Total Soviet Computing Power

SUMMARY

We have estimated the total computing power of the Soviet Union for both general-purpose and scientific explications. In general-purpose computing, the USSR hat the equivalent capacity of SOupercomputers, orf the total US general-purpose computing power. If used for sciesuifie computing, the Soviet computing inventoryapacity equivalentoray-I'l.or aboutf the total US scientific computing power.

To the Soviets, the aeqidsitieningle Western supercomputer wouldncrease in total scientific computing power. Acquisitioningleuperminicomputer would give the Sovietsiny increase in total capability,or either scientific or general-purpose computing. In terms of computational power per ruble spent, however, the Soviets certaMy will find it mghfy'attractive to actpdre Western computers of all classes. t

The large gap between the US and Soviet computing powersesult ofshortages of alt classes of computers in the USSR. TheSoviet ihortfall is particularly large for scientific computing, due to the absence of true supercomputers in the USSR. Although smaller computers can be used for scientific computing, they are very inefficient for demanding tasks such as advanced weapons system design. The Soviet Union will probably not be ready toarge-scale scientific computer comparable to theefore the.

Total computingioad. uveful concept It contains two important tub classes: general-purpose computing power, and scientific computing power. General-purpose coniputtnE includes word processing, industrial (eeord-keepiog. process control, accounting, and SO forth. The size of the computer system (above certain minimums) is iremienuy unimportant lor general-purpose computing Many users can effectively share one large system. Of they can each have his or her own small system.

Cone hnjons from the Inventory Approach: Depending oo Itow onccounts, the US leads by about two orders of magnitude in total computer power. The lead is greater in scientific computing than in general-purpose computing. In supercomputers, die Soviet! have essentially no systems"scientific" Soviet mac bines are the closest thing- The US lead Is relatively consistent across the whole range of computer types.nclude the most significant computers for genial-purpose and scientific applications in the US and the USSR. The broad distribution of systems which contribute to the bottom line total computing power marcs the results insensitive to etrees in individual numbers.

Personnel Amiroadi

An alternative way to estimate the total computer poweration is to take aof the computational resources at several scientific institutes, and scale that figure up tocountry.

The Budgetary method of estimation relies on published figures for the total Soviet inrescmeot in data processing equipment, along with the published costs for the Soviets tonil of computer power. The Statistical Abstract of the USSR (translated as The USSR in Figures) gives numbers for "Data Processing Eqmproent and Spare Parts" forime period. The IDC Processor Data Book gives similar figures for the US. (See Table 4)

Being generous to the USSR, one could allocate one quarter of their "Data Processing Equipment- budget to big mainframes, which contribute maximally to Soviet computer power. (Actually, the figure might be somewhat lower, since much of the computing budget has to be devoted to peripherals, mini- and microcomputers, and maintenance) For the US systems, we use the "large" sales column of Table 4 Those figures produce the following results for annual addition* to total computer power.
