Even brand new systems from major manufacturers can have hidden flaws. System to ensure a high-load stress test environment.įrom the most recent ' stress.txt' file included in the download: Additionally, it uses all of the cores of a multi-CPU / multi-core Workload to test the stability of the CPU and the L1/L2/元 processor cache.

Since the software makes heavy use of the processor's integer and floating point instructions, it feeds the processor a consistent and verifiable Prime95 has been a popular choice for stress / torture testing a CPU since its introduction, especially with overclockers and system builders. Linux and FreeBSD versions can also be set up to run every time you restart your computer. You can monitor each of yourĬomputers' progress, even remote-control the work assignments they request using your userID's CPUs page!

Once you complete a workunit you can track your standings on theĬompetitive stats pages the server updates every hour (see Top Producers in the menu, left, for more stats). You can administer your account and computers on your userID's account page. Usually the program and PrimeNet know the best work to assign, but it's up to you! That's all you need to do! The program contacts a central server called PrimeNet to get some work to do. We recommend Windows users select Options » Start at Bootup or Start at Logon. Start the program! Linux and FreeBSD users should run the program from the command line with a -m switch, i.e./mprime -mĮnter your optional userID created on the website in Step 1, and optionally name your computer. Linux and FreeBSD users should use the standard tar and gzip decompression utilities. Other Windows users can choose from a variety of decompression programs. Windows 10, 8, 7, Vista, and XP have built-in unzip features. Unix and non-x86 users should check out Ernst Mayer's Mlucas pageĬreate a directory and decompress the file you just downloaded.

It's optional, but required to check your account details, computer status and performance statistics and to assign computers to your user ID.ĭownload the appropriate free program for your OS (see below for GPU software) and proceed to Step 3: Operating System If you have not done so, create your UserID. There are cash awards for discovering a new Mersenne prime! Joining GIMPS is usually as simple as downloading and running the program, answering a few questions, and the program does the rest. Improvements to the hyperthread core detection.

Faster factoring code using FMA if available.

The new code will now do multithreaded trial factoring.

Changes to default CPU cores assigned to each worker to optimize total throughput per system.

New benchmarking routines to determine the optimal FFT code.

Faster step 1 GCD for ECM and P-1 factoring.

For non-base-2 PRP tests, there is a new option to run each iteration twice and rollback if a mismatch occurs.

Because PRP tests are highly reliable, we now offer the option to do PRP tests instead of Lucas-Lehmer primality tests.

PRP tests now support a type of low overhead error checking that almost guarantees correct results even on flaky hardware.

Like LL tests, PRP tests now support shift counts to aid in running double-checks.

GIMPS has a new sub-project - finding (probable) prime Mersenne cofactors.

This replaces LL testing as the default work type

More robust implementation of Gerbicz error checking in PRP tests.

Modified torture test dialog box with new options and better understanding of the L1/L2/元 cache hierarchy.

See the readme.txt file for setting these options

Resource Limits dialog box to control Prime95's resource usage.

Eliminates the need for lengthy double-checking!!!

Warning: upgrading in the middle of P-1 stage 2 will restart P-1 stage 2 from scratch.
