From the thread:
 
Welcome to World Kindness Day Challenge: 7 day PSP (Prime Sierpinski Problem LLR) from November 13 07:00 UTC to November 20 07:00 UTC

To participate in the challenge:
 

• Wait until the challenge timeframe starts (or set your BOINC Client download schedule accordingly), as tasks issued before the challenge will not count.
• In your PrimeGrid preferences section, select only the PSP (Prime Sierpinski Problem LLR) project.

Important reminders:
 

• Note on PSP tasks: LLR2 (the program PSP runs on) has eliminated the need for a full doublecheck task on each workunit, but has replaced it with a short verification task. Expect to receive a few tasks about 1% of normal length.
• The typical deadline for some of these WUs is longer than the challenge time-frame, so make sure your computer is able to return the WUs within 7 days. Only tasks issued AFTER the start time and returned BEFORE the finish time will be counted.
• At the Conclusion of the Challenge: We kindly ask users "moving on" to ABORT their tasks instead of DETACHING, RESETTING, or PAUSING. ABORTING tasks allows them to be recycled immediately; thus a much faster "clean up" to the end of a Challenge. DETACHING, RESETTING, and PAUSING tasks causes them to remain in limbo until they EXPIRE. Therefore, we must wait until tasks expire to send them out to be completed. Please consider either completing what's in the queue or ABORTING them. Thanks!

Let's talk about hardware:

Supported platforms for PSP tasks:

• Windows: 32 bit, 64 bit
• Linux: 32 bit, 64 bit
• Mac: 64 bit
• Multi-threading is supported and IS recommended. Click here to set the maximum number of threads.
• Uses fast proof tasks so no double check tasks are needed. Everyone is "first"!

Intel and recent AMD CPUs with FMA3 capabilities (Haswell or better for Intel, Zen-2 or better for AMD) will have a very large advantage running LLR tasks, and CPUs with AVX-512 capabilities (certain recent Intel Skylake-X and Xeon CPUs, AMD Ryzen 7000 and EPYC CPUs) will be the fastest.

LLR2 uses the most recent version of gwnum and supports all AVX-512 capabilities.

As with all number crunching, excessive heat can potentially cause permanent hardware failure. Please ensure your cooling system is sufficient. Please see this post for more details on how you can "stress test" your CPU.
 

Over here in Pacific Time I was able to get some tasks going right at the start.

Wow that’s very quick Bill. (AVX512)
