Re: In-depth tutorials on using ASMIDF?

Did send an email to Peter...with some documents I did write using that tool.

Re: Rif: Re: EXECUTE Instruction and location of its target instruction

Hi Steve, Thx for the input. Right. Yes, I know about the idea to have a macro to align to a 256 bytes boundary. Philippe

Re: Rif: Re: EXECUTE Instruction and location of its target instruction

Hi Paul, Thx much for the input. ref:Is LOCTR a help? Actually, I got nicely some infos from Martin T, about LOCTR possible use in such case, this can be found at http://www.pi-sysprog.de/free/makerel.html Philippe

Re: EXECUTE Instruction and location of its target instruction

Hi Abe, Very good point, about old processors. Thx much Philippe

Re: EXECUTE Instruction and location of its target instruction

Hi Steve, Thx for the additional infos relating some similar experience you got. Philippe

Re: Rif: Re: EXECUTE Instruction and location of its target instruction

Hi Aldo, Thx much for the input. Unfortunately I cannot for that project to implement Baseless processing therefore I cannot use EXRL instruction. Point is to keep the target of the execute is in a I-bank cache line, to be ok. regards Philippe

Re: EXECUTE Instruction and location of its target instruction

Hi Steve, Thx for your input, yes this is my understanding of the process. Philippe

Re: EXECUTE Instruction and location of its target instruction

Martin, Thx for the input. Unfortunately for current project I am working on, to convert old asm programs to Baseless processing is NOT an option, there is no time and no budget to :) . Later Philippe

Re: EXECUTE Instruction and location of its target instruction

Hi Rob, ref:It's in the same cache line or it's not. Actually this was exactly my point and I was confused about seen various coding approaches to reach that purpose to optimize as much as possible CPU use. later Philippe

EXECUTE Instruction and location of its target instruction

Hi, My understanding is, we should keep as closest as possible, the EXECUTE instruction and its target instruction...EXECUTE instruction being greedy enough in term of CPU use...to be clear dozens of Cycles needed to complete its execution. Reviewing old Assembler programs, I guess I am

Re: SIIS "issue" after upgrade to z13 machine.

Hi Pieter, Yes I did figure out that to use of MF=E/L or SF=E/L will help to avoid the SIIS scenario for IBM Macros. Thx much for your input have a good day Philippe

Re: SIIS "issue" after upgrade to z13 machine.

Hi John, Thx much for your input. Yes, I was planning to use newer instructions but I did realize seeing current design of the applications I am reviewing this will generate some extra needed time to be sure all is ok and I cannot afford this in current context. To implement Baseless pgm or

Re: SIIS "issue" after upgrade to z13 machine.

Apparently this is needed for some...sure SIIS is NOT new for sure, BUT performance issue was obviously revealed after upgrade to a z13, please do read documents referenced in previous updates. Have a good evening.

Re: SIIS "issue" after upgrade to z13 machine.

Hi Rob and Martin, Thx for your input. MY primary purpose is to detect SIIS scenarios across code I have to scan and to fix them. Code is not complicated I mean you do have basic i/o processing against files and some characters and numerics fields are processed. There are some Ex(ecute)

Re: SIIS "issue" after upgrade to z13 machine.

Hi Martin and Rob, First thx much for your input. Here are 3 links which relate the "issue" and common code for which we fall into a SIIS scenario: https://www.google.fr/#q=istream_flash_062606_v4

SIIS "issue" after upgrade to z13 machine.

Hi, As you may know, there is some kind of performance issue because of SIIS(Store Into Instruction Stream) after upgrade to a z13 machine in some scenarios. CPU increase of 30% can be seen in some case, so it may be good to perform to related changes to avoid issue from reoccuring. Did start
