Here is a C:\ProgramData\BOINC\projects\www
.primegrid.com\app_config.xml example to enable multiple processor threads per task:
Code:
<app_config>
<app>
<name>llrGCW</name>
<fraction_done_exact/>
</app>
<app_version>
<app_name>llrGCW</app_name>
<cmdline>-t 4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>
</app_config>
I tested 1-, 2-, 4-, 7-, and 14-threaded tasks on 2x14 core Broadwell-EP with reg-ecc 2x4-channel RAM. 2 or 4 threads per task look to be the optimum for throughput, judging from average task durations. I am still waiting for more tasks to get validated in order to check throughput in credits/day. Processor time per task and credits per task are somewhat variable.
I guess the amount of processor cache, maybe in relation to RAM speed, play a role for the optimum thread count of the LLR applications.
