1) Message boards : SETI Perspectives : What to Expect from ET? (Message 2009808) Posted 29 Aug 2019 by Henry Pfeil Post: We have yet to figure out how exactly a single-celled organism arose from the primordial soup. In a drop of pond water, I have seen a ball of protoplasm whip its flagellum flying around like a helicopter, an amoeba envelope a bit f food and pop it inside its cell wall. We have no clue how a living cell arises from nothing, capable of replicating itself, hunting for or creating nourishment (out of sunlight!). If we find ET elsewhere, we can circumvent all those questions of life origin. If intelligent life arose on a different planet, we will know that the process of a first cell wall surrounding a single living organism is not unique to this planet. We will no longer have to concern ourselves with the uniqueness of a first single celled living being arising from nothing, it will become suddenly a common occurrence that can happen anywhere the same environment exists. Dr. Drake's Equation will then become relevant, once ET demonstrates the underlying assumption that living beings arise anywhere there are favorable conditions is proven correct. ET where are you?

2) Questions and Answers : GPU applications : Radeon Vega vs Astropulse on Linux (Message 2007886) Posted 17 Aug 2019 by Henry Pfeil Post: I apologise for posting in the wrong forum. This URI is setiathome.berkeley.edu, nothing that would lead me to suspect this was a BOINC forum. With "AMD/ATI" no longer supporting Linux, I had to do a lot of digging to find out why the AstroPulse wu hangs, taking up a processor slot with no progress. I'm merely reporting my findings here. Had I access to the source code, perhaps I could help with migrating the OpenCL code to Mesa. Thank you for your kind suggestion offering contact information of which I was unaware. I appreciate your help!

3) Questions and Answers : GPU applications : Radeon Vega vs Astropulse on Linux (Message 2007736) Posted 16 Aug 2019 by Henry Pfeil Post: OpenCL Mesa 1.19.2, AMD RAVEN (DRM 3.27.0, 4.19.62, LLVM 8.0.1) Astropulse work units hang because they try to compile the OpenCL Kernel. I can compile openCL programs written in C with an openCL kernel, so I have to ask why Boinc cannot compile an Astropulse openCL kernel. I use gcc –lOpenCL or g++ -lOpenCL The AstroPulse v7 READ...opencl_ati.100 proudly proclaims: "It is mandatory to have the AMD Catalyst fglrx driver for linux" There is no AMD Catalyst fglrx driver for linux. This obsolete fglrx driver fell by the wayside when AMD absorbed ATI. The fglrx driver is for older ATI graphics cards (2008-2014?). The Linux Kernel includes the amdgpu module. According to the Khronos CL spec, you can look in /etc/OpenCL/vendors where on my computer you will find mesa.cl, with the single line: libMesaOpenCL.so.1 The Kronos site https://github.com/KhronosGroup/OpenCL-ICD-Loader contains the official OpenCL ICD Loader that links /usr/lib64/libOpenCL to the library contained in the vendors file. I'd like to process work units from AstroPulse using my "AMD Ryzen 5 2500 cpu with RadeonVega Mobile Gfx", but I can not until you update your software to Khronos OpenCL standards. Abandon, Ye, the fglrx driver! I wrote a wrapper for AstroPulse_Kernels_r2751.cl compiled it an ran tests using your kernel. Would that AstoPulse would do the same.
