New features in Version 26.6 of prime95.exe:

1. For rare cases where the program cannot figure out the number of cores and hyperthreading, the NumPhysicalCores option may help. See undoc.txt.
2. Faster FFT implementations are now selected for Core 2 CPUs with 1MB L2 cache or less (marketed under the Celeron and Pentium label).
3. New, slightly higher, trial factoring breakeven points.

Bug fixes:

• Occasionally, P-1 stage 2 would report 100% complete before stage 2 completed. This bug has been around forever. I've finally found the cause! Fixed in 26.5 build 2.
• Worktodo.txt was not updated properly when P-1 completed for a PRP test. Fixed in 26.5 build 3.
• In 26.5 build 3, when benchmarking and measuring CPU speed the program will keep all cores busy by launching auxiliary threads that loop indefinitely. This should prevent Intel Turbo boost from kicking in. This should prevent cases where the CPU speed is reported as 1.87 GHz, yet a benchmark reports very fast timings because the CPU core has been boosted to 3.2 GHz because only one core is active.
• In 26.5 build 3, the OS's mapping of hyperthreaded logical CPU numbers to physical CPUs is determined automatically at startup. The AffinityScramble setting (see undoc.txt) is no longer supported. It is replaced by the AffinityScramble2 setting.
• In 26.5 build 3, the message "set affinity to run on any cpu" instead listed all the CPU numbers and as well as CPU #31. Fixed in build 4.
• In 26.5 build 3 and 4, benchmarking a dual-core non-SSE2 machine will crash. Fixed in build 5.
• KeepPminus1SaveFiles=0 option described in undoc.txt did not work when a factor was found. Fixed in 26.6.
• The 32K,64K,80K length FFTs with sumout checking for Pentium 4's with 256K or less cache were not implemented. Symptom is a torture test failure. Fixed in 26.6.
• Prime95 does not load on Sandy Bridge CPUs running Win XP. I've got a trial fix in 26.6.
• Prime95 chooses very inefficient FFT implementations for Core 2 Celerons (they have 512K L2 cache). Working on a fix for for 26.6.
• Logical CPU numbers were sometimes output zero-based and sometimes one-based. In 26.6, they are all one-based.

New features in Version 25.7 of prime95.exe
-------------------------------------------

1) Time= in ini files no longer supported. A during/else syntax can be
unsed instead for some ini file options.
2) PauseWhileRunning enhanced to pause any number of workers.
3) LowMemWhileRunning added.
4) Ability to stop and start individual workers added.
5) DayMemory and NightMemory in local.txt replaced with a single Memory setting.
6) Memory can be set for each worker thread.
7) Scheme to distribute available memory among workers needing a lot of memory has been completely revamped.
8) MaxHighMemWorkers replaces delayStage2Workers option.
9) The executable now defaults to talking to the PrimeNet v5 server. To use the executable with the old v4 server, add "UseV4=1" to the top of prime.txt.

So hat Rightmark eine neue Version 3.58 ihres Memory-Test Programms RightMark Memory Analyzer veröffentlicht. Rightmark ist den Planet 3DNow! Lesern vorwiegend wegen ihres Audiotesters Rightmark Audio Analyzer ein Begriff, der in unseren Mainboard-Reviews Verwendung findet. Nun gibt's also weiteres Futter für die Overclocker und Systemintegratoren, die Stabilität ihres Systems auf die Probe zu stellen.

1) A bug was fixed where the torture test used more virtual memory than
necessary, sometimes resulting in an "Out of memory" error.

New features in Version 23.6 of prime95.exe

1) Several changes have been made to the torture test.
a) Machines faster than 1 GHz will use new test data that runs a lot more iterations. This will reduce time spent in initialization code,hopefully increasing stress on the CPU.

b) The torture test stops after 100 ILLEGAL SUMOUT errors.

c) There are now 3 flavors of torture testing. One that operates on small FFTs only, theoretically maximizing FPU stress. One that operates in place on large FFTs only, maximizing heat and power drain. One that runs a blend of tests using lots of memory, possibly catching errors that might only occur at a specific memory address.

New features in Version 23.4 of prime95.exe

1) Further performance improvements in the SSE2 FFT code. I've tried to
do more work while data is in the L1 data cache.

2) The program should now work with a "redirected proxy server". This was
done by sending full URLs in Primenet requests. While I don't anticipate
any problems, the old relative URL functionality can be had by setting
UseFullURL=0 in primenet.ini.

3) A bug in the assembly language add and subtract routines was fixed. The
bug could affect ECM on exponents just below
MAXIMUM_EXPONENT_FOR_FFTLEN - FFTLEN/2.

New features in Version 23.3 of prime95.exe
-------------------------------------------

1) Further performance improvements in the SSE2 code for FFTs larger
than 640K. You should see about a 4% improvement in LL tests on a P4. However,FFTs between 40K and 512K might be a tiny bit slower.
2) Stage 2 of P-1 factoring has been recoded for more speed. WARNING:
when continuing from a save file created in stage 2 by a previous
prime95 version, this version will restart stage 2 from the beginning.
ALSO: the stage 2 P-1 save file format has changed - in dual boot
scenarios you must upgrade mprime and prime95 at the same time

New features in Version 23.2 of prime95.exe
-------------------------------------------

1) Further performance improvements in the SSE2 code. You can expect about a 4% improvement.

New features in Version 23.1 of prime95.exe
-------------------------------------------

1) Big SSE2 FFTs now take the L2 cache size into account. P4 Celeron (128KB L2 cache) is faster for FFTs between 512K and 2M. P4 Northwood (512KB L2 cache) is faster for FFTs larger than 1M.
2) Benchmark no longer times 256K and 320K FFTs, but does time 2048K FFT.
3) Support for torture testing FFT sizes from 1280K to 4096K added.
4) A 900 MHz P-III is now required to get first time LL tests by default.
5) Slightly faster SSE2 FFTs for lengths of 5*2^N and 7*2^N (e.g. 640K, 896K).
