### Tab 1: Supercomputer Allocation Policy - **Baseline Allotments**: Tier-1 research proj… — GMAT

### Tab 1: Supercomputer Allocation Policy
- Baseline Allotments: Tier-1 research projects receive a baseline allotment of $500$ node-hours per calendar month. Tier-2 research projects receive a baseline allotment of $200$ node-hours per calendar month.
- International Collaboration Incentive: If a project includes verified international co-investigators, its monthly allotment is increased by $50\%$ , provided an approved Ethics Waiver is on file before the start of the billing month.
- Overflow Billing Rule: Usage exceeding a project's monthly allotment is billed at a surcharge rate of $\$15$ per node-hour, unless the overflow hours occurred during designated off-peak hours ( $00:00$ – $06:00$ UTC). Off-peak overflow hours consume backup priority reserves without monetary penalty, up to a maximum of $100$ off-peak overflow hours per month.

### Tab 2: Project Profiles & March Usage Logs
- Project Quantum: Tier-1 status; International Co-investigators: Yes; Ethics Waiver Filed: January 15; March Total Usage: $780$ node-hours (comprising $180$ off-peak hours and $600$ peak hours).
- Project BioGene: Tier-2 status; International Co-investigators: Yes; Ethics Waiver Filed: March 12; March Total Usage: $260$ node-hours (all during peak hours).
- Project AstroPhysics: Tier-1 status; International Co-investigators: No; Ethics Waiver Filed: February 10; March Total Usage: $540$ node-hours (comprising $40$ off-peak hours and $500$ peak hours).

### Tab 3: System Administrator Operations Log
- Peak vs. Off-Peak Definition: Peak hours are $06:00$ to $23:59$ UTC daily; Off-peak hours are $00:00$ to $05:59$ UTC daily.
- Waiver Deadlines: To modify March allocation limits, required compliance documentation must be submitted and approved no later than $23:59$ UTC on February 28.

Consider each of the following three statements regarding March usage:

1. Project Quantum incurs monetary overflow penalties for its March node-hour usage.
2. Project BioGene's modified baseline allotment for March is $300$ node-hours.
3. Project AstroPhysics exceeded its allowable March baseline allotment by exactly $40$ node-hours.

Based on the information provided across the three tabs, which of the following options correctly classifies the truth value (Yes = Accurate, No = Inaccurate) for Statement 1, Statement 2, and Statement 3, respectively?

Statement 1: No; Statement 2: No; Statement 3: YesAnswer
B
Statement 1: Yes; Statement 2: No; Statement 3: Yes
C
Statement 1: No; Statement 2: Yes; Statement 3: Yes
D
Statement 1: Yes; Statement 2: Yes; Statement 3: No
E
Statement 1: No; Statement 2: No; Statement 3: No

Answer

Statement 1: No; Statement 2: No; Statement 3: Yes

The correct evaluation sequence is No, No, Yes. For Statement 1, Project Quantum's allotment is

750

hours (

500 \times 1.50

), meaning its

780

hours of total usage produce

30

overflow hours. Because Quantum logged

180

off-peak hours, all

30

overflow hours occurred off-peak and are exempt from fees, making Statement 1 inaccurate (No). For Statement 2, BioGene's waiver was submitted on March 12, missing the February 28 deadline for March, so its allotment remains

200

hours, making Statement 2 inaccurate (No). For Statement 3, AstroPhysics has a

500

-hour allotment and used

540

hours, exceeding its allotment by

40

hours, making Statement 3 accurate (Yes).

Step-by-Step Solution

Evaluate Statement 1 (Project Quantum monetary overflow penalties)

Project Quantum is Tier-1 (

500

base) with an international partner and an ethics waiver filed January 15 (before the Feb 28 deadline). Allotment =

500 \times 1.50 = 750

node-hours. Total usage =

780

node-hours, resulting in

30

overflow hours (

780 - 750 = 30

). Quantum logged

180

off-peak hours. Since

30 \le 180

and

30 \le 100

(the off-peak cap), all overflow hours occurred during off-peak hours and incur zero monetary penalty. Statement 1 is No.

Applying the 50% incentive rule from Tab 1, filing deadline from Tab 3, and off-peak overflow exception from Tab 1.

Evaluate Statement 2 (Project BioGene modified baseline allotment)

Project BioGene is Tier-2 (

200

base) with an international partner. However, its ethics waiver was filed on March 12, which is after the February 28 deadline required for March applicability (Tab 3). Therefore, its allotment remains the baseline of

200

node-hours, not

300

node-hours (

200 \times 1.50 = 300

). Statement 2 is No.

Synthesizing policy qualification requirements in Tab 1 with deadline constraints in Tab 3.

Evaluate Statement 3 (Project AstroPhysics baseline excess)

Project AstroPhysics is Tier-1 (

500

base) without international co-investigators, so its allotment is

500

node-hours. Total March usage =

540

node-hours.

540 - 500 = 40

node-hours excess over allowable baseline allotment. Statement 3 is Yes.

Direct calculation of usage versus qualified baseline allotment across Tab 1 and Tab 2.

Key Concept

Dichotomous multi-tab evaluation requires integrating policy exceptions, deadline constraints, and quantitative thresholds across disparate information sources.
