How many cores?

How many cores?

How many cores will be available on the competition hardware? Will it be 40 cores with hyper-threading? The MTL lab seems to have a random collection of machines, ranging from 64 (assuming 32 core with HT) processors on the login node to between 40 and 32 on the test nodes.

For more complete information about compiler optimizations, see our Optimization Notice.

The MTL has 40 cores with 80 Threads. The configuration can be found on the MTL website and on the contest rules.

That is interesting. A call in Java to Runtime.getRuntime().availableProcessors(); returns different results on different runs. I see 40 and 32 on the testing nodes - never 80. I also see 64 on the login node. Maybe there is some additional factor, or java's availableProcessors() is not reliable?
