Yes, it's a scheduling bug. I'll make sure it gets fixed for 6.10.2. If you have more sparks then you shouldn't see this problem. Also, GHC HEAD is quite a lot better with parallel programs than 6.10.1, I'll try to get around to posting some figures sometime. Yes, I tried it with 3 sparks and it works,

Thanks for your help,

What does the code look like?

Simon : should we be start to try tthe HEAD for par stuff?

Please do - also I'm on the lookout for good benchmarks to add to nofib/parallel. Particularly programs that you think should speed up in parallel but don't - sometimes that helps us find bottlenecks in the runtime. Cheers, Simon
