Possible bug between X86 processors?

BN
Beser, Nicholas D.
Sat, Jun 3, 2023 6:10 PM

I am working my way through the bootcamp 2022 tutorial, and I noticed something odd. It suggests that if I have different types of X86 processors, I may have issues in execution.

I was working with two different systems. A slower (6 core) VM system (genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the hello-world-with-cache-complete.py code on both systems. The VM system succeeded. The AMD system failed. In addition to the terminal output, I am including the output of lscpu. The question is: Do I build the AMD system differently? I recompiled the matrix-multiply routine thinking that it might have a problem with the executable, but I got the same error:

Here is the VM terminal dump:

Hi,

The question is: Do I build the AMD system differently?

gem5 does not need to be built differently on different host platforms.

build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2

occurred: Couldn't read magic bytes from object file

This error usually shows up if there is something wrong with the elf of the
binary that is being simulated (for example different ISA than the ISA gem5
binary expects). I wonder if you see the same error for other
binaries/programs on the AMD system?

I am working my way through the bootcamp 2022 tutorial, and I noticed
something odd. It suggests that if I have different types of X86
processors, I may have issues in execution.

I was working with two different systems. A slower (6 core) VM system
(genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the
hello-world-with-cache-complete.py code on both systems. The VM system
succeeded. The AMD system failed. In addition to the terminal output, I am
including the output of lscpu. The question is: Do I build the AMD system
differently? I recompiled the matrix-multiply routine thinking that it
might have a problem with the executable, but I got the same error:

Ayaz,

I use the AMD system as part of my computer architecture class. It has MIPS and RISCV compilers on it. I will make sure that the X86 gcc tools are also in place (I think it should be there). The VM system should have been setup the same way (I generated both MIPS and RISCV designs on the VM system.)

Hi,

The question is: Do I build the AMD system differently?

gem5 does not need to be built differently on different host platforms.

build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2 occurred: Couldn't read magic bytes from object file

This error usually shows up if there is something wrong with the elf of the binary that is being simulated (for example different ISA than the ISA gem5 binary expects). I wonder if you see the same error for other binaries/programs on the AMD system?

I was working with two different systems. A slower (6 core) VM system (genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the hello-world-with-cache-complete.py code on both systems. The VM system succeeded. The AMD system failed. In addition to the terminal output, I am including the output of lscpu. The question is: Do I build the AMD system differently? I recompiled the matrix-multiply routine thinking that it might have a problem with the executable, but I got the same error:

Ayaz, I use the AMD system as part of my computer architecture class. It has MIPS and RISCV compilers on it. I will make sure that the X86 gcc tools are also in place (I think it should be there). The VM system should have been setup the same way (I generated both MIPS and RISCV designs on the VM system.)

APL external email warning: Verify sender yazakram@ucdavis.edu<mailto:yazakram@ucdavis.edu> before clicking links or attachments Hi, The question is: Do I build the AMD system differently? gem5 does not need to be built differently on different host platforms. build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2 occurred: Couldn't read magic bytes from object file This error usually shows up if there is something wrong with the elf of the binary that is being simulated (for example different ISA than the ISA gem5 binary expects). I wonder if you see the same error for other binaries/programs on the AMD system? -Ayaz On Sat, Jun 3, 2023 at 11:12 AM Beser, Nicholas D. via gem5-users <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> wrote: I am working my way through the bootcamp 2022 tutorial, and I noticed something odd. It suggests that if I have different types of X86 processors, I may have issues in execution. I was working with two different systems. A slower (6 core) VM system (genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the hello-world-with-cache-complete.py code on both systems. The VM system succeeded. The AMD system failed. In addition to the terminal output, I am including the output of lscpu. The question is: Do I build the AMD system differently? I recompiled the matrix-multiply routine thinking that it might have a problem with the executable, but I got the same error: Here is the VM terminal dump: $ build/X86/gem5.opt ../materials/using-gem5/02-stdlib/complete/hello-world-with-cache-complete.py gem5 Simulator System. https://www.gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 22.0.0.0 gem5 compiled Jun 3 2023 10:44:14 gem5 started Jun 3 2023 13:50:32 gem5 executing on besernd1-vm5, pid 980747 command line: build/X86/gem5.opt ../materials/using-gem5/02-stdlib/complete/hello-world-with-cache-complete.py warn: The `get_runtime_isa` function is deprecated.

