Intel
Earlier this week, some individuals ready to take the bar examination obtained a message from ExamSoft, the corporate that makes the Examplify software program that many states use to manage the examination: PCs with Intel’s newest Twelfth-generation Core processors are “not at the moment supported” as a result of they had been “triggering Examplify’s automated digital machine examine.” The corporate’s steered resolution was that folks discover one other gadget to take the take a look at with, a irritating and unhelpful “workaround” for anybody with a brand new pc.
As identified by The Verge, Examsoft’s system necessities web page for its software program gives no extra element, merely reiterating that Twelfth-gen CPUs aren’t at the moment supported and that you simply aren’t allowed to run the Examplify software program inside a digital machine. However it’s not the primary time an issue like this has surfaced, and the offender is nearly definitely the hybrid CPU structure that Intel is utilizing in most Twelfth-gen chips.
In earlier generations, the entire cores in a given Intel CPU have been an identical to at least one one other: identical design, identical efficiency, identical options. Clock pace and energy utilization would ramp up and down primarily based on what the pc was doing at any given time, however the cores themselves had been all the identical and could possibly be handled that approach by the working system. In Twelfth-gen chips, CPUs include a mixture of fully totally different processor cores: giant, quick efficiency cores (or P-cores) deal with the heavy lifting, whereas smaller, low-power effectivity cores (or E-cores) deal with lighter duties. However as a result of working methods and most apps are used to assuming that every one CPU cores in a given system are the identical, software program has wanted to be modified to inform the distinction between the 2.
Apps that have not been up to date generally see the 2 various kinds of CPU cores accessible to them and assume that they’re truly seeing two fully separate PCs. This was the explanation why some online game DRM and anti-cheat software program packages wanted updates or workarounds to run on Twelfth-gen CPUs. Intel mentioned on the time that the affected software program was detecting the E-cores “as one other system,” which may additionally clarify why the Examplify software program thinks it is working in a digital machine—it sees that there is a layer of abstraction between it and the CPU, and it refuses to run.
That additionally means that there is a potential workaround that would make Twelfth-gen laptops appropriate with the Examplify software program within the quick time period: disable the E-cores. Not all PCs help this, however most custom-built desktop motherboards will allow you to do it, generally by adjusting the core counts manually and generally by enabling a “legacy recreation compatibility mode.”

Dell’s XPS 15 BIOS refers to E-cores as “Atom cores,” but it surely does help you disable some or all of them. This will likely not repair the Examplify subject, but it surely’s value a attempt.

The BIOS of the most recent ThinkPad X1 Carbon, alternatively, doesn’t seem to help you disable E-cores.

The choice is rarer in laptops, however at the least a few of the Twelfth-gen laptops we have examined thus far have a swap within the BIOS for it as nicely, often someplace within the efficiency or energy settings—we have included screenshots of a Dell XPS 15 BIOS that enables customers to regulate the variety of E-cores, and a Lenovo ThinkPad X1 Carbon BIOS that does not permit it. There isn’t any assure that disabling the E-cores will repair the issue, but it surely works for these older video games, and there is a good probability it would work for the Examplify software program, too (so long as you are able to do it within the first place).
Transferring to a hybrid structure has prompted different points, other than those with Examplify and older video games. Home windows 10 and older Linux kernel variations cannot take full benefit of Twelfth-gen processors as a result of they do not help the “Thread Director” expertise that Intel has constructed to make it possible for duties are being despatched to the CPU cores that may deal with them finest, forcing individuals with Twelfth-gen PCs to make use of Home windows 11 to get the very best efficiency and battery life. Disabling the E-cores has additionally been the one approach for some customers to make the most of Intel’s AVX-512 directions with early revision Alder Lake processors. As a result of these P-cores help AVX-512 and the E-cores do not, AVX-512 help is often turned off for all cores by default, however some motherboards will help you swap AVX-512 again on as soon as the E-cores are off (newer Alder Lake chips have had their AVX-512 capabilities bodily fused off, making the state of affairs moot).
