zosd.fb Yours too, I see! SMTP doesn't seem to really care. Other than the message above it still works no matter if you supply the correct domain or not. I looked at the source code for the SMTPNOTE CLIST and see that even there the value is hardcoded. Do we just need to make this somehow configurable and make sure we configure it with the name of the LPAR the CICS is running in? Seems a bit of overkill. Honestly, the whole requirement for a user application to actually specify SMTP commands seems to me to be more than a little crazy. And in any case, the requirement for specifying who I am on the HELO is even odder. Especially since (for example) the Microsoft Exchange SMTP server doesn't even require it: 220 ES05.firstbank.fb.ent2 Microsoft ESMTP MAIL Service ready at Tue, 2 Sep 2014 12:39:56 -0600 HELO 250 ES05.firstbank.fb.ent2 Hello [10.100.5.50] whereas the z/OS SMTP server does require it. When not present the email is not sent and the SMTP log shows: EZA5465E 09/02/14 12:48:53 Deleting Spool File from undetermined origin job number (JOB04887) Perhaps in the end I'll just use HELO ZOS just like every other email job we have. But I like to have things as correct as possible (when possible and not a huge amount of extra work).

Re: z/OS SMTP server
Right, LPAR name is not automatically set in a static symbol. I guess in nearly 20 years of sysplex we've never needed Rexx access to that name. However, it would be a simple matter to set an installation symbol like this in IEASYMxx: SYSDEF LPARNAME(lpar-name) /* For this LPAR */ SYMDEF(pppLPAR=lpar-name) /* Set installation symbol */ where 'lpar-name' is the name of an LPAR and 'ppp' (optional) is an installation-specific prefix used in all locally defined symbols. I recommend using the SHARE installation code here. There would be one pair of such statements for each LPAR that shares IEASYMxx. In a Rexx, MVSVAR(pppLPAR) would return the name of the current LPAR. . .

Re: Demonstrating Moore's law
Robert Wessel robertwess...@yahoo.com writes: That number is certainly too low. EC12s have 1-4 books, each with six processor chips (yes that comes to 144, only 120 can be used), and anyone not buying a configuration topped out for the number of books installed will have more chips. BC12s have either one or two chips. On both models the revenues for the sub-capacity models is significantly less on a per-processor chip basis than your calculation would imply (nominally a EC12-401 is about $840K, while a 89-times faster single book -720 with the identical number of processor chips is $10.8M - the BCs have even worse ratios). Also, you're assuming list prices for full function CPUs (if you're buying IFLs, zAAPs, zIIPs, ICFs, etc., they're cheaper). So the real number is likely several times higher, probably around an order of magnitude. Another way to do the calculation is to assume that the 10,000 machines in existence are replaced every three years. Even if those were all maxed out EC12-7A1s, that's only 120,000 chips per year. And while neither that replacement rate or the machine size is remotely realistic, it puts a hard upper cap on the number of dies to be produced for sale in machines. Perhaps a more reasonable assumption would be a four year replacement cycle and an average of ten processor chips per box, which gets you 25,000 chips/year. In any event, that doesn't help IBM's costs any. The total manufacturing costs for those chips is minuscule, and the NREs still have to be spread over the same revenue base. re: http://www.garlic.com/~lynn/2014j.html#85 Demonstrating Moore's law http://www.garlic.com/~lynn/2014j.html#86 Demonstrating Moore's law http://www.garlic.com/~lynn/2014j.html#87 Demonstrating Moore's law IBM mainframe processor financials had been doing about $4B-$5B annum for a decade or so (but that number has dropped recently). A much bigger revenue number for IBM mainframe group has been the software, services, and storage it sells (total mainframe group revenue has avg. a little over 6times its processor system revenue, and is extremely profitable being as much as 40% of total company profit). assuming that max configured systems work out to have the best price per processor ... and max configured systems running around $30M ... ibm has been selling the equivalent of 133-166 max. configured systems per annum for a decade or so (but recently dropped to less than half that) aka if there are a larger number of smaller systems, assumption is that the price/processor would be higher, and fewer total processors and therefor chips ... using max configured systems equivalents would tend to put an upper bound on total number of processors/annum). At the upper limit, the previous decade would have been the equivalent of 1660 new max. configured systems (@166/annum) ... and 1st qtr 2014 mainframe processor numbers on annualized basis is 56 max. configured ec12 systems. so instead of 120processors in (@6processors/chip, 20chips) ... say ec12 actually has 240processors (although only max 101 are directly configured) that would make it 40chips @56systems/annum that is 2240chips/annum ... remapped to 14nm technology and 450mm wafers that is less than 2 wafers (@1383chips/wafer), rather than less than one. If the aggregate mainframe chips that are less than couple dozen wafers (or as few as one) in production fab mostly used for other things ... then the fab costs are amortized across the other chips ... and the mainframe chips are nearly incidental. However, if the fab had to recover the total technology costs just from mainframe sales ... it would be quite a bit more expensive. that is major reason that mainframe has migrated to being built using mostly industry standard technology, industry standard disks, industry standard fibre channel, industry standard chip process, etc. -- virtualization experience starting Jan1968, online at home since Mar1970 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Announcing PCRE Pert for Classic z/OS 8.35 (Build 1499)
Announcing PCRE Port for Classic z/OS 8.35 (Build 1499) PCRE Port for Classic z/OS (Perl Compatible Regular Expressions) is now on a regular maintenance schedule, lagging only few months behind the main PCRE package version. The port is working with well defined scripts with minimal manual intervention. The port is available on my site http://zaconsultants.net/ and hopefully soon on http://www.cbttape.org/. The core documentation for PCRE is found as usual in http://www.pcre.org/pcre.txt . The Port documentation is part of the download file here www.zaconsultants.net/pcre_native_zOS_port.8.35.1499.zip The port includes the source code, JCL, LKED parameters, etc. and instructions on how to build it on any run-of-the-mill z/OS environment as well as XMIT formatted libraries (PDS and PDSE) that include the above, plus executables on a load module library that was compiled with codepage IBM-1047. The port is for classic z/OS. I know it would compile and work on z/VM, but the z/VM official support has been dropped. 1. While a few people have expressed interest in the PL/I interface and some tried to give me useful advice, I've found that with my limited time and resources, I cannot do it. Hence, PL/I support is officially dropped and will not be renewed unless there would be a volunteer who is both capable in working with PL/I and its interfaces, and is ready to devote time for this project. 2. Rexx seemed to me to be a perfect fit for PCRE. It is analogous to Perl in the native z/OS ecosystem and is doing similar (though much more primitive) pattern matching. However, the Rexx interface is extremely involved and working with it requires expertise that I do not posses and do not have the time to acquire, and that despite of useful advice from some people. Hence, no Rexx support is planned unless there would be a volunteer who is both capable in working with Rexx and its interfaces, and is ready to devote time for this project.
