title = "A scalable PC-based parallel computer for lattice QCD",
abstract = "A PC-based parallel computer for medium/large scale lattice QCD simulations is suggested. The E{\"o}tv{\"o}s Univ., Inst. Theor. Phys. cluster consists of 137 Intel P4-1.7GHz nodes. Gigabit Ethernet cards are used for nearest neighbor communication in a two-dimensional mesh. The sustained performance for dynamical staggered(wilson) quarks on large lattices is around 70(110) GFlops. The exceptional price/performance ratio is below $1/Mflop.",

note = "Funding Information: We reportde on the status of our PC-based parallel computer project for lattice QCD (for more details see ref. [13]). Nearest-neighbor con-munication is implemented in a two-dimensional mesh using Gigabit Ethernet c,ards. This architecture presents a good compromisr, bet,ween computation and communication. The saturated sustained performances on large 1at)tices are around 0.5(0.8) GFlops/node for staggered (Wilson) fermions, which gives a price/perf(~rnlarIcr ratio better t,han $1.0(0.7)/Mflop.