Ayaz,

I don’t have any other problems compiling binaries on the AMD system. I do notice that the VM system uses python 3.8.10, and the AMD system is using python 3.10.6.

I also see the same error with the precompiled matrix-multiply from the gem5 distribution. I don’t think it is due to the gcc compiler. It might be due to the version of python being used? I am open to any suggestions to debug this. I going to setup a virtual environment and install the older python to see if I still have this problem.

Nick

Hi,

The question is: Do I build the AMD system differently?

gem5 does not need to be built differently on different host platforms.

build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2 occurred: Couldn't read magic bytes from object file

This error usually shows up if there is something wrong with the elf of the binary that is being simulated (for example different ISA than the ISA gem5 binary expects). I wonder if you see the same error for other binaries/programs on the AMD system?

I am working my way through the bootcamp 2022 tutorial, and I noticed something odd. It suggests that if I have different types of X86 processors, I may have issues in execution.

I was working with two different systems. A slower (6 core) VM system (genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the hello-world-with-cache-complete.py code on both systems. The VM system succeeded. The AMD system failed. In addition to the terminal output, I am including the output of lscpu. The question is: Do I build the AMD system differently? I recompiled the matrix-multiply routine thinking that it might have a problem with the executable, but I got the same error:

Ayaz, I don’t have any other problems compiling binaries on the AMD system. I do notice that the VM system uses python 3.8.10, and the AMD system is using python 3.10.6. I also see the same error with the precompiled matrix-multiply from the gem5 distribution. I don’t think it is due to the gcc compiler. It might be due to the version of python being used? I am open to any suggestions to debug this. I going to setup a virtual environment and install the older python to see if I still have this problem.

APL external email warning: Verify sender yazakram@ucdavis.edu<mailto:yazakram@ucdavis.edu> before clicking links or attachments Hi, The question is: Do I build the AMD system differently? gem5 does not need to be built differently on different host platforms. build/X86/base/loader/image_file_data.cc:54: panic: panic condition sz != 2 occurred: Couldn't read magic bytes from object file This error usually shows up if there is something wrong with the elf of the binary that is being simulated (for example different ISA than the ISA gem5 binary expects). I wonder if you see the same error for other binaries/programs on the AMD system? -Ayaz On Sat, Jun 3, 2023 at 11:12 AM Beser, Nicholas D. via gem5-users <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> wrote: I am working my way through the bootcamp 2022 tutorial, and I noticed something odd. It suggests that if I have different types of X86 processors, I may have issues in execution. I was working with two different systems. A slower (6 core) VM system (genuine intel), and a AMD Ryzen 9 16 core processor. I tried to run the hello-world-with-cache-complete.py code on both systems. The VM system succeeded. The AMD system failed. In addition to the terminal output, I am including the output of lscpu. The question is: Do I build the AMD system differently? I recompiled the matrix-multiply routine thinking that it might have a problem with the executable, but I got the same error: Here is the VM terminal dump: $ build/X86/gem5.opt ../materials/using-gem5/02-stdlib/complete/hello-world-with-cache-complete.py gem5 Simulator System. https://www.gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 22.0.0.0 gem5 compiled Jun 3 2023 10:44:14 gem5 started Jun 3 2023 13:50:32 gem5 executing on besernd1-vm5, pid 980747 command line: build/X86/gem5.opt ../materials/using-gem5/02-stdlib/complete/hello-world-with-cache-complete.py warn: The `get_runtime_isa` function is deprecated.
