(no output,...no gaps in above sequence) I also tried a much more complex test program that I wrote a while back, and it worked fine. It uses 6 SPEs to calculate a version of Reed-Solomon codes. It uses double-buffered DMA and mailboxes so I figured it might be a useful test: $ svn checkout svn://svn.code.sf.net/p/gnetraid/code/ gnetraid-code $ cd gnetraid-code/PS3-IDA/07-shebang $ make $ dd if=/dev/urandom of=400Mb bs=1M count=400 $ ./rabin-ida-ps3.pl split -n 5 -k 3 400Mb # splits file into 5 parts using Rabin's IDA $ rm 400Mb-0.sf 400Mb-4.sf # delete some "shares" $ ./rabin-ida-ps3.pl combine -o output 400Mb-*.sf # reconstruct file using remaining 3 shares $ cmp 400Mb output && echo files match files match That's maybe of no use, but I thought I'd test it anyway, fwiw. Thanks, dec
