Instead of going through the hassle of creating a app_info for the new binary, why didn't you just rename the binary to the stock appname?

I didn't know you could do that. I thought that the client would be able to tell that the new app wasn't the correct app, and would reject it.

I have done some experimentation, and have got the new app working, with the app_info.xml file.

I have installed the file "pc_pentium4_sse2" and the app_info.xml file, and set the boinc permissions correctly. I changed all instances of gene_pcim to pc_pentium4_sse2 in the file.

It doesn't work, giving these error messages:
| TN-Grid Platform | Message from server: Unknown app name in app_info.xml | TN-Grid Platform | Message from server: Your app_info.xml file doesn't have a usable version of gene@home PC-IM.

I understand that the syntax in the app_info.xml file needs to be very precise, so I need help to correct my mistake.
This is the file I am trying to use, without any success. Where did I go wrong?
<app_info> <app> <name>pc_pentium4_sse2</name> </app> <file_info> <name>pc_pentium4_sse2</name> <executable/> </file_info> <app_version> <app_name>pc_pentium4_sse2</app_name> <version_num>100</version_num> <file_ref> <file_name>pc_pentium4_sse2</file_name> <main_program/> </file_ref> </app_version> </app_info>

Yes, I would like very much for an sse2 app that is compiled to work correctly on my Pentium M powered computer.
Which thread shall I look in for the link to download the modified app?

The application gene@home PC-IM v1.10 (sse2) doesn't work on my 32-bit Linux computer (Computer ID 54726).
It runs for about 15 seconds, then ends in Computation error (Exit status 193 (0xc1) EXIT_SIGNAL).
My /proc/cpuinfo file contains:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 2.26GHz stepping : 8 microcode : 0x20 cpu MHz : 2267.000 cache size : 2048 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss tm pbe nx bts cpuid est tm2 pti bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit bogomips : 4522.40 clflush size : 64 cache_alignment : 64 address sizes : 32 bits physical, 32 bits virtual power management:
so it does support sse2.

A typical Stderr output looks like:
<core_client_version>7.16.6</core_client_version> <![CDATA[ <message> process exited with code 193 (0xc1, -63)</message> <stderr_txt> Start @ Sun Aug 9 20:24:17 2020 SIGILL: illegal instruction Stack trace (7 frames): ../../projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux32__sse2[0x8072b8a] linux-gate.so.1(__kernel_sigreturn+0x0)[0xb7eecd14] ../../projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux32__sse2[0x804c974] ../../projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux32__sse2[0x80528ac] ../../projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux32__sse2[0x804b239] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf1)[0xb7be6e91] ../../projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux32__sse2[0x804b4a3] Exiting... </stderr_txt> ]]>

I am unable to tell what I have done wrong.
The non-sse2 app seems to work, but is probably a lot slower than the sse2 version.
