Greetings All, In Dr. Taylor's recent posting stating his improvements to the decoder performance in the WSJTX Development Branch release r4926, he stated that, "further improvements can probably be made by using more than one core concurrently, e.g., by using OpenMP".
I am using the the Development Branch release 4926 in a Ubuntu Linux environment, using the compiling techniques developed by Bill, G4WJS. In Ubuntu Package Repository there is a libgomp1 package... a GCC OpenMP (GOMP) support library. Would the performance improvements stated by Joe, K1JT, in his posting about using "OpenMP", be as simple as installing the Ubuntu libgomp1 package? I do use a i7-4770 CPU Machine, and even from my layman's perspective this might be overkill, by I do enjoy tweaking performance. I have been able to decode 12 signals frequently, and very fast, when all the required variables are in place. My radio's audio passband, and my WSJTX settings do limit my decode performance, but I always wondered if I could decode more signals if present in my passband/waterfall. In my setup, 12 decodes has like a "fixed" threshold that I can not get past. Thanks to all the developer's/contributor's to the excellent WSJTX software. WSJTX has given me countless hours of radio/computer/QSO enjoyment. I recently taught myself how to compile in Linux, and following the WSJTX development branch is much fun also. Truly, Sincerely, Thanks! 73, John, N1ISA ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
