I am looking for a hardware, which must run about 256 computationally intensive real-time concurrent tasks in 24 hour mode (one multi-threaded C application). Each task takes about 40-50 MFLOPs, so all tasks require about 10 GFLOPs. CPU-RAM speed is insignificant. All tasks must be managed by a Linux Kernel (32 bit, with SMP).
I am looking for a one-mainboard solution with one multi-core CPU (if such CPU exist). If such CPU doesn't exist, then I need one mulit-socket mainboard solution (with multiple CPUs).
Can you please recommend me any professional CPU/Mainboard solution which will satisfy such requirements? It is also very important that there are no issues with Linux Kernel (2.6.25). No virtualization, no needs in huge RAM or CPU cache. I also would prefer Intel architecture and well-proved stability. I still have doubts that it is feasible at all.
Thank you in advance.
UltraSPARC T2 has 8 cores with 8 threads each. Integrated high-bandwidth memory and IO. The T5140 carries two of them for 128 hardware threads.
The theoretical max raw performance of the 8 floating point units is 11 Giga flops per second (GFlops/s). A huge advantage over other implementations however is that 64 threads can share the units and thus we can achieve an extremely high percentage of theoretical peak. Our experiments have achieved nearly 90% of the 11 Gflop/s. - (http://blogs.oracle.com/deniss/entry/floating_point_performance_on_the)
