Hi Eliot

On Windows 7 Ultimate 32bit, on a laptop with 3GB RAM, tested in normal & Safe Mode your test maxed out around 1870MB using the Cog Spur v3018.

Hope this helps

Paul

here is the data from one of the runs: 62.2 78.2 94.2 110.2 126.2 142.2 158.2 174.2 190.2 206.2 222.2 238.2 254.2 270.2 286.2 302.2 318.2 334.2 350.2 366.2 382.2 398.2 414.2 430.2 446.2 462.2 478.2 494.2 510.2 526.2 542.2 558.2 574.2 590.2 606.2 622.2 638.2 654.2 670.2 686.2 702.2 718.2 734.2 750.2 766.2 782.2 798.2 814.2 830.2 846.2 862.2 878.2 894.2 910.2 926.2 942.2 958.2 974.2 990.2 1006.2 1022.2 1038.2 1054.2 1070.2 1086.2 1102.2 1118.2 1134.2 1150.2 1166.2 1182.2 1198.2 1214.2 1230.2 1246.2 1262.2 1278.2 1294.2 1310.2 1326.2 1342.2 1358.2 1374.2 1390.2 1406.2 1422.2 1438.2 1454.2 1470.2 1486.2 1502.2 1518.2 1534.2 1550.2 1566.2 1582.2 1598.2 1614.2 1630.2 1646.2 1662.2 1678.2 1694.2 1710.2 1726.2 1742.2 1758.2 1774.2 1790.2 1806.2 1822.2 1838.2 1854.2 1870.2 1886.2 974.2 62.2

The main difference here is fixes to memory segment allocation on Spur. Linux and Mac OS can now grow the heap to 2.9Gb or there abouts, and Win XP can grow to 1.8Gb. I'm interested in reports on other Windows versions that don't have XP's 2Gb user process address space limit.

Here's my test script: | them | them := OrderedCollection new. [[them addLast: (ByteArray new: 16000000). Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush] repeat] on: OutOfMemory do: [:ex| 2 to: them size by: 2 do: [:i| them at: i put: nil. Smalltalk garbageCollect]]. Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush. them := nil. Smalltalk garbageCollect. Transcript cr; print: (Smalltalk vmParameterAt: 3) / (1024*1024.0) maxDecimalPlaces: 1; flush

And the README is: CogVM binaries as per VMMaker.oscog-eem.779/r3018.

Rewrite memory allocation on linux for Spur. Arrange that the heap can grow above 2Gb without any large initial alloc.

Rewrite platforms/unix/vm/sqUnixSpurMemory.c to stand alone. Use it in place of sqMacMemory.c with Spur on Mac OS. Now Spur can grow the heap to 2.9Gb on both linux (CentOS 5.3) and Mac OS X (10.6.8).

Rewrite Spur memory allocation on win32 similarly to unix. Can now allocate up to 1.8Gb on Windows XP (which has a 2Gb address space limit). Add a flag to indicate if the win32 exe is running as a console app and don't write to the in-window console if so.

Fix some sign issues with free space tallying to allow Spur to shrink memory and answer via primitiveVMParameter heap sizes above 2Gb.

Add longPrintInstancesOf:/longPrintInstancesWithClassIndex: for debugging.

Suggest reading a suitable README when the linux VM fails to spawn the heartbeat thread.

Add parameter 54 on Spur to answer totalFreeOldSpace.

-- best, Eliot

Cool! CI's duly updated, and the latest build (http://build.squeak.org/job/SqueakTrunkOnSpur/16/) shows great improvement. It completes the entire test suite without crashing. I do see this:

sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory sqAllocateMemorySegmentOfSizeAboveAllocatedSizeInto mmap: Cannot allocate memory

and there are 45 failing tests, but that's significant improvement!
