Sim without lending

The Simhive app always lends at least one thread, at the lowest priority; the browser lends nothing at all. What each way costs you.

Lending is how the pool stays fast, but how much you lend is up to you. The app always lends at least one thread; in the browser your PC lends nothing at all. Each way costs you something different:

The app, on one thread #

While the app runs, it always lends at least one thread: when you set Settings → This machine → Lend only 1 thread, while a game runs, and when your schedule says pause. That one thread is what keeps the pool alive, because there is always somewhere for a sim to go, yours included. SimulationCraft runs at the lowest priority Windows has, so your game, your browser and anything else on the PC always get the CPU first. With several cores, one thread at that priority does not show in a game in most cases.

Your own sims go to the pool, and off-peak they come back just as fast as anyone's: whoever sims when the pool is quiet gets all of it.

The cost is the queue at peak. When more jobs wait than the pool can run — raid night, everyone simming at once — jobs are ordered by what each member's machines gave over the last 30 days (how the score works). One thread gives little, so on a busy evening your Droptimizer waits behind the members who lend more. It is served, never refused, just later; a free allowance of about one Droptimizer keeps a newcomer's first sims from being stuck.

To lend nothing at all, quit the app and sim in the browser.

The browser, signed in, without a machine #

Sign in at https://simhive.app/sim with your token. While no machine of yours is connected to the pool, the page sims in your browser tab, on your computer — not on the pool. Nothing to install. The caveats:

• Much slower. Minutes where the pool takes seconds: a Droptimizer over all Mythic+ dungeons (about 120 items) took 20 minutes on a desktop CPU with 4 threads.
• Smaller sims only. A Droptimizer covers one source at a time: one raid on one difficulty, all Mythic+ dungeons, the delves, crafted gear, the world boss. Other sims take at most 40 items or points. Compare, Mythic+ routes, tank fights and upgrade tracks need the pool.
• Keep the tab open until the sim is done; your computer does all the work meanwhile.
• Chrome, Edge or Firefox. Safari cannot sim in a tab yet.
• Results wait 24 hours for a machine of yours to connect and put them in its History. Save report and Publish work from the browser meanwhile.

As soon as a machine of yours connects, your sims from the page go to the pool instead. More on the browser.

As a guest #

No token at all: open the sim page and sim. Everything from the section above applies, plus:

• Results last a day and go into no History.
• No publishing.
• 20 sims an hour from one address.

Get a token — free, and you are signed in right away — to keep your results and publish them.

Why lend more #

Lending more costs you little: Simhive drops to one thread by itself while you play, a schedule keeps it out of your evenings, and every batch it runs for the pool runs at the lowest priority. In return your own sims come first when it matters, on raid night, when everyone wants a Droptimizer at once.
